What are the main components of miasma?

The greatest harm of miasma to the human body is that it can cause people to suffer from malaria. Malaria was a disease with a high mortality rate in ancient my country. In recent years, the improvement of medical technology and environmental sanitation has reduced the number of people suffering from malaria and the number of deaths from malaria has also decreased. The main disease that occurs in our country is Plasmodium vivax malaria. Both traditional Chinese medicine and Western medicine are effective in treating malaria. Malaria patients may develop anemia, enlarged liver and spleen, and even die.

The main component of miasma is methane CH4. Methane CH4 can burn in the air and is non-toxic, but the concentration is relatively high and people inside will feel difficulty breathing.

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.

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 doctors includes many diseases, not just one specific disease. Therefore, "Lingwai Daida" says: "All diseases in the south are caused by Wei's miasma." Zhuang doctors divide miasma into green grass miasma, yellow plum miasma, new wheat miasma, and yellow grass miasma according to the season of onset; and divide it into cold miasma, hot miasma, and dumb miasma according to the symptoms and nature. In the practice of fighting against miasma,
