USP proposes label cautions for black cohosh and green tea extract

The U.S. Pharmacopeia (USP) is proposing to require cautionary statements on the labels of dietary supplements that claim to contain USP-grade black cohosh (Actaea racemosa syn. Cimicifuga racemosa) or green tea (Camellia sinensis) extract. The proposed statements are:

Caution: In rare cases black cohosh has been reported to affect the liver. Discontinue use and consult a healthcare practitioner if you have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice.

Caution: Must take with a meal. In rare cases extracts from green tea have been reported to adversely affect the liver. Discontinue use and consult a healthcare practitioner if you have a liver disorder or develop symptoms of liver trouble, such as abdominal pain, dark urine, or jaundice.
