2. The Huangdi Neijing said: "The Yin in May also prospers the Yang, and the Yin in May also prospers the Yang, and the Yang declines in May." Because May is the month when the yang is soaring, it is precisely because the yang is starting to soar this month that the anode produces yin. Therefore, although the yang in May is very strong, there are signs of decline, so it is said that the yang in May is declining. At this time, the body's resistance is the weakest, so some infectious diseases often occur, such as hand, foot and mouth disease, eczema and gynecological diseases.
3. From the perspective of western medicine, in the fifth month of the lunar calendar, the five poisons gather, and poisons such as rats, insects, snakes and ants begin to lay eggs and grow, and bacteria and viruses also begin to explode at a high speed. This is because the temperature in May of the lunar calendar and the accumulated humidity in the rainy season are suitable for the infection of bacteria and viruses. From the perspective of traditional Chinese medicine, it is: May is coming, the weather is dry, the five poisons are rampant and restless. It is a season in which wind, cold, heat, humidity, dryness and fire coexist, and it is the season that can most affect human health.
4. In addition, May is also called "Five Poisons Month", not only in the fifth month of the lunar calendar, but also because May is the time when people widely spread the "Five Poisons" such as scorpions, poisonous snakes, centipedes, toads and geckos, so there is a folk saying: "Dragon Boat Festival, the weather is hot, and the five poisons wake up and there is no peace."
Every year at noon of Dragon Boat Festival, the five poisons begin to be born, so people will sprinkle lime, spray realgar wine and burn medicinal smoke in corners and all shadows before noon to kill the five poisons and drive away the foul air. At the same time, they will sweep the dust and garbage outside and clean the room.
According to Chinese medicine, there are many toxins in our bodies. Any substance that can not be excreted in time and will have adverse effects on our body and spirit can be called "poison", such as blood stasis, phlegm-dampness, cold, food stagnation, qi stagnation, excessive internal heat and so on. Pay attention to health in May to prevent these toxins from deteriorating in the body. A clean diet is beneficial to people's long-term health.
