Case ReportsAn unusual cause of burn injury: fig leaf decoction used as a remedy for a dermatitis of unknown etiology.
Medicinal plant extracts are commonly used worldwide. Their use relies mostly on historical and anecdotal evidence and might be so hazardous. Phytophotodermatitis is a well-known entity that is caused by the sequential exposure to certain species of plants containing furocoumarins and then to sunlight. ⋯ All reported cases to date have in common that patients are exposed to direct sunlight or to artificial UVA lights (like solarium) of varying durations. In our case neither direct sun exposure, other than inevitable indoor UVA influence, nor blister formation was present. The etiologic factors, symptoms, signs, course, and treatment alternatives for phytophotodermatitis are also reviewed briefly.

Star anise is used as herbal tea, for the treatment of colicky pain in infants. It may cause neurological troubles. ⋯ Confusion or blending between Chinese and Japanese star anise may cause poisoning. Japanese star anise is a neurotoxic plant indeed, because it contains sesquiterpenic lactones. From November 2001, star anise products are theoretically prohibited in France, but they may be still available in some small groceries, or imported by families themselves.

Cardiovascular adverse effects of herbal medicines: a systematic review of the recent literature.
Herbal medicines are popular but health care professionals often feel uncertain about their risks. This article summarizes recent evidence regarding the serious or potentially serious cardiovascular adverse effects of herbal medicines. Five electronic literature databases were searched. ⋯ Because of the anecdotal nature of the evidence, it is impossible to estimate the incidence of adverse effects. In conclusion, herbal medicinal products are regularly associated with serious cardiovascular adverse events but the size of this problem cannot be estimated at present. Vigilance and research seem to be the best way forward.

We describe a case of acute liver failure and death associated with the use of a preparation containing the "natural" anxiolytic kava (Piper methysticum) and passionflower (Passiflora incarnata). The patient died after a report by the Therapeutic Goods Administration (TGA) warning of the potential for hepatotoxicity associated with the use of kava-containing products. The general public and alternative medicine practitioners need to be aware of the potential for non-prescription drugs to cause serious hepatic reactions.
