“The breeze has no power to butcher the heat, the sunset with wings flying up the mountain. The people have been exhausted by the river and the sea, but the sky is not shy of the river and the Han dry?” This poem by the poet Wang Ling of the Song Dynasty is a perfect description of the scorching climate of the three days of the sun. It is because nature is hot that people use ingenuity and ingenuity to weave unique health practices, such as drinking mung bean soup, preparing patchouli water, and eating lotus seed congee, and so on, and they continue to do so today. The three days of the year can be considered the most unpleasant days of the year. On the one hand, this is the highest temperature day of the year, the heat is unbearable; on the other hand, this is just before the rainy season, the rain constantly, resulting in heavy dampness, so Chinese medicine has “summer more than the wet” said. Therefore, at this time both hot and humid, folk have “small summer heat, the big summer, the upper steam under the boil” saying. At this time, the sun shines on the top and the dampness evaporates on the bottom, which makes people suffer a lot. They have to endure the hot sunlight and sweat, but they also have to endure the dampness and get tired, especially the heat and dampness that trap the spleen and stomach and make people have the phenomenon of “resistance to summer”. Resistance to summer – loss of appetite, tiredness of limbs, sticky mouth and tastelessness. What is more unfavorable is that heat and dampness are opposite in nature: heat is yang, which causes people to open their pores and sweat more than once and lose fluids; dampness is yin, which obstructs the qi flow and easily damages the body’s yang energy. So this is a contradictory community, in the prevention and treatment of such as to lift the summer heat is bound to bitter cold damage Yang, such as to get rid of dampness is bound to bitter warm dry loss of fluids. Therefore, the correct method of health care is very important to spend three days of volcanoes. The following points should be mastered: 1, both to clear the heat and to protect the yang. The summer heat, summer heat, sweating more than, often make people feel annoyed hot dry mouth. Therefore, avoiding heat and thirst is a natural behavior. Blowing cold air conditioners and drinking ice-cold beverages have become commonplace in summer, but this is often accompanied by damage to the body’s yang energy, especially the spleen and stomach yang energy, and people often suffer from stomach pain and diarrhea. Therefore, summer in the summer to avoid the summer to quench thirst at the same time should avoid too cold, so as not to damage Yang Qi. 2, both to resolve the summer dampness and to protect the yin liquid. Summer heat and humidity plague the human body, especially the spleen and stomach, resulting in dysfunction of the spleen and stomach, loss of appetite, tired limbs, and even diarrhea and vomiting, so the summer heat and humidity is an important rule of health care in summer. But the problem is that the dampness medicine is often warm, dry and aromatic products, easy to lose the body’s yin liquid. This requires the summer in the dampness of the summer at the same time must protect the body’s yin. 3, pay attention to clear the mind and calm the mind to remove annoyance. The hot summer climate often makes people irritable, restless and restless. This requires the application of some food and drugs that can calm the mind, clear the heat and remove annoyance. In folklore, the custom of taking mung beans and lotus seeds on the day of three volcanoes is often passed down in some areas, and patchouli preparations are commonly used in the summer season. This is because the performance and functional characteristics of mung beans, lotus seeds and Huo Xiang Zheng Qi preparations correspond to the climatic characteristics of summer. Mung beans are known as the “holy grail of summer heat protection”. It is sweet and cold in nature, and belongs to the heart and stomach meridians, with the effect of clearing heat and eliminating summer heat, diuretic, and relieving irritation, making it ideal for summer consumption, both to directly relieve summer heat and to make summer heat go away from the urine. You can boil mung beans with a small amount of rock sugar into soup and eat it after it cools down to relieve summer heat and quench thirst. There is a popular proverb: “If you want to avoid insomnia, cook porridge with white lotus.” The white lotus here refers to lotus seeds. As the mature seeds of the aquatic plant lotus, lotus seeds are sweet and astringent in nature and have a good calming effect on the mind. There are two characteristics of lotus seeds to tranquilize the mind: one is to nourish the heart and calm the mind. Because lotus seeds are sweet and flat and belong to the heart and kidney meridians, they can nourish the heart and kidney qi upwards and downwards, so that the heart and kidneys can intermingle, which is very effective for insomnia caused by dysfunction of the heart and kidneys (called “heart-kidney disjunction” in Chinese medicine). The second is to calm the mind and tranquilize the spirit. Because lotus seeds are not only sweet but also astringent, they have an astringent effect on the heart and mind, which is especially suitable for summer heat-induced heartburn and insomnia. In addition, lotus seeds have a green germ in the center, the lotus seed heart, which is bitter and cold in nature and has a very good effect in clearing the mind and calming the soul. Therefore, the calming effects of lotus seeds are multifaceted, and their consumption in the summer can really help to calm the mind. Lotus seeds can be eaten alone or cooked with lilies, mung beans and red dates to make porridge or soup. Both mung beans and lotus seeds are medicinal and food products, with a relatively calm nature, good taste and easy to use, and can be eaten in summer to prevent summer heat and cool down the body, to relieve irritation, and to clear the mind and calm the soul. But after all, both are on the cold side, so people with weak spleen and stomach, especially those with diarrhea, should use them with caution. When it comes to summer heat prevention and relief, we have to mention a class of proprietary Chinese medicine – Huo Xiang Zheng Qi preparation. What kind of medicine is patchouli? Why is it so commonly used in summer? The medicinal properties and functions of patchouli are very suitable for use in summer: it has an aromatic smell, is pungent but not harsh, is slightly warm and not dry, and is mainly used in the spleen, stomach and lung meridians, which can not only aromatize dampness, but also relieve summer heat. For vomiting, nausea and diarrhea caused by summer heatstroke, patchouli can relieve dampness, awaken the spleen and stomach, stop vomiting and diarrhea; for colds caused by summer heat and dampness and wind and cold, patchouli can both relieve summer heat and dampness and dispel cold. Therefore, in the heat of summer, whether at home or travel, it is wise to prepare patchouli water.
