Traditional Chinese Medicine Guide

clinical application of Chinese medicine decoction is the earliest and most extensive forms. Their adaptation of BRC, the principle of addition and subtraction with disease, but also has convenient preparation and rapid absorption characteristics of markedly more closely followed the favor of doctors and patients.
However, with bags of Chinese medicine, often make people confused, this introduces you to the knowledge of some medicinal preparations.

one, medicine or apparatus used
Decoction of quality and choice of medicine or device has a close relationship. Still is a casserole as well as casseroles, materials and pharmaceutical ingredients stability will not be a chemical reaction, heat evenly to ease, and this is one of the reasons used since ancient times. In addition, optional ceramic pot, stainless steel frying pan and glass device. But not use of iron pots, copper pots, mainly because of iron pots or brass pot of chemically unstable, easily oxidized. When in the decoction medicine and traditional Chinese medicine contains chemicals that react with the tannins as can generate tannic acid composition of iron, so that the color of liquid to deepen. Flavonoids can be generated with capacitive polymer difficult. Organic acids can be generated with the salt. These will affect the quality of decoction is directly related to the clinical effect of decoction of Chinese medicine.

Second, medicine or the amount of water
medicine or the amount of water is also very important, plus the amount of water directly affects the quality of decoction. Less water, cause drugs are not thoroughly boiled, leaching of active ingredients not completely. More water, boiling out of liquid and more inconvenient for the patients taking the medication. Chinese herbal medicine because of its different texture, it is also a greater difference in water absorption is generally 5-10 times the amount of water control. The weight of the same drug, its volume on the loose texture of large amount of water absorbed naturally over. Solid texture, its size on the small amount of water absorbed little. Therefore, the boiling flowers, leaves, whole plant drugs, we should add more water. Boiling mineral class, shellfish drugs, amount of water to less. According to the traditional method of adding water, is the drug into the pot, the first increase in boiling water to the surface 3-5 cm of water over drugs, plus a second boiling water to the surface of 3 cm prevail over drugs. This method of adding water, simple, and very easy to grasp.

3, decoction of Attention

1, medicine or pre-soaking

drugs must be soaked before boiling, because the medicine comes from the plant is dry and more products, medicinal herbs by soaking in the water can soften tissue swelling resume its natural state, preparing medicine easy and effective when component leaching. Generally flowers, leaves, stems and class-based drugs, soaking for 1-1.5 hours. To roots, seeds, roots, fruit-based drug soaking for 2-3 hours.

2, boiling number

to repeated boiling boiling than the first time the effect is good. Practice has shown that a decoction decoction decoction twice to about 80% of the components, so the number of medicine or to two or three suitable.

3, decoction of temperature

decocting temperature level, the Chinese called “better” general custom is called “slow fire” or “武火.” The so-called slow fire, the fire is weak, the temperature rising slowly evaporates slowly. The so-called 武火 is strong fire, the temperature rises rapidly, water evaporation is also fast. Such as medicine or when the degree of heating is too strong, fast water evaporation will affect the leaching of active ingredients, are easy to paste pot. Conversely, the weak level of attainment, boiling the drug effect he sent. Generally is not used 武火 before boiling, to boil and then switch to a slow boil to keep the micro-state, can slow down the evaporation of water, it is a good active ingredient decoctions.

4, boiling time

mainly based on the nature of drugs and diseases, and drug conditions. Generally start from the first fry need to boil for 20-30 minutes, 30-40 minutes for the second frying. Treatment of influenza drugs, the first 10-15 minutes of frying, the second fry for 15-20 minutes. Tonic drugs, the first 30-40 minutes of frying, the second fry 40-50 minutes.

5, sacrificing liquid volume

generally refers to a drug after two boiling liquid volume after the merger. Adults take 400-600 ml, taken twice a day. Children take 200-300 ml per day taken in two or three.

6, methods of medication

general, after a merger of the two drugs boiling liquid, taking in two. Children can be divided into 2-3 doses. Treatment of colds, fever, enteritis, diarrhea medicine, the method can be applied frequency service, that service once every 4 hours, each taking 30-40 ml, recovered basis, and then to 2-3 times daily service, to a small number of children as well.

7, special medicine decoction

doctors under the condition of the patient and the nature of the drug, in prescribing a drug with a footnote.
(1) first decoction:

usually some minerals, shells, angle A drugs, because of its hard texture, not easy to fry the active ingredient, generally Xianjian 30-40 minutes, then boiling the mixture with other drugs. Common with gypsum, raw keel, pearl, raw sienna and so on. Otherwise toxic drugs Xian Jian, a long time to fry up to attenuated or drug purposes. Aconitum drugs such as long-fry can aconitine aconitine decomposed into the original base, its toxicity is only the original 1 / 2000. Long as aconite decoction can increase not only reduce the toxicity of cardiac function.
