GABA Oolong

GABA is a unique tea with a high content of GABA - gamma-Aminobutyric acid - an important inhibitory neurotransmitter of the central nervous system. The tea gets its properties as a result of a special production process: the tea is placed for about 10 hours in a special airtight cabinet chamber with the oxygen pumped out and replaced with nitrogen. This tea is produced in Japan and Taiwan.
