It is not recommended to drink coffee while taking Chinese medicine, because coffee is a tropical crop with a bitter taste. In terms of medicinal properties, it contains some fatty substances and has a stimulating effect, so it is usually considered to be warm in nature. If this substance is taken at the same time with Chinese medicine, there is a great possibility that some of the components of the drug will conflict with it, affecting the efficacy, especially when taking some sedative and tranquilizing drugs, coffee will have a significant effect on the role of these drugs to reduce the effect of clinical treatment. For some other drugs such as pungent and warm dispersing drugs, coffee may enhance the efficacy of these drugs, resulting in too much dispersal, which is also detrimental to the health of the patient. Therefore, coffee is only used as a daily drink to wake up the mind and brain, and patients should avoid drinking coffee at the same time while taking Chinese medicine.
