It's hard to say what the original intention of the fitness instructor is, not to learn Chinese medicine, but Chinese medicine is really harmful. The ancients had a shallow understanding of human body structure, physiology and pathology (pathogenesis), and thought that those flowers and plants had medicinal properties and could be cured when they encountered self-healing diseases. Traditional Chinese medicine is metaphysics, not science, and only scientific medicine can cure diseases. Unscientific western medicine, Arabic medicine, Egyptian medicine and Indian medicine have all been eliminated by their respective countries and regions, although traditional medicine in these countries is much earlier than traditional Chinese medicine and has made much greater achievements.
