According to the collected results, there are about 1000 kinds of Dai traditional ethnic medicines, most of which are plant medicines, some are animal medicines and mineral medicines, and a few are foreign medicines. Many of them are the same as Han Chinese medicine, but they are different in clinical application. Such as reed seeds refreshing; Cao Kou is used for rheumatism and soreness; Motherwort is used for itching and eczema; Belamcanda is used for menorrhagia. , different from Han Chinese medicine. There are also drugs that are national key protected animals, and there are few sources of drugs, such as hornbill, ivory, peacock hair, wild buffalo gall and so on.

The classification of botanical drugs is generally divided by shape, smell and medicinal parts. The medicinal properties of drugs are generally divided into three categories, namely, hot drugs, cold drugs and flat drugs. The taste of drugs is generally divided into seven kinds: acid, which is mostly used for astringency, antiperspirant and diarrhea; Sweet, mostly tonic; Salty, mostly used for softening and strengthening deficiency; Bitter, mostly used for clearing away heat and toxic materials, removing dampness and relieving pain; Hemp is mostly used for relieving pain, relieving convulsion and eliminating phlegm; Spicy, mostly used to dispel cold and relieve pain; Fragrant, mostly used for refreshing the brain, appetizing and strengthening the spleen. Because the nature of drugs is different and the human body is different, the use of drugs also has its own characteristics. For example, 1 ~ 20 years old is the growth and development stage, and the drug compatibility should be sweet when you are sick; 20 ~ 40 years old is the mature and strong stage, and the compatibility of drugs is sour when you are sick; However, with the gradual aging over 40 to 60 years old, the compatibility of drugs should be salty when they are sick. Another example is to mix different drinks according to different seasons and drink tea with drugs to achieve the purpose of prevention and treatment.

Although the prescriptions in Dai medicine are not as strict as those in traditional Chinese medicine, most of them use relatively fixed compound prescriptions composed of several drugs when treating diseases. These prescriptions are summed up in the long-term practice of fighting diseases. In the treatment of diseases, through the increase or decrease of drugs, the effect of treatment is observed and gradually screened. The prescriptions used range from two or three drugs to dozens of drugs; Some have multiple treatments, while others have multiple symptoms. The four "Yata" caused by the imbalance of wind, fire, water and soil, namely Wayota, Diezhuo, Apota and Batawita, are all composed of fixed drugs, which Dai doctors call "Yata".

This formula theory is called "Yata is good".
