Homeopathy is the practice of treating like with like. As with other complementary therapies, it looks at the person as a whole rather than treating back pain in isolation. Remedies are derived from mineral, plant and animal sources and are administered in small doses. Some chemists stock homeopathic remedies, but it's better to get a skilled practitioner to assess your condition first rather than trying to prescribe for yourself. Registered homeopaths must be qualified already in ordinary medicine before they can take a diploma in homeopathy.
