Yao people are best at medicated bath treatment and health care. According to Cong Jiangzhi of the Republic of China, "Yao Ban is so clean, there must be a bath tub at home, so you must take a medicine bath when you come home from work. Because it is deep and clean, there are many people who live long. " For thousands of years, the Yao people like to live in the deep mountains and forests. Because they have little contact with the outside world, it is difficult to see a doctor when they are sick. Therefore, they developed their own medical theory-Yao medicine, and formed their own unique methods of diagnosis, treatment and medication. Yao doctors have a remarkable feature, that is, they are good at preserving health and preventing problems before they happen. How to keep their bodies from getting sick has become the top priority of Yao doctors. In their long-term exploration, they summed up a set of effective methods to keep the body from getting sick, which is Yao medicated bath. They collected natural herbs from hundreds of thousands of mountains, boiled them into potions, and bathed them in hot water to achieve the purpose of preventing and treating diseases.
