Chinese medicine incense pouches originated from the “clothing therapy” in Chinese medicine, and folklore once said “wear a herb bag, not afraid of five insect pests”. Wearing an incense bag, although a folk custom, is also a way to prevent the plague. The common use of incense pouches is with aromatic herbs to open the orifice, such as aromatic atractylodes, dahurica, dahurica, calamus, Chuanxiong, aromatic herbs, xinyi and other drugs, containing strong volatile substances. After the jingling season, the climate becomes significantly warmer, flies and insects move, poison rises, and epidemics sprout. The ancients believed that people ate grains and cereals to produce all kinds of diseases, and that illnesses came from the mouth, mostly from evil gas, which was inhaled through the mouth and nose. People in the long-term struggle with various diseases, found that drinking Xiong Huang wine, wearing incense packets can drive away evil and detoxification, its own medical theory. When infectious diseases started to rise in spring, the ancients used Chinese herbal medicine to ensure the health of children by making incense pouches to attach to their lapels and shoulder clothes. Modern research has concluded that the strong fragrance of the herbs in the herbal pouch emits, forming a small environment of high concentration around the body, while the herbal ingredients enter the body through the respiratory tract, the aromatic odor can excite the nervous system, stimulate the nasal mucosa, increase the content of antibodies on the nasal mucosa – secretory immunoglobulins, constantly stimulating the body’s immune system, and promote antibody production. It promotes the production of antibodies, inhibits the growth of many kinds of pathogenic bacteria, and also improves the body’s ability to resist diseases. At the same time, after the drug odor molecules are absorbed by the body, it can also promote the vitality of digestive glands and increase the secretion, thus increasing the activity of digestive enzymes and enhancing appetite. The content of secretory immunoglobulins on the nasal mucosa of children is low and they are prone to upper respiratory tract infectious diseases, so they are most suitable for wearing scented capsules. Let children often put the scented bag in their pockets, pillow, for the flu, diphtheria, chicken pox, epidemic meningitis, measles and other infectious diseases have a certain degree of prevention and auxiliary therapeutic functions.
