GABA is an inhibitory neurotransmitter also found in human bodies. Its main role is to reduce neuronal excitability. Research has shown that GABA contributes to preventing high blood pressure, helps with sleep disorders, and reduces stress and anxiety.

 

Thanks to the combination of GABA with other healthy nutrients specific to tea such as l-theanine and other polyphenols, GABA-rich tea has a deeper impact than regular green tea on chronic stress-induced autonomic imbalance, and related risks for cardiovascular disease (see examples of recent studies published here, here and here).

 

Grown by the producer of our super popular KOJI and KOTARO tamaryokucha, KOHEI greets you with a delicious gingerbread aroma when you first open its bag. Its beautiful pale golden liquor is sweet, refreshing, easy to drink, with hints of cinnamon and citrus notes and leaves a pleasant bitterness on the tongue. Its positive impact on sleep disorders and low levels of caffeine make it a great late afternoon or early evening tea.

 

Our team fell in love with the cute design of KOHEI's original bag made by Takahashi san and decided to keep it as it is. The drawing represents Takahashi san and his mother who leads family business alongside him, and was based on this photography (see in the picture gallery).
