Catechins make up a majority of the pholypenols found in green tea, with the most active and most extensively studied being EGCG. EGCG, which is unique to white and green tea.

      Hello, Herbal teas or herbal tisanes are made from different herbs they can be flowers, leaves, barks, seeds or roots. They’re not considered a true tea as they don’t contain the tea leaves from the tea plant camellia sinensis.

    It was interesting to learn that drinking green tea may help improve your bone health by increasing bone mineral density. My mom is worried about developing osteoporosis, because she doesn’t like to drink milk. I think she could really benefit from drinking tea so that her overall health, as well as her bone health, can be improved.
