The auxiliary ingredients in Chinese medicine poultice are mostly food, such as lotus seeds, yam, walnut meat, red dates, aconite, honey, barley rice, rock sugar, etc., which are appropriately chosen, sweet and delicious, beneficial to human body, and children also like to take them, which can achieve the combination of medicine and food tonic. In modern medicine, it has the function of regulating immunity and enhancing the immune function of human body. It is mainly for some chronic diseases and weak subhealthy people, with the advantages of smaller dose, easy to take for a long time, palatable and high bioavailability. Therefore, it is especially suitable for children with chronic diseases and weaknesses in pediatrics, who need long-term Chinese herbal medicine. Qin Bowei, a famous doctor in modern times, said, “Ointment is not a mere tonic, but contains the meaning of saving bias but disease.” Therefore, the cream formula is different from other tonic prescriptions, it has the characteristics of treatment in tonic, treatment in tonic, and combination of tonic and treatment. Some people are concerned about whether the long-term use of poultices, which are mostly tonic medicines, will affect the growth of children’s bones or cause premature sexual maturity. According to the physiological characteristics of children are different from those of adults, children are vigorous and energetic; in general, it is not appropriate to take tonic. Whether it is a dietary supplement or a medicinal supplement, caution should be exercised. Once there is a disease, the main focus should be to cure the disease, the disease is well, recovery is also faster than adults. If you pursue highly nutritious food, or use tonic drugs, not all of them are beneficial. However, some sick children with weak constitution, low immunity and weak function of internal organs have poor repairing ability of the body itself, so proper supplementation is beneficial for health recovery. Such tonic should be prescribed by a physician with rich clinical experience, through careful examination of the child’s detailed situation, under the guidance of the holistic concept of Chinese medicine, so that the prescription of Chinese herbal medicine is essentially different from “children’s tonic” and is beneficial to the body. In particular, we should pay attention to the physiological characteristics of children’s “form and gas are not yet full, the internal organs are not yet firm, the couples are loose, and the surface guard is not solid” and “children’s lungs, spleen and kidneys are insufficient”. Any internal and external environmental stimuli or changes in life and living can lead to illness in children. For example, some children have recurrent respiratory infections or coughs, others are thin and yellow, short in stature, and have poor appetite. Some children are prone to repeated external infections, poor immune function, vomiting, diarrhea, lack of digestive capacity, easy to feel a variety of infectious diseases, the need to target the internal organs of the lungs, spleen, kidneys and other organs of children to tonic, distinguish their yin and yang deficiency real hot and cold, for the treatment of lungs, spleen and kidney. The prescription of paediatric ointment is formulated for the weaknesses of children’s endowment, delicate internal organs, infantile Yang, infantile Yin and so on, combined with different physical conditions of children, comprehensive past medical history and physical status to cubic dispensation of medicine, adjusting the internal organs of children’s Yin and Yang, Qi and blood, eliminating phlegm, stagnation and food accumulation. However, the physiological characteristics of children are often inadequate in the spleen and stomach, and the digestion and absorption of creams also depend on the normal functioning of the spleen and stomach, so the clinical use of drugs must be carefully taken care of. Doctors’ prescriptions often use Si Jun Zi Tang, Ginseng and Bai Zhu San, Yu Ping Feng San, etc. as the basic formula for pediatric poultices, which are calm and well-matched, edible and medicinal, and focus on regulating the spleen and stomach. The formula is then formulated according to the internal organs, qi and blood, yin and yang, as well as phlegm and dampness, food accumulation, heat and stagnation, etc. The medicine should be warm but not dry, cool but not biased, tonic but not stagnant, nourishing but not greasy. Avoid attacking, dispersing and poisonous products, so as to avoid adverse reactions and toxic side effects. Therefore, Chinese medicine cream prescriptions emphasize individualization and strict identification, and the prescriptions are chosen to be calm and not biased. Chinese herbal poultices are easy to store and should be stored in a refrigerator below 10℃ for a long time, but not frozen. Pay attention to check, if there are bubbles, mold, odor, it is not suitable to take again. It should be known that such treatment is not visible in 3~5 days, but needs to be taken continuously for a long period of time. The traditional intention of poultices is to be calm, slow and long-lasting, so it is appropriate to take Chinese poultices in this case. The characteristics of herbal poultices are easy to take, convenient to store, one for one, and long term. It is best to start with a small dose of cream, about 10 ml of l tablespoon every morning, melt with boiling water, and take it on an empty stomach, and then add one more time at night before going to bed after 1 week of taking. The main purpose is to let the stomach and intestines have a process of adaptation, but also to observe the adverse effects of drugs. In addition, you also need to cooperate with dietary regulation, and do a combination of work and rest, moderate exercise, so as to make the cream formula to play the best role. It is also important to take it correctly to get the desired effect. It is not recommended to take paediatric prescriptions in the acute stage of the disease, such as fever, vomiting, diarrhea, sore throat, cough, frequent urination, etc., should be taken after the cure or basic relief. If you are in a hurry to adjust the tonic during this period, not only will it not play a good role in adjusting the tonic, but also have the suspicion of staying behind closed doors. When taking the cream, avoid cold, spicy, greasy, indigestible and strongly stimulating food, so as not to hinder the digestive function of the spleen and stomach and affect the absorption of the cream. At the same time, avoid eating pickled food such as radish and mustard, so as not to hinder the absorption of qi tonic drugs such as dang ginseng, and avoid pig and sheep blood and iron; in addition, it should not be taken with milk, because the calcium, phosphorus, iron and other substances contained in it and organic substances in tonic drugs are prone to chemical reaction, generating compounds that are difficult to dissolve. In case of other diseases or the need to combine with other drugs, under the guidance of a physician, you should follow the medical advice whether to stop taking or continue to use the cream.
