A good question. There are many illnesses which are too advanced or simply too difficult to help. Homeopathy has not been shown to have helped many neurological problems such as Parkinson’s, Alzeheimer’s, and Amyotrophic Lateral Sclerosis.
Insulin dependent diabetes is a difficult illness to treat. Most diabetics have not been able to get off insulin with homeopathy though the diabetic’s general health can be helped greatly. Non-insulin dependent diabetes, on the other hand, can be helped by homeopathic treatment in conjunction with a low carbohydrate diet.
Heart conditions should be seen by a cardiologist and by your homeopath. Arrhythmias (abnormal heart rhythms) have been cured with homeopathy as well as other conditions.
Cancer is a vast, multifaceted disease which is extremely difficult to treat. Owing to the current legal climate in the USA most homeopaths do not wish to treat cancer. If a person with cancer wishes to try homeopathy in addition to whatever else he might be doing, he might be helped. As a sidebar, I have seen homeopathy help diminish the side effects from chemotherapy quite dramatically.
Fractures should, of course, be set and cast by an orthopedic surgeon. But call your homeopath immediately as he can give you remedies to reduce the swelling and speed union of the fracture.
Manipulation of the musculo-skeletal system is best taken care of by an osteopath, chiropractor, rolfer or massage therapist.
Throughout this Web site, I have been saying that the correct homeopathic medicine can help this or that condition. Note: It must be the correct medicine, however, for with the wrong one the patient never gets better. No homeopath finds the correct medicine the first time, every time, so patience might be in order. When the correct medicine is found, the results are often dramatic.
