Hypericin against retrovirus

Evidence of antiviral effects has especially been shown for St. John s Wort [2,3,10], Plant preparations with different chemical composition have been assayed against various viruses and both, hypericin and pseudohypericin, were found to be particularly effective as virucidal agents. The two compounds have been shown to be active against a broad range of viruses and retroviruses, such as herpes simplex virus types I and II, vesicular stomatitis and influenza viruses, cytomegalovyrus and human immunodeficiency virus-1 [2,3,10,91,92].
