In this paper, studies on single Chinese medicinal herbs, composite prescriptions, and their active principles, which have been used against HIV both in China and abroad, are highlighted; and the results from clinical treatment of 158 HIV infected patients performed by a China-Tanzania Coordinating Group are also reported. Six of the patients displayed seronegative conversion and remained so in the follow-up for 10 to 15 months. The author assumes that the prescriptions and drugs strengthening the patients' resistance could enhance the efficacy of AIDS treatment.
