Some proprietary Chinese medicines and pCms can be taken together, but it is necessary to consider whether they can be taken together according to the actual condition, the composition of the medicines, and so on, and it is not possible to make a generalization. Illness has a greater impact on the combined use of pCms and TCMs. Some proprietary Chinese medicines for treating colds cannot be taken together with tonic proprietary Chinese medicines, such as wind-cold and cold particles, which suggests that they cannot be taken together with tonic proprietary Chinese medicines. Moreover, there may be contraindications for compounding between proprietary Chinese medicines and proprietary Chinese medicines, for example, proprietary Chinese medicines with ginseng cannot be taken together with proprietary Chinese medicines containing wulin, such as ginseng solid pill cannot be taken together with preparations containing wulin, quinine and other drugs. For the efficacy of similar, use together does not affect the efficacy, there is no clear contraindication of proprietary Chinese medicines can be combined under the guidance of a doctor.
