Although there are many new preparations of modern Chinese medicine, the most commonly used when seeing a TCM practitioner is still the soup. Because of the specificity of the application of Chinese medicine, tonics have been used for thousands of years because they are easy to add or subtract from the clinical evidence, individualize the prescription selection and use, and have a good oral absorption effect. How to take tonics to ensure good effect? The following factors have a certain influence on the taking of tonics and are worth noting. First, the time and method of taking medicine Generally speaking, taking tonics and eating should be about 1 hour apart, and general drugs can be taken before or after meals. Drugs that stimulate the stomach and intestines should be taken after meals, tonic drugs should be taken on an empty stomach, malaria drugs should be taken 2 hours before an attack, tranquilizers should be taken before bedtime, drugs for menstrual pain should be taken 3-5 days before menstruation, drugs for fever and cold should be taken at 9-10 p.m. For acute serious illness, there is no time limit and can be taken at any time. After a dose of medicine is decocted twice, the juice is blended and divided into 2-3 doses, which can be taken once in the morning, once in the middle and once in the evening, or divided into morning and evening. For acute intestinal obstruction, such as abdominal pain, dry stool, or vomiting, the decoction can be taken once. There are also people who take more than 3 times a day, such as those who have a high fever that does not subside, they can be given an antidote, taking 1 dose in 4 hours, regardless of day and night. There are also 2 doses a day to enhance the power of medicine. Second, warm or cold soup is generally used to serve warm, because warm will not stimulate the gastrointestinal, in order to facilitate the absorption of drugs, especially in the morning after taking drugs on an empty stomach. Some drugs are more emphasis on warm or hot, such as fever, chills, headache, etc., to give relief drugs warm or hot, conducive to sweating and relief of the surface, to achieve the purpose of sweating out the evil go. Therefore, it is often necessary to drink hot porridge to reconcile the stomach gas and help sweat out the evil to enhance the medicinal power. In addition, the spleen and stomach deficiency cold or spleen and kidney deficiency cold patients more appropriate to take hot, so as to avoid cold medicine folded Yang Qi. In the case of cold and damp paralysis, hot medicine is good for warming the blood vessels, dispersing cold and removing dampness. Some diseases can be served cold, such as vomiting, cold can reduce vomiting; some heat detoxification drugs are stronger when served cold. In the complex process of pathological changes, only through the special method of taking drugs, in order to adapt to the needs of the disease. For example, in the case of typhoid fever, “false heat and real cold”, the method of “hot medicine taken cold” should be used to adapt to the transformation of the disease. Conversely, such as “true heat and false cold”, the application of “hot cool medicine” method. If not handled in this way, the phenomenon of drug resistance often occurs when the medicine is vomited in the mouth, and the therapeutic effect is not achieved. This is a kind of anti-correction in the treatment of Chinese medicine. The first decoction is mixed with the second decoction or not, and finished at once. It is often used for some critical illnesses, such as Yangming disease, dryness, solidity, gangrene and fullness, so that the drug can reach a high concentration in the body in a short time, thus producing therapeutic effects. However, because the concentration of the drug drops quickly, the therapeutic effect cannot last, so it is generally not used. Frequent dosing refers to a small amount of multiple doses, with a short interval between doses and a high frequency. Frequent dosing is often used to treat vomiting, and for those patients with severe coughs that even cause vomiting, cough medicine can also be taken frequently. Children taking tonics often vomit, and it is appropriate to use frequent doses. Patients who are in a coma from a stroke can take the medicine several times with a cotton swab. Frequent doses are used to achieve therapeutic effects through the accumulation of drug concentrations in the body.
