Pregnant women can drink Jiang Shui. There is a folk saying that "eat radish in winter and ginger in summer". Ginger is a popular seasoning for people. It is not only used for food, but also used for medical care and health preservation, which has a long history in China. In Compendium of Materia Medica, Li Shizhen, a great physician in the Ming Dynasty, once praised ginger as "pungent but not meaty, eliminating evil and avoiding evil, producing light cooked food, frying it with vinegar, sauce, bad salt and honey, and blending it, all of which are not inappropriate, but vegetables can be mixed, fruits can be used as medicine, which is beneficial to the fight." Traditional Chinese medicine believes that in summer, the yang in the human body goes out and the belly is relatively cold, so eating ginger properly in summer is beneficial to human health.
