Hepatotoxicity associated with herbal products.

摘要

A significant number of herbal products have been associated with hepatotoxicity. Attribution of liver injury to a specific herbal pro-duct may be difficult. There are few clinical or laboratory manifestations that specifically suggest that liver injury is the result of aspecific herbal. Compounding this difficulty is that the patient may have liver disease from another cause, may be consuming other potentially hepatotoxic products, or may be using a contaminated herbal product. The most important clue often is the temporal relationship between initiation of the herbal product and the appearance of liver injury; of equal importance is the resolution of the injury following withdrawal of the herbal product.
