Allium vegetables, including welsh onions, have

been used for 3000 years as flavor-enhancing foods and

folk medicines. Little information is available,

however, on its pharmacologic effects.

Here in, the experiment about antihepatotoxic

effects of welsh onions (Allium fistuloswzz Linn) have'

been done,. In this experiment, the female rats were

divided randomly into three groups. One is normal

group. Group II was given an oral of carbon tetrachoride

with dose of 055 mg/g body weight. And the group

III was given an oral of an aqueous-extract of welsh

onions daily with dose of 20 g/kg body weigh for eight

days. And two hours later, by CC14. The antihepatotoxic

effect of welsh onions was examine through canges in

GPT plasma activity and observation on the extent or

damage in the liver.

From both the examination, group III showed

significantly differences with group II. It conclude

that the aqueous-extract of welsh onions contains

substances, which could inhibit liver cells damage

caused by carbon tetrachloride.
