Cytotoxic &<br />

Gadano et al. 2006<br />

genotoxic<br />

Antifungal<br />

Aqueous<br />

decoction &<br />

infusion<br />

(concentrations:<br />

1, 10, 100, 1000<br />

µL extract/mL<br />

culture)<br />

Essential oil &<br />

ointment made<br />

with essential oil<br />

Immunomodulatory Hydroalcoholic<br />

crude leaf extract<br />

(5 mg/kg<br />

intraperitoneally)<br />

Antileishmanial Essential oil; 30<br />

mg/kg/day<br />

administered<br />

intraperitoneally<br />

<strong>for</strong> 15 days<br />

Nematocidal<br />

Trypanocidal<br />

Water extract &<br />

ascaridole-free<br />

hexane-extracted<br />

aqueous extract<br />

Ascaridole &<br />

monoterpene<br />

hydroperoxides<br />

isolated from<br />

aerial parts<br />

In vitro: human<br />

lymphocyte cell<br />

cultures; negative<br />

control:<br />

Chenopodium album<br />

extract (because<br />

does not contain<br />

essential oil)<br />

In vitro: against 12<br />

dermatophyte<br />

species; in vivo:<br />

guinea pigs<br />

w/experimental ring<br />

worm<br />

In vivo: mice<br />

(C3H/HePas)<br />

In vitro & in vivo:<br />

Leishmania<br />

amazonensis;<br />

BALB/c mice<br />

infected<br />

experimentally<br />

In vitro: rat<br />

gastrointestinal<br />

smooth muscle;<br />

concentrations<br />

required to kill<br />

Caenorhabditis<br />

elegans<br />

In vitro:<br />

epimastigotes of<br />

Trypanosoma cruzi<br />

Effect Not Demonstrated<br />

Active; showed significant<br />

increase in chromosomal<br />

aberrations & frequency of<br />

sister chromatid<br />

exchanges; decreased<br />

mitotic index<br />

Strongly active in vitro<br />

against dermatophyte<br />

species & cured ringworm<br />

in animal model within 7-<br />

12 days<br />

Active; increased<br />

phagocytosis, nitric oxide<br />

production & cellular<br />

recruitment to lymphoid<br />

organs (results similar to<br />

concanavalin A, positive<br />

control)<br />

Active; 50% inhibition<br />

against promastigote &<br />

amastigote <strong>for</strong>ms at 3.7 &<br />

4.6 µg/mL; showed<br />

moderate toxicity on<br />

macrophages in mice;<br />

indicated dose was<br />

effective<br />

Showed no observable<br />

effect on smooth muscle<br />

contraction (unlike<br />

ascaridole); research<br />

supports safety of<br />

traditional use of this herb<br />

as an infusion<br />

Active; minimum<br />

inhibition concentrations<br />

were 23, 1.2, 1.6, 3.1 &<br />

0.8 mcmol depending on<br />

the constituent<br />
