Consider the choices ... Conventional medicine: The beginning of conventional medicine can be traced back to the fifth century B.C. in ancient Greece. It is based on the scientific study of the human body and illness. In the last century, there has been great progress in what doctors have been able to do with modern surgery and new medications. These scientific advances have made conventional medicine the method many people choose first when they need medical treatment. Homeopathy: Homeopathy was founded in the late eighteenth century in Germany. It is a low-cost system of natural medicine used by hundreds of millions of people worldwide. In homeopathy, a patient’s symptoms are treated with remedies that cause similar symptoms. Herbal therapy: Herbal medicine, often taken as teas or pills, has been practised for thousands of years in almost all cultures around the world. In fact, many conventional medicines were discovered by scientists studying traditional uses of herbs for medical purposes. The World Health Organization claims that 80% of the world’s population uses some forms of herbal therapy for their regular health care. Acupuncture: Acupuncture originated in China over 5,000 years ago. Today, it is used worldwide for a variety of problems. Acupuncture needles are inserted at certain points on the body to relieve pain and/or restore health. Many believe acupuncture may be effective in helping people stop smoking as well. Spiritual healing: Also known as faith healing, or “mind and body connection”, various forms of spiritual healing exist around the world. This is a form of healing that uses the mind or religious faith to treat illness.
