There is a folk custom of "eating lotus roots in summer" in China. As early as the Xianfeng period of the Qing Dynasty, lotus root was designated as a tribute to the imperial cuisine. Traditional Chinese medicine believes that raw lotus root has the effects of clearing away heat and promoting fluid production, moistening lung and removing blood stasis, reducing swelling and stopping bleeding, and can be used to treat fever, polydipsia, vomiting blood and gonorrhea. Cooked food has the effects of strengthening the spleen and stomach, promoting digestion and stopping diarrhea, and solidifying essence.
The third treasure of summer solar terms is mung bean sprouts. Eating mung bean sprouts often can clear the stomach, clear away heat and toxic materials, remove damp heat and clean teeth, which has a good health care effect. Clinically, mung bean sprouts decoction is used to treat traumatic infections such as furuncle and scald. Riboflavin contained in mung bean sprouts can be used to treat oral ulcers, regulate five internal organs, dredge meridians and relieve toxins, and can be used for excessive drinking, damp-heat stagnation, anorexia and physical weakness.
Mung beans: Mung beans are sweet and cool, and have the effect of clearing heat and detoxifying. In summer, people sweat a lot, body fluids are lost, and the electrolyte balance in the body is destroyed. It is the most ideal way to supplement it with mung bean soup. It can not only clear away heat and relieve summer-heat, replenish qi to quench thirst and induce diuresis, but also replenish water and inorganic salts in time, which is of great significance for maintaining water-liquid electrolyte balance.
In the past, there was a folk custom of "eating new things in summer", that is, after the summer heat, farmers tasted new rice, ground the newly cut rice into rice, and prepared to worship the food of the five grain gods and ancestors, and then everyone tasted new wine. It is said that "eating new things" means "eating new things", which is the first new day after the summer festival. Cities generally buy a small amount of new rice for cooking in old rice, plus newly listed vegetables. Therefore, there is a folk saying that millet is eaten in summer and grain is eaten in summer.
