很多人以为中药煎得越浓效果越好。其实,这样的认识有失偏颇。煎中药是将中药中的有效成分不断释放、溶解的过程。如果有效成分已经溶解释放到药液中后,还连续不断地煎煮,反而会让药液中的非有效成分(树脂、树胶、色素等大分子化合物)不断溶出,可能使有效成分遭到破坏,导致药效降低。 Many people think that the more concentrated the better, the better. In fact, such understanding is biased. Fried Chinese medicine is the active ingredient in Chinese medicine continue to release, dissolve the process. If the active ingredient has been dissolved and released into the medicinal solution, it will be decocted continually, which will cause the ineffective ingredients in the medicinal solution (such as macromolecular compounds such as resin, gum and pigment) to be continuously eluted and the active ingredients may be destroyed , Resulting in lower efficacy.
