Organic Osmanthus GABA Oolong Tea Yahara Chocolate & Tea Notes: GABA stands for Gamma-Aminobutyric Acid. Through years of research, Japanese scholar Omori Masashi ( 大森 正司 ) confirmed that GABA tea 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. Free Shipping on orders of $85 or more.
