Function
Grape skin extract has the effect of promoting intestinal movement. Resveratrol in grape skin is also a strong antioxidant. It can effectively whiten skin, prevent skin aging, and improve physical condition. Eating some grape skin properly can absorb a large number of vitamins and proteins in the grape skin, which can provide energy for the body, and has a certain preventive effect on cardiovascular and cerebrovascular diseases.
Grape anthocyanins can relax ciliary smooth muscle, thereby relieving visual fatigue, improving dark light adaptation, and increasing retinal blood flow in glaucoma. It was found that anthocyanins of grape skin can promote the resynthesis of rhodopsin in the dark, enhance night vision, and can be used in the treatment of night blindness and diabetic retinopathy.
