Homoeopathy sees disease as a disturbance of the vital force — the dynamic, life-sustaining energy that maintains balance and harmony in the body, mind, and emotions. When this vital force is disturbed by internal or external factors (such as emotional shock, infection, heredity, or lifestyle), it manifests as symptoms.

Therefore, disease is not merely a physical condition, but a total dynamic disturbance of the person’s inner energy.

“It is the morbidly affected vital force alone that produces disease.”
