deaths, heart attacks, <strong>an</strong>d strokes as a result <strong>of</strong> improper long term dietary aid<br />

administration (http://www.who.int/mediacentre/factsheet/fs134/en/print.html).<br />

The prices <strong>of</strong> pure isolated subst<strong>an</strong>ces from pl<strong>an</strong>ts are beyond <strong>the</strong> fin<strong>an</strong>cial<br />

resources <strong>of</strong> most people in developing countries (George & v<strong>an</strong> Staden, 2000).<br />

Isolated compounds from <strong>medicinal</strong> pl<strong>an</strong>ts might have <strong>the</strong> potential to be promoted to<br />

such <strong>an</strong> extent that it may result in a similar outcome as some syn<strong>the</strong>tic miracle<br />

compounds. The inappropriate use <strong>of</strong> some syn<strong>the</strong>tically produced drugs have<br />

facilitated <strong>the</strong> development <strong>of</strong> <strong>an</strong>timicrobial resist<strong>an</strong>ce, with its life threatening<br />

consequences (Lewis, 1995). Therefore it is essential that <strong>the</strong> correct dosage,<br />

safety, stability, efficacy <strong>an</strong>d o<strong>the</strong>r import<strong>an</strong>t factors pertaining to pl<strong>an</strong>ts used<br />

indigenously are thoroughly researched <strong>an</strong>d documented (El<strong>of</strong>f, 1998b).<br />

It was recommended by <strong>the</strong> WHO in 1996 to test <strong>an</strong>d document <strong>the</strong> different<br />

st<strong>an</strong>dards defining <strong>the</strong> identity, purity, <strong>an</strong>d potency <strong>of</strong> pl<strong>an</strong>ts used <strong>medicinal</strong>ly in <strong>the</strong><br />

form <strong>of</strong> a pl<strong>an</strong>t monograph. Thereby <strong>the</strong> monograph serves as a revised carbon<br />

copy <strong>of</strong> traditional herbal knowledge for future generations<br />

2.1.3 Traditional herbalism <strong>an</strong>d westernised biomedicine<br />

The WHO defines health as “a complete state <strong>of</strong> physical <strong>an</strong>d mental well being, <strong>an</strong>d<br />

not merely as <strong>an</strong> absence <strong>of</strong> disease or infirmity”<br />

(http://www.<strong>the</strong>l<strong>an</strong>cet.com/search/search.isa). In contrast to westernised biomedicine<br />

where <strong>the</strong> patient is viewed as a sum <strong>of</strong> org<strong>an</strong> systems, neurophysiological<br />

hydraulics <strong>an</strong>d where only <strong>the</strong> affected parts <strong>of</strong> <strong>the</strong> body are treated, traditional<br />

healers take a more holistic approach, looking at <strong>the</strong> whole body (physical, mental<br />

<strong>an</strong>d spiritual) (http://www.<strong>the</strong>l<strong>an</strong>cet.com/search/search.isa;<br />

http://www.conserveafrica.org/<strong>medicinal</strong>_pl<strong>an</strong>ts.rtf).<br />

The quality <strong>of</strong> herbal medicine is influenced by factors such as <strong>the</strong> location <strong>of</strong> growth<br />

<strong>an</strong>d correct identification <strong>of</strong> collected <strong>medicinal</strong> pl<strong>an</strong>ts<br />

(www.who.int/medicines/library/trm_polpers_eng.pdf). Besides <strong>the</strong> variability <strong>of</strong><br />

some <strong>medicinal</strong> pl<strong>an</strong>t <strong>the</strong>rapies, it has been used for millennia st<strong>an</strong>ding <strong>the</strong> test <strong>of</strong><br />
