We talked about the possible toxicity of all kinds of medicine. It is the dosage that makes a substance either medicine or poison to our bodies. This concept applies not only to Western medications but also to Chinese herbal medicines. People seeking medical treatment may be diagnosed by a Western medical doctor and a TCM practitioner during the same visit. It is also possible to get a co-prescription for both conventional drugs and herbal medicines. It is especially important in such cases for patients to understand and strictly follow the instructions of the medical professionals. These patients need to take the remedies in the correct order, dosage, and time to minimize the risk of adverse effects.
