The use of complementary and alternative medicine (CAM) has grown dramatically over the last decade. Botanical treatments originating from plants have become especially popular for treating conditions such as anxiety and depression. Evidence suggests that the botanical St. John's wort has neurochemical activity similar to that of conventional medications. However, research on the safety and effectiveness of St. John's wort is limited. This study will determine the safety and effectiveness of St. John's wort in treating GSAD, a serious condition characterized by intense fear of various social situations that may cause embarrassment.
Participants will be randomly assigned to receive either St. John's wort or placebo daily for 10 weeks. Self-report scales will be used to assess participants' GSAD symptoms at study entry and at study completion. Blood collection will occur at every weekly study visit to determine the levels of St. John's wort in the blood.
