Therefore, it is wrong to prohibit drugs other than Chinese herbal medicines from being added to the diet. Traditionally, the list of substances that are both food and Chinese herbal medicines is formulated and published by the health administrative department of the State Council in conjunction with the food and drug supervision and administration department of the State Council.
