It is generally not recommended to take Chinese medicine and western medicine together. Chinese medicines are the active ingredients extracted from traditional Chinese medicines or the broth formed after decoction; Western medicines are usually made by chemical synthesis or extracted from natural products, including organic chemicals, inorganic chemicals and biological products. There may be chemical reactions between the pharmacological components of Chinese medicines and western medicines, as well as a decrease in the efficacy of the medicines. Therefore, it is generally not recommended to take Chinese medicine and western medicine together. Taking Chinese medicines and western medicines together may cause antagonism, reduce the efficacy, or even increase the adverse reactions and cause a series of side effects, as follows: 1. Chinese medicines containing rhubarb should not be taken with western digestive enzyme preparations, as taking them together will affect the activity of digestive enzymes. This kind of Chinese medicine includes Niu Huang Xie Tu Wei Tablets, and so on. 2. Chinese medicines containing tannins, alum and gypsum should not be taken with tetracyclines and erythromycin, as they will cause a precipitation effect and affect the efficacy of antibiotics. This kind of Chinese medicine includes Xianhe Cao, pomegranate skin, oxalic detoxification capsule, and so on. 3. Cinnabar-containing Chinese medicines should not be taken with tribromide, which will generate soluble mercury salts, which will cause mercury poisoning after being absorbed by the body. 4. Hawthorn, schizandra and other organic acid-containing Chinese medicines should be taken with alkaline medicines such as aluminum hydroxide and sodium bicarbonate tablets, which can produce acid-base neutralization reaction and reduce the efficacy of the medicines. 5. Metal ion-containing Chinese medicines such as gypsum and bone marrow can increase the neurotoxicity of aminoglycoside antibiotics, such as gentamicin, if taken together. If you need to take Chinese and Western medicines, you should use them under the guidance of a specialist.
