Synopsis
Source of validity: Traditional
Rating (out of 5): 1
Kukicha, also known as twig tea, is a Japanese green tea made from the stems, stalks, and twigs of the tea plant (Camellia sinensis). Its use for stress is primarily supported by tradition rather than robust scientific evidence. In Japanese culture and macrobiotic dietary practices, Kukicha is considered a gentle, low-caffeine beverage believed to promote relaxation and balance due to its mild flavor and purported alkalizing properties. This traditional use aligns with the general notion that warm, non-stimulating herbal teas can provide comfort and aid in stress reduction through ritual and relaxation, rather than through direct pharmacological action.
However, scientific studies specifically investigating Kukicha’s effect on stress are lacking. While green teas contain the amino acid L-theanine, which has been shown in clinical studies to promote relaxation and reduce stress, Kukicha contains less L-theanine than traditional green tea leaves, as it is made primarily from twigs and stems. Therefore, any calming effect is likely to be less pronounced. There are no clinical trials or strong scientific data directly supporting Kukicha’s use for stress beyond the general relaxing effects associated with drinking warm, non-caffeinated teas. For these reasons, the evidence rating for Kukicha's use in stress is low, and its use is justified more by cultural and traditional practices than by scientific validation.
