Chinese medicine pays attention to three-point treatment and seven-point treatment. All the discomforts in our body are caused by the obstruction of meridians, and the main reason for the obstruction of meridians is the dampness and cold in the body. The essential oil extracted from Beijing Tongrentang contains the extracts of Caulis et Folium Gaultheriae Yunnanensis, Radix Angelicae Pubescentis and Folium Artemisiae Argyi, which is a specific medicine for eliminating dampness and dispelling cold. Combined with modern high-tech pure extraction of small molecules technology and drug nano-penetration technology, it has strong pertinence, strong penetration and effective absorption. As long as the dampness and coldness in the body are eliminated and the meridians of the whole body are unobstructed, the root cause of the disease can be naturally removed. In addition to essential oil therapy, we need to pay more attention to living habits and eating habits in the later stage to prevent dampness and cold from entering the body again.
