Jingwei Fu tea belongs to the category of black tea and post-fermented tea. Theoretically, Fuzheng tea has the effect of improving sleep, but Jingwei Fuzheng tea is made of sun-dried green tea in southern Shaanxi, and the caffeine content of Fuzheng tea made of this raw material is slightly higher. Therefore, it is suggested that if you want to improve your sleep, you can try to drink Gudu Fuzheng tea, using black tea as raw material, but the effect of helping you sleep is still good. However, the price is relatively more expensive than Jingwei Fuzhou Tea.
