Health is a quality that people sense and perceive in their own bodies. Medical conditions, such as emphysema, thrombocytopenia purpura, and moniliasis are abstractions that are proper for a physician to detect, monitor, and treat, if she can. The TCM herbalist and her client cannot and should not operate in this realm. To do so risks loss of common sense as demonstrated by the cayenne debacle. TCM herbalists are better off legally and ethically when they educate their clients in listening to their bodies' symptoms so that they can better self-regulate their own health. Claims of cures for medical illnesses that are only detectable with microscopes, CT scans, and blood tests changes the terrain to that of the unseen, which neither the herbalist nor her client is capable of perceiving directly. Medical entities should not be the focus of herb choices for improving the client's health, a quality that one does perceive.
