Chinese medicine unlike Western medicine doesn’t really have any side effects. The effects you’re feeling are mostly from the elimination of toxins from the body, especially from all the drugs you’ve taken over the years. Think of a person who has taken illegal drugs for many years. Then think of how the person feels when they’re in withdrawal. It’s almost the same analogy. You may experience some vomiting, diarrhea, or other forms of “discomfort” after taking herbal medicines but that is merely the medicine eliminating toxins from the body.
