How does Homeopathy work?

Homeopathy works by stimulating the body's own healing power. It is based on the Law of Similars "like cures like". In other words, a substance which can cause symptoms to appear in a healthy person can also cure those symptoms when they appear part of a disease. For example, If you've ever peeled an onion, you know that it can make your eyes tear and your nose run; it can even make you want to clear your throat. This is because your body is reacting to the volatile oils in the onion, which affect the mucous membranes of your nose and throat. The homeopathic remedy Allium cepa is made from fresh red onions; it has the same effect on the body as an onion. Therefore, in homeopathy this remedy is often prescribed to treat colds marked by burning nasal discharge and extremely dry coughs.

All homeopathic remedies are completely safe by virtue of a step-by-step dilution process called potentisation, which takes away the toxicity but dramatically increases the healing power of the original substance.
