Twenty-seven medicinal herbs reputed in ancient Chinese folklore to have anti-infective properties were extracted by boiling under reflux. The extracts were tested for inhibitory activity against the human immunodeficiency virus in the H9 cell line at concentrations nontoxic to growth of the H9 cells. One of the extracts (Viola yedoensis) was studied in greater depth. At a subtoxic concentration, this extract shut off completely the growth of HIV in virtually all experiments.
