(Reuters Health) - A "medical food" sold as an arthritis treatment may have caused four cases of temporary liver damage, researchers reported Monday.
The product in question is called flavocoxid, sold under the brand-name Limbrel. It's a mix of plant compounds called flavonoids, including catechins -- substances best known as components of green tea.
Limbrel is considered a medical food, which makes it different from a dietary supplement. It is available by prescription only, to treat osteoarthritis -- the common, "wear-and-tear" form of arthritis caused by cartilage breakdown in the joints.
