Of course, much of Chinese medicine indeed is superstition. However, modern medicine is also not 100% "scientific". Many modern medicine treatments are not suitable for humans, but they are still in practice nonetheless because of our blind belief in science.
I don't think superstition belongs to a specific knowledge, tradition or custom. Nor do I think it's a privilege of religion. I think it is a human attitude exhibits in all intellectual fields. I think superstition in a sense can be understood as a blind belief in our imagined super power, or "absolute", derived from our despair over human condition. So as long as human race exists, superstition will always play its rule.
