Do not use boiling water for Chinese medicine
Traditional Chinese medicine is often one of the most trusted medicines, and decoctions are also the most widely used clinical forms.
Although it is inconvenient to carry, but has small side effects, it has good efficacy and is still used by people.
However, the traditional Chinese medicine has some strict requirements for the medicinal effect of the decoction. After the decoction can no longer be cooked, the medicinal effect of the Chinese medicinal materials will be gradually lost. Therefore, attention should be paid to the decoction method.
In order to improve the efficacy of the decoction, the traditional Chinese medicine decoction method has always been particular about. For example, Li Shizhen of the Ming Dynasty said: “Even though the decoction of all things is special, the practice is as good as the decoction.Degree, the medicine is also useless. ”
Xu Lingtai, a medical scientist in the Qing Dynasty, also said, “The method of decocting medicine is the best to say deeply, that is the effectiveness and inefficiency of the medicine.
“In order to improve the efficacy of the decoction, the decoction of Chinese medicine must be proven.
Some people are accustomed to soaking medicinal materials with boiling water before frying Chinese medicine. They think that this not only shortens the cooking time, but also effectively decomposes and dissolves Chinese medicine. This is actually a lack of scientific understanding and Chinese medicine cannot be boiled in boiling water.
The protein contained in traditional Chinese medicine will solidify due to sudden heating due to boiling water. The staggered cell walls will harden, and the outer layer will form a tight cell membrane, preventing the inner body from fully dissolving.
The polymer substances contained in traditional Chinese medicines tend to form colloids when they encounter boiling water, which is also not conducive to the exudation of active ingredients.
When the traditional Chinese medicine is cut and pulverized, the powder left on the surface is gelatinized due to sudden heating, which prevents the medicinal materials from being inserted into the channel, making it difficult for water to penetrate into it, and it is difficult for the ingredients to disperse after decomposition, which ultimately affects the decomposition of the ingredients.
Aromatic Chinese medicines, such as mint, perilla, bougainvillea, amomum, cardamom, etc., contain volatile oil and volatile substances, which are volatile when heated. Avoid boiled water and avoid boiling water.
In general, cold water is usually used for soaking for about 30 minutes before decoction. However, some experiments suggest that the optimal water temperature for soaking before decoction is 40 ℃.
At 50 ° C, this condition not only makes the medicinal materials moist and fully expand, but also improves the frying rate of the active ingredients.
