Patients, families, and practitioners each carry an explanatory model: a set of beliefs about the cause of an illness, when and how it began, how it works in the body, how severe it is, what course it will take, and what treatment it needs. These models are often tacit, partial, and inconsistent. Clinical trouble comes less from missing facts than from unacknowledged clashes between the patient's model and the healer's model.
Disease is the malfunction of biological or psychological processes as a practitioner's theory reframes it. Illness is the patient's and family's lived experience of symptoms, including how they perceive them, label them, and respond socially. Biomedicine treats disease and neglects illness. That is why a cured disease can leave an untreated illness, and a treated illness can bring healing even when the disease persists.
Every local health care system has three overlapping arenas. The popular sector covers self-care, family, and social networks, and it is where most illness is first defined and treated. The professional sector is organized, credentialed medicine. The folk sector covers non-professional specialists such as shamans and herbalists. Patients move among these sectors, and the popular sector is where they decide when and where to seek care and judge whether it worked.
Health care can be analyzed as a cultural system: a set of meanings, norms, and power relations linking beliefs about sickness, ways of seeking care, and ways of judging outcomes. On this view, biomedicine is one local cultural system among others, not a culture-free baseline. Its categories and its idea of a successful outcome are themselves products of culture.
Indigenous healers such as Taiwanese tâng-ki shamans often succeed because they give the sickness an authoritative, culturally meaningful name and reorder the patient's and family's experience of it. They usually treat chronic, self-limiting, or somatized conditions, and they judge success by how the illness is experienced rather than by biological cure. Their effectiveness is real, but it is effectiveness at healing illness, not at curing disease.
In Taiwan, many patients with depression and anxiety presented only bodily complaints such as fatigue, dizziness, and pain, and did not name distressed feelings. This fit a culture that stigmatized expressing emotion and made bodily idioms the acceptable way to ask for help. The case shows that culture shapes which symptoms a person experiences and reports, not just how they are interpreted afterward.
