Chinese medicine decoction method
1. Does the Chinese medicine need to be cleaned before boiling?
Most Chinese herbal medicines are raw medicines, which are usually processed and processed before being sold. There is usually no need to wash them before boiling. If you feel that the herbs are dirty, you can rinse them with water quickly before soaking. Do not soak and rinse them to prevent the active ingredients that are easily soluble in water from being lost, thus affecting the efficacy of traditional Chinese medicine.
Second, Chinese medicine decoction should choose those utensils?
The decocting utensils are generally made of earthen jars and casseroles. Enamel and stainless steel can also be used. However, aluminum, iron and copper are not allowed to be used to prevent these metal objects from reacting with drugs, affecting the efficacy of the drugs and even causing harm to the human body. Li Shizhen once said: "Where the decocting and avoiding the copper iron, it is advisable to use silverware jars." Now generally used is a covered ceramic casserole.
3. What is the cooking procedure for Chinese medicine?
1 Soak the medicine into the pot and flatten it, then add cold water to the level of the medicine, soak for 0.5-1 hour. If you use 20-30 degrees warm water to soak in winter, you can shorten the boiling time, but you can't use boiling water to avoid the protein in some plant cells being suddenly solidified by heat, the outer layer forming a tight coating, or some high molecular substances. The colloid is detrimental to the leaching of the active ingredient. However, the soaking time should not be too long, especially in the summer, so as not to cause drug enzymatic hydrolysis and soaking before soaking.
If there are more flowers in the square, the water absorption is larger, and water should be added before boiling to make the water higher than the medicine plane by about 1-2 cm.
2 heating heat generally use the fire (quick fire) before the medicine is boiled, and should be changed to simmer (slow fire) after boiling. However, some traditional Chinese medicines for treating exogenous diseases can also be simmered after boiling for more than 5 minutes.
3 decoction time should be based on the nature of the drug and disease, the difficulty of dissolution of the active ingredients and the use of drugs. Generally speaking, it takes 20 to 25 minutes for the head to boil to start the calculation, 15 to 20 minutes for the second to fry, 10 to 15 minutes for the decoction, and 10 minutes for the second. Nourishing head boiling for 30 to 40 minutes, two boiling for 25 to 30 minutes, first decoction must be fried for 10 to 30 minutes, after the medicine should be 5 to 10 minutes after the Zui into the pot.
After the second frying (re-fried) head frying, the drug juice is filtered out, and the cold water is added again to about 0.5-1 cm above the medicine plane. Continue to boil and boil until it is boiled for 15-20 minutes.
Fourth, on the first fried, after the next, package fried, blunt, sputum, etc. (1) first fried
The purpose of frying first is to increase the solubility of the drug, reduce the toxicity of the drug, and fully exert its efficacy.

3 Some botanicals: such as scorpion yellow, hemp seed, sarcophagus, only effective first.
(2) after the next
The purpose of the latter is to reduce the loss of volatile oil and to protect the active ingredients from decomposition and destruction.

3 pairs of fluffy drugs, such as invertebrate, etc., take the package frying, can avoid the fluffy hair falling into the soup to stimulate the throat, causing cough.
(4) Smashing into
For some gums or sugars, the viscosity is large, such as gelatin, staghorn gum, honey, sugar, etc., should be added with appropriate amount of boiling water, then rushed into the soup or into the soup to take it. If mixed, it will cause the viscosity of the liquid to be large, affecting the dissolution of other ingredients, and the glue will suffer some loss.
(5) Decoction water
Generally, bulky drugs with large water absorption, such as loofah, stove heart, money grass, japonica root, etc., should be boiled with water, and the obtained juice will be decoctioned and then fried.
(6) melting
Such as Glauber's salt, Xuan Ming powder, etc. can also be melted into the soup application

5. Should a Chinese medicine be cooked several times?
In general, the active ingredients contained in a Chinese medicine after being boiled twice have been greatly reduced, so it is better to cook twice. However, for prescriptions with a large dose, there may be more active ingredients remaining after two decoctions, which can be fried for the third time and changed to 3 times a day to save Chinese medicine resources and at the same time improve to a certain extent. Efficacy.
