An in-treatment web-based survey was conducted in 2005 with 50 New York World Trade Center rescue and recovery workers, volunteers, and area residents and workers who were treated with Ayurvedic herbs for post-9/11 symptoms. The survey documented pretreatment efforts at symptom relief, post-treatment symptom impact, and the context for using the herbal intervention. Herbal treatment was administered and monitored by a private non-profit organization. The natural detoxification and immune-strengthening program consists of 4 herbal supplements developed by an Ayurvedic physician. A minimum 6-month basic program was recommended, but many participants continued to 1 year and longer. All 50 respondents reported high incidence of alleviation of previously intractable symptoms, chiefly respiratory symptoms, fatigue, and depression.
