Some supporters believe that homeopathic remedies can cure any and every illness.
Responsible practitioners do not use homeopathic remedies to treat diabetes, cancer, heart disease, or other major illnesses. Homeopathic remedies should also not be used to treat surgical emergencies, serious infections, or bad injuries. Homeopathy is based on the idea that large doses of a substance cause a symptom, while very small doses of that same substance will cure it. Samuel Hahnemann, an 18th century German doctor, developed homeopathy. Specifically, a medicinal substance can cure the same problems that it causes.
