<strong>Honey</strong> was used as a wound dressing in ancient times but was<br />

replaced by antiseptics and antibiotics in <strong>the</strong> 19th and 20th<br />

centuries, respectively. Hone}' has recently regained favor—<br />

with scientific evidence to back it up—as a treatment <strong>for</strong><br />

chronic wounds. <strong>Honey</strong> is being used lo manage venous,<br />

One percent to 2% <strong>of</strong> <strong>the</strong> inhabitants<br />

<strong>of</strong> developed countries<br />

have a chronic wound In <strong>the</strong><br />

United States, more than 6 million<br />

chronic wounds are treated each<br />

year, at a cost <strong>of</strong> >520 billion."<br />

<strong>Wounds</strong> are considered chronic if<br />

Lhey do not heal within 3 months/<br />

Depending on <strong>the</strong> cause, chronic<br />

wounds may be classified into one<br />

<strong>of</strong> four categories: venous ulcers,<br />

arterial ulcers, diabetic ulcers, and<br />

pressure ulcers (Table i). Venous<br />

ulcers, which occur as a result <strong>of</strong><br />

chronic venous insufficiency,<br />

account <strong>for</strong> about one-half <strong>of</strong><br />

chronic lower-extremity wounds,<br />

and affect 0.14%-2% <strong>of</strong> <strong>the</strong> population."<br />

Arterial ulcers result from<br />

poor arterial perfusion and comprise<br />

~25% <strong>of</strong> leg ulcers.' Diabetic<br />

ulcers occur in patients with diabetes<br />

mellitus (DM) and art due to<br />

impaired circulation and sensation<br />

in <strong>the</strong> lower extremities. The prevalence<br />

<strong>of</strong> foot ulcers in patients with<br />

DM is 12.7%." This patient group<br />

also has a lifetime risk <strong>of</strong> 15%-<br />

25% <strong>of</strong> developing a lower-extremity<br />

ulcer, making DM <strong>the</strong> wading<br />

cause <strong>of</strong> non-traumatic amputations<br />

in <strong>the</strong> United States. Pressure<br />

ulcers are caused by unrelieved pressure<br />

or shear, which causes damage<br />

to <strong>the</strong> tissue: <strong>the</strong> prevalence <strong>of</strong> pressure<br />

ulcers rises with age.'<br />

PRIMARY CARE<br />

Treatment <strong>of</strong> chronic wounds<br />

poses a challenge. A favorable outcome,<br />

represented by a healing<br />

wound, depends on maintaining a<br />

moist wound bed, removing necrotic<br />

tissue without harming healthy<br />

tissue, and preventing and treating<br />

infection. Some readers may be surprised<br />

to learn that <strong>the</strong> application<br />

<strong>of</strong> honey to chronic wounds has<br />

been shown to facilitate a healing<br />

wound environment.'•'<br />

The use <strong>of</strong> honey as a treatment<br />

<strong>for</strong> wounds dates back to <strong>the</strong> time<br />

<strong>of</strong> <strong>the</strong> ancient Egyptians and<br />

Creeks." Therapeutic use <strong>of</strong> honey<br />

was abandoned in <strong>the</strong> latter half <strong>of</strong><br />

<strong>the</strong> 19th century and early 20th<br />

century following <strong>the</strong> introduction<br />

<strong>of</strong> antiseptics and <strong>the</strong>n antibiotics.<br />

However, <strong>the</strong> development <strong>of</strong><br />

multi-drug-resistant bacteria and<br />

<strong>the</strong> rising incidence <strong>of</strong> chronic<br />

wounds have led to a reconsideration<br />

<strong>of</strong> <strong>the</strong> use <strong>of</strong> honey in treating<br />

wounds.: 1<br />

The US food and Orug Administration<br />

has approved two<br />

<strong>the</strong>rapeutic honeys <strong>for</strong> use in this<br />

country. Medihoney Antibacterial<br />

Medical <strong>Honey</strong> and Active Manuka<br />

<strong>Honey</strong>. Both honeys are derived<br />

from <strong>the</strong> manuka bush in New-<br />

Zealand (also known as Leptospermum<br />

scoparium). These honeys<br />

have been sterilized, but not inactivated,<br />

through gamma irradiation,<br />

which destroys Clostridium spores.<br />

The honeys contain a unique manuka<br />

factor, which gives <strong>the</strong>m additional<br />

antibacterial activity and<br />

distinguishes <strong>the</strong>m as<br />

<strong>the</strong>rapeutic<br />

honeys. These honeys are safe, easy<br />

to use, and cost effective, and have<br />

emerged as wound treatments that<br />

can achieve a variety <strong>of</strong> <strong>the</strong>rapeutic<br />

outcomes.••' Of note, culinary<br />

honey purchased in a supermarket<br />

is not medical grade and not suitable<br />

<strong>for</strong> this use.<br />

Some NTs may be unaware <strong>of</strong><br />

recent research supporting <strong>the</strong> use<br />

<strong>of</strong> honey in wound care."<br />

Although evidence suggests that<br />

honey is beneficial in treating<br />

acute wounds, this integrative<br />

review examines <strong>the</strong> use <strong>of</strong> honey<br />

as a treatment <strong>for</strong> chronic wounds,<br />

identifies indications <strong>for</strong> <strong>the</strong> use <strong>of</strong><br />

honey in this regard, describes <strong>the</strong><br />

application procedure, and discusses<br />

parameters that must<br />

be<br />

monitored as indicators <strong>of</strong> treatment<br />

effectiveness.<br />

<strong>Honey</strong>-making Pnxess<br />

Bees collect nectar from flowering<br />

plants and <strong>the</strong>n transport <strong>the</strong> nectar<br />

to worker bees in a hive,<br />

Hnzymes in <strong>the</strong> worker bees' stomachs,<br />

two <strong>of</strong> which are important<br />

to wound healing, break down <strong>the</strong><br />

nectar so that it is both more<br />

digestible <strong>for</strong> <strong>the</strong> bees and less like-<br />

!v to be attacked bv bacteria while<br />

stored in <strong>the</strong> hive. The first<br />

enzyme, glucose oxidase, converts<br />

glucose to gluconolactone, which<br />

yields gluconic acid and hydrogen<br />

peroxide. The second enzyme, catalase,<br />

which is active in l. scoparium,<br />

helps manage biobimlen (ie, <strong>the</strong><br />

amount <strong>of</strong> bacteria or. a wound<br />

surface be<strong>for</strong>e it is sterilized) in<br />

wound fluid, tissue, blood, and<br />

o<strong>the</strong>r body fluids. Bees <strong>the</strong>n<br />

spread <strong>the</strong> nectar throughout <strong>the</strong><br />

honeycombs, where some <strong>of</strong> <strong>the</strong><br />

water evaporates from it, resulting<br />

in honey.<br />

Therapeutic Effects <strong>of</strong> <strong>Honey</strong><br />

<strong>Honey</strong> affects wound healing<br />

through five modes <strong>of</strong> action: (1)<br />

antimicrobial properties, (2) antiinflammatory<br />

properties, (3) promotion<br />

<strong>of</strong> wound debridement<br />

with eschar or slough, (4)<br />

provision<br />

<strong>of</strong> a moist wound environment,<br />

and (5) reduction <strong>of</strong> wound<br />

malodor.'' Although <strong>the</strong> mechanisms<br />

by which honey exerts its<br />

<strong>the</strong>rapeutic effects are not well<br />

understood, researchers have<br />

shown that it exerts antimicrobial<br />

effects against even antibiotic-resistant<br />

bacteria.'<br />

<strong>Honey</strong>, even when diluted to a<br />

5% concentration, has been shown<br />

to be effective against clinical isolates<br />

<strong>of</strong> methicillin-resistant<br />

Staphylococcus aureus (MRSA), S<br />

-"• To date, honey has not been<br />

shown to inhibit <strong>the</strong> growth <strong>of</strong><br />

Serratia marcescens or Candida albicans,<br />

or to inhibit <strong>the</strong> growth <strong>of</strong><br />

Pseudomonas aeruginosa in patients<br />

with cystic fibrosis.14<br />

Several properties <strong>of</strong> honey are<br />

thought to play a role in its antimicrobial<br />

activity. The acidic pH (3.2-<br />

4.2) <strong>of</strong> honey may help stimulate<br />

Fibroblast activity within <strong>the</strong><br />

wound." <strong>Honey</strong>'s osmolarity pulls<br />

intracellular fluid into <strong>the</strong> wound,<br />

which dilutes <strong>the</strong> honey. Glucose<br />

oxidase is <strong>the</strong>n activated, which<br />

produces hydrogen peroxide at low<br />

levels, <strong>the</strong>reby decreasing bacterial<br />

growth. The hydrogen peroxide<br />

produced is 1000 times lower than<br />

<strong>the</strong> 3% solution typically used to<br />

clean wounds,1'" but even at this<br />

low concentration, <strong>the</strong> hydrogen<br />

peroxide maintains its antimicrobial<br />

activity." '<br />

The antibacterial effect <strong>of</strong><br />

honey is determined by its plant<br />

source and how it was processed."<br />

ViuJlai and Menon ~ compared <strong>the</strong><br />

antibacterial activity <strong>of</strong> four different<br />

types <strong>of</strong> honey—khadikraft<br />

honey, manuka honey, hea<strong>the</strong>r<br />

honey, and local honey from beekeepers<br />

in a south Indian village—<br />

against a total <strong>of</strong> 152 strains <strong>of</strong><br />

Pseudomonas cultured from diabetic<br />

ulcers, infected burns, and<br />

blood. The four honeys were diluted<br />

widi sterile Mueller-Hinton agar<br />

to obtain concentrations ranging<br />

from 1% to 25%. Nutrient agar<br />

without honey served as <strong>the</strong><br />

growth control and chloroxylenol<br />

was <strong>the</strong> antiseptic control The<br />

lowest concentration <strong>of</strong> honey that<br />

prevented growth on <strong>the</strong> isolates<br />

was recorded as <strong>the</strong> minimum<br />

inhibitory concentration (MIC).<br />

Khadikraft honey was <strong>the</strong> most<br />

effective against P aeruginosa, with<br />

an MIC <strong>of</strong> 11%; an MIC <strong>of</strong> 20%<br />

was needed <strong>for</strong> <strong>the</strong> o<strong>the</strong>r three<br />

honeys. Pseudomonas species are<br />

frequently resistant to antimicrobial<br />

<strong>the</strong>rapy, but honey that has an<br />

MIC <strong>of</strong> 10%-20% is effective in<br />

preventing its growth in wounds. "<br />

Although chronic inflammation<br />

appears to decrease when<br />

honey <strong>the</strong>rapy is used, clinical<br />

studies have not been able to clearly<br />

identify how this anti-inflammatory<br />

effect occurs." Monocytes are<br />

activated by honey to release interleukin<br />

(II.)-6, IL-1, and tumor<br />

necrosis factor-1.'4 Pain is reduced<br />

in <strong>the</strong> wound because <strong>of</strong> <strong>the</strong><br />

decreased edema, which improves<br />

circulation. Subrahmanyam et af<br />

compared honey with silver sulfadiazine<br />

in a randomized controlled<br />

trial (RCI) in 60 patients<br />

with burns, and found that honey<br />

decreased free radicals stimulated<br />

by excessive inflammation, <strong>the</strong>reby<br />

reducing scarring.<br />

Wound debridement by honey<br />

has been noted through several<br />

mechanisms. Autolytic debridement<br />

occurs because <strong>of</strong> <strong>the</strong> extra<br />

moisture pulled from lymph fluid.<br />

The osmotic action cleanses <strong>the</strong><br />

wound base and s<strong>of</strong>tens slough<br />

and necrotic tissue 11 Hydrogen<br />

peroxide produced by honey<br />

chemically also debrides <strong>the</strong><br />

wound; <strong>the</strong> honey reacts with ferrous<br />

ions, producing <strong>the</strong> radical<br />

hydroxy!, which causes antibacterial<br />

activity.••' In an RTC comparing<br />

<strong>the</strong> effectiveness <strong>of</strong> manuka honey<br />

and hydrogel dressing in 73<br />

patients with necrotic lowerextremity<br />

ulcers infected with S<br />

aureus (n = 41), MRS A (n = 16), or<br />

P aeruginosa (n = 16), MRSA was<br />

eliminated in 70% <strong>of</strong> <strong>the</strong> manuka<br />

honey-treated wounds versus 16%<br />

<strong>of</strong> <strong>the</strong> hydrogel-treated wounds<br />

after 4 weeks.' P aeruginosa was<br />

eliminated in 33% <strong>of</strong> honey-treated<br />

wounds versus 50% <strong>of</strong> <strong>the</strong><br />

hydrogel-treated wounds. The<br />

authors concluded that when <strong>the</strong><br />

slough is debrided and MRSA is<br />

eliminated, <strong>the</strong> infection rate is<br />

decreased.<br />

The moist environment cieated<br />

by <strong>the</strong> honey protects <strong>the</strong> wound,<br />

reduces infection rates, reduces<br />

pain, debrides necrotic tissue, and<br />

promotes granulation tissue <strong>for</strong>mation.''<br />

Epi<strong>the</strong>lialization can<br />

occur on <strong>the</strong> surface <strong>of</strong> <strong>the</strong> wound<br />

ra<strong>the</strong>r than below <strong>the</strong> eschar, as<br />

occurs in dry wounds. The wound<br />

bed is protected by honey's high<br />

viscosity, which provides a barrier<br />

to infection, and by <strong>the</strong> osmotic<br />

activity <strong>of</strong> honey, which promotes<br />

autolytic and mechanical debridement."<br />

2' <strong>Honey</strong> also reduces<br />

wound odor. When honey is used<br />

to treat wounds, glucose, ra<strong>the</strong>r<br />

than amino acids, is produced as<br />

<strong>the</strong> bacteria metabolize serum and<br />

dead cells. Lactic acid is <strong>the</strong>n produced,<br />

which is less malodorous<br />

dian ammonia, amines, or sulfur<br />

compounds.'4<br />

Syn<strong>the</strong>sis <strong>of</strong> <strong>the</strong> Literature<br />

A systematic literature search was<br />

done using <strong>the</strong> electronic databases<br />

CINAHI. and Medline and <strong>the</strong><br />

Web engine Google Scholar and<br />

<strong>the</strong> key words honey, wounds, and<br />

chronic wounds. Thirty-four articles<br />

were reviewed and assessed <strong>for</strong><br />

validity The authors evaluated


RCTs and case series to ascertain<br />

<strong>the</strong> effect <strong>of</strong> honey on chronic<br />

wounds such as lower-extremity<br />

ulcers, pressure ulcers, bums, diabetic<br />

ulcers, and slow-healing<br />

wounds in oncology.<br />

Lower-extremity Ulcers—In a<br />

comparative study, Cethin and<br />

Cowman-' used manuka honey to<br />

treat 8 patients with chronic leg<br />

ulcers that had not shown<br />

improvement with o<strong>the</strong>r wound<br />

care <strong>for</strong> 4 weeks. Wound odor was<br />

eliminated after <strong>the</strong> first honey<br />

application, pain duration was<br />

decreased from 2 hours to 30 minutes<br />

(per patient report), and <strong>the</strong><br />

size <strong>of</strong> <strong>the</strong> wound was reduced by<br />

54.8% after 4 weeks <strong>of</strong> <strong>the</strong>rapy.<br />

Smith et al-'" applied Medihoney to<br />

11 chronic lower-extremity venous<br />

ulcers that had failed to respond to<br />

various treatments, including compression,<br />

topical silver, non adherent<br />

dressings, and antibiotic<br />

<strong>the</strong>rapy. All <strong>of</strong> <strong>the</strong> wounds healed<br />

after 3-6 weeks <strong>of</strong> continuous treatment.<br />

Robson et al'5 found that <strong>the</strong><br />

average time to healing was 100<br />

days in <strong>the</strong> Medihoney group versus<br />

140 days in <strong>the</strong> standard-<strong>the</strong>rapy<br />

(control) group <strong>for</strong> lowerextremity<br />

ulcers.<br />

In 3 case studies <strong>of</strong> patients<br />

with leg ulcerations, use <strong>of</strong><br />

Medihoney promoted significant<br />

healing over 2-8 weeks and<br />

reduced pain (per patient report)<br />

and infection (per repeat swab cultures)<br />

in ail cases." In a study <strong>of</strong> 6<br />

patients with non-healing wounds,<br />

use <strong>of</strong> honey produced <strong>the</strong> favorable<br />

outcomes <strong>of</strong> granulation and<br />

reduction <strong>of</strong> bacterial burden over<br />

a mean <strong>of</strong> 4 weeks. ' One patient in<br />

this study who had been experiencing<br />

severe pain was able to stop<br />

using an opioid analgesic after 17<br />

days <strong>of</strong> honey gel treatment and no<br />

longer needed any analgesic after 6<br />

weeks <strong>of</strong> treatment. <strong>Use</strong> <strong>of</strong> honey<br />

achieved <strong>the</strong> goals <strong>of</strong> reducing bacterial<br />

load, inflammation, and<br />

pain. By contrast, in a study conducted<br />

on patients over a 12-week<br />

time period, kill et a!-"' found that<br />

honey with compression, compared<br />

with compression alone, did<br />

not significantly increase healing<br />

<strong>of</strong> venous leg ulcers.<br />

Diabetic Ulcers—<strong>Honey</strong> was<br />

used in an elderly man with chronic<br />

diabetic heel and <strong>for</strong>efoot ulcers<br />

<strong>of</strong> 14 months' duration."' The<br />

patient had lost two toes, had<br />

undergone four surgeries, and had<br />

been hospitalized 5 times in<br />

attempts to heal <strong>the</strong> ulcers.<br />

Cultures <strong>of</strong> <strong>the</strong> wound were positive<br />

<strong>for</strong> MRSA, V'RK, and Pseudomonas,<br />

<strong>Honey</strong> was applied daily;<br />

after 2 weeks, granulation tissue<br />

was noted. The ulcers resolved over<br />

12 months.<br />

Pressure Ulcers—Van der<br />

Weydenw used honey dressings to<br />

treat 2 patients with pressure<br />

ulcers. One patient had a stage 3<br />

ulcer and <strong>the</strong> o<strong>the</strong>r patient had a<br />

stage 4 ulcer; both patients' ulcers<br />

healed after 8-11 weeks <strong>of</strong> treatment.<br />

The patient with <strong>the</strong> stage 4<br />

sacral wound had been treated <strong>for</strong><br />

4 weeks with a hydrocolloid dressing,<br />

with little effect. However,<br />

after 1 week <strong>of</strong> honey treatment,<br />

<strong>the</strong> necrotic tissue began to break<br />

down and after 3 weeks, <strong>the</strong><br />

necrotic tissue was gone. Granulation<br />

tissue was noted after 4<br />

weeks. The o<strong>the</strong>r patient had been<br />

treated with a hydrocolloid dressing<br />

<strong>for</strong> 3 weeks, with no improvement.<br />

One week after starting <strong>the</strong><br />

honey dressing, improvement was<br />

noted, and after 23 days, <strong>the</strong><br />

wound was shallow and granulating.<br />

Acton" used honey to debride<br />

pressure ulcers, with favorable<br />

results. In one case in which a<br />

necrotic pressure ulcer had been<br />

present <strong>for</strong> ) month, <strong>the</strong> necrotic<br />

tissue was absent after 5 days <strong>of</strong><br />

treatment. In ano<strong>the</strong>r case, a<br />

necrotic hip wound was clean after<br />

8 weeks <strong>of</strong> honey use. A 5-week<br />

RCT assessed <strong>the</strong> use <strong>of</strong> honey in<br />

15 patients with 25 stage 2-3 pressure<br />

ulcers versus ethoxy-diaminoacridine/nitr<strong>of</strong>urazone<br />

in 11<br />

patients with 25 stage 2-3 pressure<br />

ulcers.0 The honey-treated group,<br />

relative to <strong>the</strong> control group, experienced<br />

approximately 4 times <strong>the</strong><br />

rate <strong>of</strong> pressure ulcer healing.<br />

Burns—Subrahmanyam et al<br />

treated 100 patients with burns<br />

with a honey dressing or a silver<br />

sulfadiazine dressing. At 7 and 14<br />

days, greater healing was noted earlier<br />

in <strong>the</strong> honey group than in <strong>the</strong><br />

silver sulfadiazine group. The silver<br />

sulfadiazine group showed persistent<br />

infection on bacterial cultures,<br />

whereas cultures in <strong>the</strong> honey<br />

group were 90% sterile. These<br />

authors reported that 50 patients<br />

with bums treated with early exci<br />

sion and skin grafting instead <strong>of</strong><br />

honey had better functional and<br />

cosmetic results after 3 months.<br />

<strong>Wounds</strong> in Patients with<br />

Cancer—<strong>Honey</strong> has been used to<br />

treat slow-healing wounds in<br />

patients with cancer, particularly in<br />

neonate and pediatric populations.<br />

In a study by Simon et al,,: honey<br />

was found effective against nosocomial<br />

wound infections. These<br />

investigators studied wound cultures<br />

growing MRSA, VR1-, and P<br />

aeruginosa from 14 patients whose<br />

slow wound healing was related to<br />

chemo<strong>the</strong>rapy and radiation toxicity,<br />

malnutrition from nausea/<br />

vomiting, mucositis, or infection.<br />

Healing was noted after an average<br />

use <strong>of</strong> 22 days in all wounds.<br />

Patients and <strong>the</strong>ir parents were<br />

pleased with <strong>the</strong> results.<br />

work <strong>for</strong> wound healing, developed<br />

by Schultz et al," focuses on<br />

preparing <strong>the</strong> wound bed by modifying<br />

factors that delay or prevent<br />

healing. Wound-bed preparation<br />

includes management <strong>of</strong> 4 factors:<br />

T = nonviable or deficient tissue;<br />

I = infection or inflammation;<br />

M = moisture imbalance; and<br />

E = a non-advancing or undermined<br />

wound edge.<br />

NPs can use this framework in <strong>the</strong><br />

<strong>of</strong>fice to aid in assessment <strong>of</strong><br />

wound healing.<br />

Choosing an \npropriate<br />

Dressing —<strong>Honey</strong> dressings are<br />

available in different <strong>for</strong>ms, <strong>the</strong><br />

type used depends on <strong>the</strong> amount<br />

<strong>of</strong> wound exudate." <strong>Wounds</strong> are<br />

first cleaned using a facilityapproved<br />

wound cleanser. The<br />

outei margins are protected with<br />

skin prep. Hie dressing is applied to<br />

fit within <strong>the</strong> wound margins. For a<br />

lightly draining wound, use <strong>of</strong> a<br />

honeycolloid (non-adhesive) without<br />

a cover dressing is suggested.<br />

For a lightly to moderately draining<br />

wound, use <strong>of</strong> a honey gel/ointment<br />

and an occlusive dressing designed<br />

to maintain a moist environment is<br />

indicated. One challenge with use<br />

<strong>of</strong> a liquid/gel honey is ensuring<br />

that it stays in place; this preparation<br />

may not be optimal <strong>for</strong> a leg or<br />

abdominal wound. Frequency <strong>of</strong><br />

dressing changes depends on <strong>the</strong><br />

amount <strong>of</strong> drainage (Table 2). An<br />

outer dressing that becomes saturated<br />

is changed promptly to avoid<br />

maceration <strong>of</strong> <strong>the</strong> peri-wound skin<br />

and to prevent contamination. As<br />

drainage decreases, dressings are left<br />

on <strong>for</strong> longer periods <strong>of</strong> time, typically<br />

4-7 days/1 For moderately to<br />

heavily draining wounds, ano<strong>the</strong>r<br />

available dressing is Medihoney, a<br />

5% calcium alginate and 95%<br />

Lepiospermum honey that is frequently<br />

used on lower-extremity<br />

ulcers under a compression wrap.5-"<br />

Although honey is generally<br />

safe when used to treat wounds, a<br />

few contraindications exist. Patients<br />

with a known history <strong>of</strong> allergy to<br />

honey or bee venom should not<br />

use honey dressings. Patients widi<br />

DM need to monitor dieir blood<br />

glucose levels more frequently<br />

because <strong>of</strong> <strong>the</strong> risk <strong>for</strong> hyperglycemia.'"<br />

Fur<strong>the</strong>rmore, honey<br />

should not be used on stable, dry<br />

eschar on heels, as diis is <strong>the</strong> body's<br />

natural protection, or on wounds<br />

that need surgical debridement/-'<br />

Evaluation <strong>of</strong> Therapy--As<br />

with any topical dressing, <strong>the</strong>se<br />

questions must be answered when<br />

assessing <strong>the</strong> effectiveness <strong>of</strong> honey<br />

in treating a wound: (1) Have redness<br />

and swelling (ie, inflammation)<br />

decreased? (2) Has pain<br />

decreased? (3) What is <strong>the</strong> condition<br />

<strong>of</strong> <strong>the</strong> surrounding skin? Is it<br />

improving? (4) Is <strong>the</strong> number <strong>of</strong><br />

dressing changes decreasing over<br />

time? (If not, <strong>the</strong> honey may not<br />

be effective because <strong>of</strong> <strong>the</strong> amount<br />

<strong>of</strong> drainage.) (5) Has <strong>the</strong> necrotic<br />

tissue diminished? (6) Is <strong>the</strong><br />

wound odor decreasing? (7) Is <strong>the</strong><br />

treatment cost-effective?1"' F.ven<br />

though honey has atuibacterial<br />

properties, systemic antibiotics<br />

may still be needed. Monitoring<br />

<strong>the</strong> wound is required.<br />

Implications <strong>for</strong> Education<br />

Nurse practitioners and wound<br />

care nurses must be educated<br />

about <strong>the</strong> use <strong>of</strong> honey and its<br />

indication <strong>for</strong> <strong>the</strong> treatment <strong>of</strong><br />

chronic wounds. <strong>Honey</strong> dressings<br />

are easy to apply, non-adherent to<br />

<strong>the</strong> wound base, and less painful<br />

than o<strong>the</strong>r dressings on removal."<br />

<strong>Honey</strong> can be used in cavity<br />

wounds or a sinus tract because <strong>the</strong><br />

residual can be cleaned out at<br />

dressing changes. 1 loney is appropriate<br />

<strong>for</strong> wounds with moderate<br />

to heavy amounts <strong>of</strong> drainage, with<br />

slough or eschar needing chemical<br />

debridement, and with an odor/'11<br />

<strong>Honey</strong> <strong>for</strong> wound treatment must<br />

be <strong>of</strong> a medical grade that is regulated<br />

safe, effective, and cast-effective.<br />

Implications <strong>for</strong> Research<br />

Fur<strong>the</strong>r studies specifically RCTs,<br />

are needed to assess <strong>the</strong> use <strong>of</strong><br />

newly developed honey-impregnated<br />

dressings. According to Simon et<br />

af - many case studies, but only a<br />

few RCis, have been reported


PRIMARY CARE<br />

regarding <strong>the</strong> <strong>the</strong>rapeutic use <strong>of</strong><br />

honey. More data are needed to<br />

assess <strong>the</strong> effect <strong>of</strong> medical grade<br />

honey at <strong>the</strong> molecular level (ie, its<br />

antimicrobial and antioxidant<br />

activity and elimination <strong>of</strong> free radicals<br />

within <strong>the</strong> wound).11'<br />

Additional clinical studies are<br />

needed to determine optimal<br />

dosage regimens <strong>for</strong> antimicrobial<br />

efficacy.'<br />

Conclusion<br />

<strong>Use</strong> <strong>of</strong> honey as a treatment <strong>for</strong> a<br />

variety <strong>of</strong> wounds is supported by<br />

research. 1 loney has antibacterial<br />

activity against MRSA, Pseudomonas,<br />

and VRP,; it also reduces<br />

odor and helps debride wounds.<br />

<strong>Honey</strong>'s anti-inflammatory activity<br />

has been shown to reduce edema<br />

and exudate and minimize scarring.'1<br />

<strong>Honey</strong> can be removed<br />

painlessly with use <strong>of</strong> a non-adherent<br />

dressing. <strong>Use</strong> <strong>of</strong> honey is gradually<br />

becoming more widespread<br />

and may be well received by<br />

patients, who perceive it to be a<br />

natural product '" J •<br />

I can heal wounds with honey and so can you<br />

ALLEN DENNISON<br />

T<br />

he Crowne Plaza Hotel in Warwick<br />

resembles a decent beehive even on<br />

a slack day. It is swarming with conferees<br />

and employees moving in and<br />

out <strong>of</strong> chambers consuming sweet food.<br />

Some people arrive by air from nearby T.F.<br />

Green AiTport on low-cost fares. There is a<br />

high soda! organization.<br />

Next week, on July 25-29, management<br />

will show extreme cooperation in welcoming<br />

20 beehives and 500 beekeepers <strong>for</strong> <strong>the</strong> annual<br />

meeting <strong>of</strong> <strong>the</strong> Eastern Apiculture Society.<br />

They will have talks on Colony Collapse Disorder,<br />

practical beekeeping including a bee<br />

yard, <strong>the</strong> business <strong>of</strong> keeping an apiary and<br />

treating illness with bee products and stings.<br />

On Wednesday <strong>the</strong>y will be regaled by<br />

Rhode Island's own Charlie Hall and <strong>the</strong><br />

Ocean State Follies, who will sting <strong>the</strong>m all in<br />

a show <strong>the</strong>y will not soon <strong>for</strong>get. If you have<br />

even a passing interest in bees, I recommend<br />

that you go to <strong>the</strong> Web site eastemapiculture<br />

.org and sign up <strong>for</strong> a day or two.<br />

I am presenting my literature review and<br />

work among <strong>the</strong> elderly in healing wounds<br />

with honey, based on 30 years <strong>of</strong> <strong>of</strong>fice practice<br />

and work as a medical director <strong>of</strong> Kvergreen<br />

House Health Center, a nursing home<br />

in East Providence. 1 remember a comic TV<br />

routine with Met Brooks interviewing Sid<br />

Caesar posing as a great Egyptologist. "So<br />

pr<strong>of</strong>essor, what is <strong>the</strong> secret <strong>of</strong> Tutankhamen's<br />

Tomb?" Quipped Caesar, "Twenty<br />

years <strong>of</strong> research and 1 should tell you?"<br />

1 am going to tell you. Speaking <strong>of</strong> F.gyptian<br />

tombs, did you know that urns <strong>of</strong> honey<br />

were found undegraded in several tombs in<br />

ancient Egypt? This tells volumes about <strong>the</strong><br />

amazing chemical nature <strong>of</strong> honey <strong>for</strong><br />

wound-healing, to say nothing <strong>of</strong> <strong>the</strong> long association<br />

ol <strong>the</strong> bees and humans.<br />

How does honey help to heal wounds and<br />

why is it superior to neosporin, bacit racin and<br />

prescription mupirocin (bactroban)? <strong>Honey</strong><br />

is bee spit but it is also <strong>the</strong>ir energy currency<br />

and <strong>the</strong>ir bank account. Just as "people get<br />

funny about <strong>the</strong>ir money" so, too, do bees get<br />

funny about <strong>the</strong>ir honey. They hate bears,<br />

bacteria and yeasts that may steal or spoil <strong>the</strong><br />

honey, For <strong>the</strong> bears <strong>the</strong>y have stingers, <strong>for</strong><br />

<strong>the</strong> inicro-onjanisms <strong>the</strong>y put amazing stuff<br />

in <strong>the</strong> honey. They also seal <strong>the</strong> hive with an<br />

antimicrobial substance called propilis.<br />

<strong>Honey</strong> is a mixture <strong>of</strong> concentrated sugars<br />

that immediately dehydrate a bacterial cell,<br />

rendering it immobile, though without necessarily<br />

killing it. Young Dr. Keith Monchik, <strong>of</strong><br />

<strong>the</strong> Orthopedic Service at Rhode Island Hospital<br />

(RIH), went to Haiti with our team from<br />

<strong>the</strong> Ocean State to treat earthquake victims.<br />

They ran out <strong>of</strong> usual wound-carc creams<br />

quickly but a senior military nurse reminded<br />

<strong>the</strong> team that sugar packs from <strong>the</strong>ir rations<br />

always work in a pinch to keep a wound from<br />

getting infected through <strong>the</strong> same mechanism.<br />

He reported gratifying results to <strong>the</strong><br />

RIH medical staff.<br />

The high osmotic value <strong>of</strong> honey draws fluids<br />

out <strong>of</strong> wounds. This decreases tissue pressure,<br />

thus admitting more new blood, with, <strong>of</strong><br />

course, oxygen, as well as healing elements<br />

> t^^il.m l« m,. nn vi,C*Om Will, AC fhP<br />

fluid hits <strong>the</strong> honey, small amounts <strong>of</strong> hydn><br />

gen peroxide are produced, very toxic to bacteria<br />

but not to fibroblasts and healing elements.<br />

<strong>Honey</strong> derived from medicinally active<br />

nectars such as tea tree and eucalyptus<br />

may have additional value, and <strong>the</strong> Food and<br />

Drug Administration has allowed <strong>the</strong>ir importation<br />

and marketing.<br />

Topical antibiotic creams and ointments —<br />

both over <strong>the</strong> counter and prescription — are<br />

commonly used <strong>for</strong> skin infections and<br />

wound healing. These include neosporin,<br />

bacitracin, "liipte-antibiotic" ointments and<br />

mupirocin. They sterilize <strong>the</strong> wound but also<br />

kill healing elements, leading to delayed<br />

wound closure. And <strong>the</strong>y <strong>of</strong>ten lead to confusing<br />

red bypersensibviiy reactions.<br />

Additionally, more and more bacteria are<br />

growing resistant to antibiotics, which is a<br />

terrific threat to all <strong>of</strong> us. Some are costly. We<br />

should avoid <strong>the</strong>se tike <strong>the</strong> plague. My wife,<br />

Jane Denruson, M.D., is a pediatrician and<br />

beekeeper. As our house experienced colony<br />

collapse with drone migration <strong>of</strong> our four<br />

boys to New York City and Washington, my<br />

wife had <strong>the</strong> time to take <strong>the</strong> Bee Course <strong>of</strong>fered<br />

by Rhode Island Beekeepers Association<br />

(RIBA) and start some hives. At <strong>the</strong><br />

monthly RIBA meetings I spoke with <strong>the</strong> older<br />

beekeepers and was fascinated to learn <strong>of</strong><br />

honey's medicinal benefits. Some <strong>of</strong> <strong>the</strong> older<br />

beekeepers suggested that 1 try using honey<br />

mixed with Aquaphor ointment on my patients<br />

with minor wounds and ulcers. <strong>Honey</strong><br />

at body temperature gets runny and dribbles<br />

on clo<strong>the</strong>s, leading to poor treatment adherence.<br />

Aquaphor was already my favorite<br />

healing ointment. It is well suited to mixing in<br />

equal parts with honey because <strong>the</strong> lanolin<br />

and mineral oil holds both aqueous and oily<br />

parts toge<strong>the</strong>r to treat a wound<br />

Mixing large batches withmc help <strong>of</strong> my<br />

mo<strong>the</strong>r in law, Jane Mackenzie, R.N., is<br />

sticky business indeed. She helps me pot it<br />

into little cosmetic jars <strong>for</strong> use in <strong>the</strong> nursing<br />

home. We heal <strong>the</strong> aquaphor to 110 degrees in<br />

<strong>the</strong> microwave but never put raw honey in <strong>the</strong><br />

microwave because it would rum its special<br />

qualities. And 1 urge you all: "Do this al<br />

hornet." You can't buv it already made up.<br />

If I were to try to sell this as a medicament,<br />

<strong>the</strong> Food and Drug Administration could<br />

have me jailed and impound all my ointment,<br />

because adequate studies on <strong>the</strong> effectiveness<br />

and safety <strong>of</strong> this compound have not<br />

been done. I lowever. iwo imported products,<br />

Medihoney and Manuka <strong>Honey</strong>, have passed<br />

FDA approval <strong>for</strong> wound-healing, 'lhey are<br />

derived from <strong>the</strong> eucalyptus and tea tree<br />

plant, respectively, whose nectars have supposedly<br />

superior qualities. These honeys are<br />

irriadiated lu inactivate trace amounts <strong>of</strong> botuiinum<br />

toxin and bacteria.<br />

i believe that raw honey needs no such<br />

help and that such help might even he counter-productive<br />

This treatment and <strong>the</strong> importation<br />

increases <strong>the</strong> cost <strong>of</strong> treatment, witb<br />

small nibes going <strong>for</strong> S5() to $100.1 insist on<br />

<strong>the</strong> real thing when treating serious or stubbom<br />

wounds hut <strong>for</strong> everyday use <strong>the</strong> product<br />

from your home lab will work very well<br />

on your cuts, burns and skin tears.<br />

If you have diabetes and;or congestive<br />

heart failure peripheral arterial-supply problems,<br />

no ointment is going to help. The problem<br />

is under <strong>the</strong> skin. You need a doctor <strong>for</strong> it.<br />

I invite colleagues and hospitals to begin randomized<br />

controlled trials on using local raw<br />

honey head to head against imported honey<br />

and <strong>the</strong> usual wound-care products. My hypo<strong>the</strong>sis<br />

is that we can control at low cost,<br />

such superbugs as methacillin-resistam staphyllococus<br />

aureus and vancomyrin-resistant<br />

enterococcousand <strong>the</strong> emergence <strong>of</strong> fur<strong>the</strong>r<br />

resistant superbugs by avoiding <strong>the</strong> usual<br />

antibiotics.<br />

Meanwhile, we'd be encouraging <strong>the</strong> development<br />

<strong>of</strong> new local hives, which are so<br />

important to pollination — and thus plant life<br />

and <strong>the</strong> broader ecosystem — nationally.<br />
