Effect of Phyllanthus amarus on chronic carriers of hepatitis B virus.
Lancet. 2(8614):764-6, 1988 Oct 1.
"Abstract: In a preliminary study, carriers of hepatitis B virus were
treated with a preparation of the plant Phyllanthus amarus for 30 days.
22 of 37 (59%) treated patients had lost hepatitis B
surface antigen when tested 15-20 days after the end of the
treatment compared with only 1 of 23 (4%) placebo-treated controls. Some
subjects have been followed for up to 9 months. In no case has the
surface antigen returned. Clinical observation revealed few or no toxic
effects. The encouraging results of this preliminary study recommend
continued evaluation of this plant and the active principles isolated
Please note the small numbers of patients and the emphasis that this is
a preliminary study. A medline search shows that many researchers have
failed to confirm these findings, while others show promising, usually
in vitro, results.
