Homeopathy is a system of natural medicine founded by Dr. Samuel Hahnemann, a German physician and chemist, more than 200 years ago. The word homeopathy comes from two Greek words: homeos = similar; pathos = suffering. Homeopathy is a method of healing that uses a similar medicine to treat a similar suffering. For example, peeling an onion causes itchy, watery eyes. Homeopathic onion can be used to treat someone suffering from hay-fever. The homeopathic onion produces a similar expression to the hay-fever symptoms and the suffering is relieved. The power of a medicine lies in its ability to mimic the natural disease it is used to treat. Homeopathy has continued to evolve over the past 2 centuries, and it has spread throughout the world. It is included in the health-care systems in many countries. Homeopathy is a safe, gentle, and effective method of treatment for both acute and chronic illness. It is also cost-effective, and it does not deplete our global natural resources.
