A lozenge formulation of green tea, derived from the dried leaves of Camellia sinensis, with potential antioxidant and chemopreventive activities. Green tea lozenge contains polyphenols that may be responsible for its chemopreventive effect. The polyphenol fraction contains mainly epigallocatechin-3-gallate (EGCG) and other catechins, such as epicatechin (EC), gallocatechin gallate (GCG), epigallocatechin (EGC), and epicatechin gallate (ECG). Green tea polyphenols act as antioxidants and free radical scavengers, protecting cells from the damaging effects of reactive oxygen species (ROS). Check foractive clinical trials using this agent.
