Few pharmacies nowadays sell Chinese medicines in their original unprocessed form. Instead, a variety of pills, powders and granules are available. These are Chinese patent medicines.
What is Chinese patent medicine?
Chinese patent medicine (zhong cheng yao ) is a medicinal preparation using natural medicinal materials as the ingredients. Based on the theories of TCM, zhong cheng yao is produced through processing, with an indication of the medicinal function, adaptive symptoms, dosage and method of consumption. It is the finished TCM product for a TCM compound prescription.

What are the disadvantages of patent medicine?
The combination and dosage used in the preparation of patent medicines is fixed and cannot be adjusted to suit different illnesses.
