From the Manufacturer:
Stimulates Immune Function. Contains Caffeine. Yogi Tea Green Tea Triple Echinacea is formulated to help keep your immune system in great shape. A highly concentrated Echinacea Extract and Kombucha-PureT are produced in one of the world's most advanced herbal laboratories and complement this unique immune support formula. Kombucha-PureT is produced without the use of refined sugar or black tea, and is made from Kombucha grown in a unique medium of 32 supporting Chinese herbs. The combination of three varieties of Organic Echinacea Root (Echinacea angustifolia, purpurea, pallida) provides a full spectrum of protection. Recent scientific research has shown that Echinacea is effective in giving the immune system a short-term boost, thereby promoting (among other actions) an increase in interferons, proteins that control immune functions to keep the body in balance. This herb also supplies three categories of Echinacea actives - caffeic acid derivatives (including cichoric acid), alkylamides and polysaccharides. These plant compounds work together to enhance immune function. Yogi Tea has also included Elder Berry, which in recent research was shown to be immune-enhancing and supportive of the respiratory system. The formula is further complemented with Ginseng, which is widely regarded as the ultimate immune- enhancer, and with Organic Green Tea (Camellia sinensis). Unlike other green teas, this special organic Green Tea has a delicate flavor with no bitterness. Green Tea Triple Echinacea can help you stay healthy.
