Taiwan GABA Tea
GABA stands for Gamma-Aminobutyric Acid. Through a series of research, Japanese scholar Omori Masashi ( 大森 正司 ) confirmed it has a very powerful antihypertensive effect thanks to its extremely high content of γ-Aminobutyric acid (GABA) compared to other teas. The GABA content adds a thick layer of baked sweet potato taste to the tea and is proven to offer the drinker a soothing or relaxing feeling. GABA processing, which involves shade growing and then nitrogen sparging was developed by the Japanese and later perfected by the Taiwanese. The result is a tea that tastes great, at once stimulating and soothing to the nervous system.
