Green tea is packed full of a chemical called L-theanine (it constitutes half of tea's total amino acids). L-theanine has the benefit that within 20 minutes of imbibing your tea and for the subsequent 120 minutes it can induce alpha wave brain activity which both improves mental acuity and relaxes and calms the nerves. Theanine is abundant in white, green and black teas and reportedly can relieve both mental and physical stress, and even in repeated and high doses has little or no adverse affects - physical or psychological - just calm relaxation.
Yet, this group, comprising one would suspect more than averagely heavy users of tea has seen recently across several threads repeated outbursts, of panic, irritability and bile targetting (quite often with marginal rationality) pollution, pesticides, heavy metals, fluoridation and Chinese business ethics.
Do those on such short fuses really drink all the tea they claim - or are we witnessing the emergence of a theanine resistant sub species?
