Participant A commented:
Thanks, Leo, for your comments and the teaguardian article; however, the article does not state that thearubigin has not been found to be an effective antioxidant, rather that it has not been isolated in health studies (which is quite a different matter). The Oxygen Radical Absorbance Capacity of green and black tea has been measured, with the capacity of black tea being slightly higher than that of green (see Tea for Health by Tissa Amarakoon, Tea Research Institute of Sri Lanka, 2004).
