Secondly, ginger should be removed. Because eating ginger at night is against the normal principle of yin and yang. At night, the yang qi begins to converge and the yin qi rises, so you should rest and nourish your essence at night, while ginger is pungent and warm, containing volatile oil, which has a divergent and upward effect. (But if you are a woman with spleen and stomach deficiency and cold, drinking a small amount of brown sugar and Jiang Shui at night is more conducive to dispelling cold and removing dampness, keeping warm and raising qi. )
