Is Chinese medicine worded properly

　　Boil medicine should not cover the lid, not the problem of life habits, different drugs, open cover and cover the effect is different.

　　Some volatile medicinal materials, if open to boil, effective ingredients will be released to the air with water vapor, efficacy will be greatly reduced. This kind of volatile medicinal material is easy to identify, it is xin SAN solution table commonly or balmy change wet kind medicaments, be like mint, su ye, huoxiang, and fry time to should not be too long.

　　Like some tonic drugs such as ginseng, velvet antler, American ginseng, etc., need to slow fry for a long time with a small fire in the container, in order to make its effective ingredients fully cooked out, also should be covered, in order to prevent drug ingredients in slow fry long boil with water vapor lost.

　　And some light weight, large volume of herbs, such as money grass, senna leaves, if the pot is not big enough, cover easily make liquid overflow. Additional, some dissolvable medicinal material, often stirring is needed when suffer, such medicaments had better not cover lid to boil. Of course, it is best to stir along a direction, so that the medicinal materials are heated evenly, so that the effective ingredients are completely dissolved, generally every 10 minutes to turn 1 time.

　　Medicine for good, in the general impression is "begin" to boiling, but some herbs, such as straight ladybell, notoginseng, twotooth achyranthes root, licorice, platycodon grandiflorum later false boiling phenomenon, namely the drug did not reach a temperature of 100 ℃ when began to boil, if the medicine taken off from the fire, no effective components from the medicinal materials dissolve, effectiveness will be affected.

　　Now people boil some "lazy" medicine, open the tap water directly with. Actually, the water of boil medicine cannot graph province trouble, still want to boil the reoccupy after water air is cool, because the tap water of a few places is multi-purpose chloric disinfection, more or less have remain, at the same time the calcium in tap water, magnesium ion is more, also produce reaction easily with chemical compound in crude drug, affect medicinal effect.
