Wuyi Cliff Oolong tea, the best of Oolong and one of 3 ingredients of Tava Tea, is a species of Camellia sinensis belonging to the family Theaceae, native the Wuyi Mountain area. Its leaves and leaf buds has been used as tea in Chinese culture and many places in the world, including Wuyi Rock Tea, Tie Guan Yin tea, Taiwan tea and Oolong tea, Iron Goddess of Mercy and other products in Fujian, etc.. Oolong can be bought as green or black tea but it is best known as a black tea in the process of withering under the strong sun and oxidation before curling and twisting.
6. Neutoxicity (Altering the normal activity of the nervous system)
With an aim to find an inactivator for botulinum neurotoxin in black, oolong, roasted, and green teas in the study of "Ethyl acetate extract from black tea prevents neuromuscular blockade by botulinum neurotoxin type A in vitro" by Satoh E.[6a], researcher found that extract pre-mixed with the toxin before the assay and not modified by mixing each extract with bovine serum albumin (BSA) before adding the toxin indicated that ethyl acetate extract from black tea is the best source for searching for tea-derived inactivating substance(s) of botulinum neurotoxin.
b. Thearubigin extract
Black tea extract, thearubigin fraction inhibited indirectly evoked twitches in in vitro mouse phrenic nerve-diaphragm preparations within 40 - 45 min, according to th study of "Black tea extract, thearubigin fraction, counteract the effects of botulinum neurotoxins in mice" by Satoh E, Ishii T, Shimizu Y, Sawamura S, Nishimura M.[6b] researchers suggested that thearubigin fraction of black tea may be of potential benefit in protecting the paralytic actions of botulinum neurotoxins (BoNTs).
c. Tetanus toxin
With an aim to find an inactivating substance for tetanus toxin in natural foodstuff, in the study of "Black tea extract, thearubigin fraction, counteracts the effect of tetanus toxin in mice" by Satoh E, Ishii T, Shimizu Y, Sawamura S, Nishimura M.[6c], researchers found that ]tetanus toxin to rat cerebrocortical synaptosomes was inhibited by mixing iodinated toxin with thearubigin fraction and suggested that this fraction may be able to apply for prophylaxis of tetanus.
