PROPERTIES OF SENCHA Sencha is recommended as a morning drink, since its early-picked leaves have an extremely high level of stimulating caffeine and sencha is known to speed up metabolism. Just like other Japanese green teas, it is not only a rich source of catechins but also one of most powerful natural antioxidants. Drinking sencha helps in slowing down the ageing processes, getting rid of toxins, reducing bad cholesterol, keeping sugar levels in check and improving dental health. Its leaves contain easily absorbable vitamin C, beta carotene, folic acid, potassium, calcium and phosphorus. Just like matcha tea, sencha is a well-known mood-booster.
