What is miasma?

Miasma is a kind of poisonous gas, which mainly occurs in tropical rainforest areas and also occurs in the hot and humid areas in southern my country. Miasma refers to a poisonous gas formed when the bodies of animals and plants die without being buried and are exposed on the surface, and are decomposed by microorganisms. Miasma often occurs in winter and spring. People who go into the mountains for activities need to be careful, as people who are invaded by miasma are likely to develop malignant malaria.

Miasma was a common disease in the ancient Zhuang area. Guangxi has long been known as the "Malaria Town". As it was said in "Guihai Yuhengzhi": "Malaria is not found in Guilin in Guangdong and Guangxi. From there to the south, all places are miasma towns." Guangxi's hot, rainy and humid climate is the main cause of miasma. Zhuang doctors in the Song Dynasty not only had some understanding of the causes and pathogenesis of miasma, but also made a preliminary classification and used local prescriptions and medicines for treatment. The miasma mentioned by Zhuang medicine includes many diseases and does not refer to a specific disease. Therefore, "Lingwai Daida" says: "All diseases in the south are caused by Wei's miasma." Zhuang medicine divides miasma into green grass miasma, yellow plum miasma, new grass miasma, and yellow thatch miasma according to the season of onset; and divides it into cold miasma, hot miasma, and mute miasma according to the symptoms and nature. In the practice of fighting against miasma, Zhuang medicine has accumulated relatively rich experience. In addition to the fact that many Lingnan medicines for treating malaria were included in the herbal works of the Tang and Song dynasties, "Lingnan Health Prescriptions" recorded a large number of Lingnan people's experiences in treating malaria, and "Lingwai Daida" recorded the experience of using acupuncture therapy to treat hot malaria in the Zhuang area: "For southerners who have hot malaria for one or two days, they can prick their upper and lower lips with needles... If the malaria has lasted for more than a month and the disease has penetrated into the interior and the patient is on the verge of death, prick the patient's penis and the patient will be cured." Zhuang medicine's understanding and treatment of miasma enriched the content of traditional Chinese medicine. It can be said that it was in the leading position at that time. Miasma in traditional Chinese medicine,

Refers to the toxic gases in the mountains and forests of the south that can cause illness. It mostly refers to the toxic gases generated by the decay of plants and animals in tropical primeval forests.

Miasma: hot and humid air in tropical or subtropical forests. In short, miasma is the poisonous gas generated by the decay of animals and plants in tropical primeval forests. The main reason is that no one effectively deals with the carcasses of dead animals, and the high temperature in the tropics creates favorable conditions for the generation of miasma. Guangxi's climate is mainly tropical monsoon climate, which is hot, rainy and humid, which is the main cause of miasma.

4 Actual miasma: Ancient people had very limited knowledge about miasma, and the actual pathogenic miasma was mostly caused by swarms of mosquitoes. A large number of mosquitoes carrying malignant malaria bacteria gathered together and flew, looking like a ball of dark gas from a distance. When humans and animals are bitten by them, they will be infected with malignant malaria. In movies, we often see people falling down after being surrounded by miasma in the forest. In fact, the miasma is caused by swarms of mosquitoes, and these mosquitoes can spread malignant malaria. The Chinese call malaria "miasma", and in Italian, malaria is called "yin wind", which is exactly the same. There are a few folk songs in Xishuangbanna, China: "Out of ten people who go to Mengla, nine find it difficult to return home; to go to Chefonan, you must first buy a coffin board; to go to Pusaba, you must marry your wife first." These songs vividly describe the harm of malaria to humans.
