The method and dosage of herbal decoction for kidney deficiency in clinical practice are related to the condition of the patient as well as the texture of the herbs used, and there is no clear method and dosage. 1. The texture of the herbs: Clinical patients with kidney deficiency mostly use tonic drugs. If the formula contains ores and shellfish, the decoction time is relatively long, such as keel bone and oyster, etc. If the formula contains flowers, it needs to be decocted in a packet and then placed under the bottom, such as cyclamen and roses, etc. If the formula contains valuable herbs, such as antler velvet and rhinoceros horn, etc., it is necessary to decoct the herbs individually. 2. Condition: The dosage of traditional Chinese medicine is mostly related to the factors of the condition and the efficacy of the medicine. Some of the medicines may be increased in dosage if the condition is acute. In short, the method of decoction and dosage of traditional Chinese medicine for kidney deficiency should be operated under the guidance of professional physicians, and should not be blindly decocted by oneself to avoid adverse consequences.
