The Chinese Taoists and Japanese Zen Buddhist monks have used Matcha for over 1,000 years as a means of supporting the maintenance of peace and clarity of mind during the long hours of meditation.
Today, we know that e.g. L-theanine, an amino acid concentrated in the leaves used to produce matcha, is responsible for these neuropsychiatric processes. L-theanine stimulates our brain, which affect our mood and evoke a feeling of relaxation and tranquility, without causing drowsiness.
L-theanine helps to induce the state of relaxation similar to the one achieved through meditation. A traditional powdered matcha has four times the contentof L-theanine (39 mg per serving) as compared to green tea served in a bag.
