Herbs of course have an effect on the human body, and if they are to be treated, they have to have a positive therapeutic effect on the body. When the body does not need treatment if eaten, some people do not need to take tonic, but eat tonic will produce adverse effects, such as itself is hot and eat hot tonic, it will produce adverse effects. If the body itself is deficient, cold, eat warming tonic, it will have a positive impact. There is a saying in Chinese medicine that all medicines are biased and have certain bias and medicinal properties, so of course herbal medicines have an effect on the human body.
