Title: [Herbal preparations have both effects and side effects. Widespread usage dictates knowledge among physicians]. Author: Mattsson K, Nilsson I. Journal: Lakartidningen; 2002 Dec 12; 99(50):5095-7. PubMed ID: 12572302.

Clinical data support the efficacy for some of these drugs. None of them is free of adverse effects.

The lack of long-term studies is especially unfortunate since many of the drugs are used for a long time. The difference between American and Swedish legislation on herbal medicine products is described.[Abstract] [Full Text] [Related] [New Search]
