Buckwheat tea is made from Tartary buckwheat.
This tea can be consumed by everyone: children, adults, and the elderly, regardless of health status. There is no need to somehow limit its consumption, unlike black or green tea, but we strongly suggest you to check your allergens for buckwheat (it is quite rare to have buckwheat allergy, but still possible).
The most active substance in buckwheat tea is rutin. With regular use, it helps to improve the condition of blood vessels, which improves appearance of the skin and might reduce signs of aging. In addition to rutin, buckwheat contains many antioxidants, vitamins of groups A, B, E, fiber, flavonoids, and protein.
Buckwheat tea cleanses your body, which might help you to lose weight. Moreover, it might help to reduce inflammation and stress, and rejuvenate your body.
