Brief description of Green Tea Extract
Green tea extract is derived from leaves of camellia sinensis, the plant from which green, black and oolong teas are made. Green tea extract is associated with several health benefits, many supported by preliminary scientific research. These benefits include potential cancer-fighting properties, and a strong antioxidant effect that protects the body from the damaging effect of free radicals. The scientific community notes, however, that continued research is necessary.
