Hepatotoxicity Description

Liver injury attributable to chaparral was first reported in 1990 and subsequently more than two dozen cases of clinically apparent liver injury attributed to chaparral have been published. The time to onset varied from 3 weeks to several years, but was usually within 3 to 12 weeks of starting daily ingestion or increasing the daily dose. The pattern of injury was typically hepatocellular with an acute viral hepatitis-like presentation and marked elevations in serum aminotransferase levels, but minimal increase in alkaline phosphatase. Autoimmune and immunoallergic features were uncommon. Several reported cases have been severe and some have led to emergency liver transplantation. Subclinical cases and serum enzyme elevations without symptoms may occur but have not been well characterized. Despite the several reports of liver injury caused by chaparral, over-the-counter products with chaparral are still available commercially and on the internet. For unclear reasons, there have been no cases of liver injury clearly implicating chaparral published since 2005. (Source: LiverTox)
