Green tea extract: is this herb safe in dog, cat diets?
Green tea extract has been around for centuries, but its use in pet foods is a very modern consideration that is long on extrapolation and short on proof of benefit.
Green tea extract is derived from the leaves of the Camellia sinensis bush. Dried green tea leaves are used to make the popular hot beverage, and the extracts play a central role in herbal medicine. More recently, purified extracts have found favor as a nutraceutical and food antioxidant preservative.
