Homeopaths are trained to look at a person's health history as an evolution of the expression of the vital force. Symptoms, illnesses and their treatment, along with a history of emotional traumas or griefs during an earlier period of life, are understood to have a vital impact on the current state of health.
Sometimes a symptom that was eliminated by an operation or strong medication, or a strong emotion that was never expressed, will be transformed into a deeper level of disease in the person. This phenomena is called "suppression." In our present society, suppression is a very frequent phenomenon.
The most typical cases involve skin diseases rashes, eczema, psoriasis or acne - that have been treated with topical ointments. Sometime later, a chronic allergy or respiratory problem may occur. When that is treated conventionally, the vital force expresses itself through yet another disease. And so, years later, a deep-seated chronic condition is established.
Under homeopathic care, such cases often begin to reverse themselves. An asthmatic patient will notice an old skin rash reappear as their breathing improves. Or a person with migraines relives a grief was never expressed. Although this may cause consternation in the patient, it really is a sign that the case is moving forward.
