Chinese medicine is very particular about the decoction and serving method of herbal tonics. A good prescription with accurate dialectic and proper medication cannot be effective if it is not decocted and served properly. Decoction tools: casserole and tile pot are the best. It will not react chemically with the medicine. Iron and copper vessels should not be used because the acids contained in iron and copper can react chemically with the medicine and destroy the quality of the medicine and affect its efficacy. Drug inspection: Open the medicine package, take out the drugs that need to be decocted first, later, stewed or brewed and put them aside, check whether the herbs match and whether there are foreign objects such as clay lumps, hair, iron nails, etc., and put them into the container for soaking after they are accurate. Soaking: In order to give full play to the efficacy of the drug, use pure cold water before decoction, add to diffuse over the surface of the drug, soak for 1 hour, which is conducive to the decoction of the active ingredients of the drug, if the water is added that decoction, certain plant proteins in the drug encounter heat and solidification, the active ingredients are not easy to decoction, affecting the efficacy. Decoction method: Generally, the first decoction of drugs such as shells, minerals (hard texture is difficult to decoct the active ingredients, should be broken first decoction) into a casserole, add an appropriate amount of cold water, cover, first with a martial fire, boiling and then decoction for half an hour; then pour in the already soaked herbs, decoction for 25 minutes, add the next drugs such as mint, sand, etc., decoction for 5 minutes, pour out the juice and put in a water bottle. Do not remove the lid of the pot frequently when decocting to avoid losing the smell. For decoction of superficial, heat-clearing and aromatic drugs, 15 —-20 minutes is enough for urgent decoction; for thick tonic drugs, 30 —–45 minutes is enough for slow decoction on civil fire to make the active ingredients fully exude; for toxic drugs such as aconite and epilobium, long decoction on slow fire can reduce toxicity. Some precious medicines such as ginseng and antelope horn should be stewed separately in order to preserve the active ingredients. Serving method: The proper method of taking medicine can ensure the efficacy of the medicine and reduce the adverse effects of the medicine. Generally speaking, a dose of medicine should be decocted twice and divided into 2 – 3 times; if the condition is urgent, it should be taken at once; the soup should be taken warmly, in addition to sweating and relieving the surface of the body, it should be taken warmly to avoid the wind and to stop sweating; the medicine should be taken 1 – 2 hours before or after meals; nourishing and tonic medicine should be taken on an empty stomach; tranquilizing medicine should be taken before bedtime; patients with fever on time should take the medicine 1 – 2 hours before the fever. Avoidance of medication: certain foods should not be eaten at the same time when taking certain Chinese medicines to avoid the interaction between the two. For example: honey against raw onion; drugs with roasted licorice, roasted turtle nails, etc., avoid eating onion; Poria avoid vinegar; turtle nails avoid kakei vegetables, mint avoid turtle meat; Dihuang, He Shou Wu avoid onion, garlic, radish, etc.. In addition, during taking Chinese medicine should avoid eating cold, greasy, fishy hair things.
