Homeopathy is a two-hundred-year-old healing method based on the Law of Similars, the principle that a substance that causes a particular array of symptoms in a healthy person can resolve those symptoms when they appear as the expression of an illness. Homeopathy uses microdoses of natural substances to catalyze each organism's unique healing ability, stimulating the achievement of balance from within.

Classical homeopathy employs only one homeopathic remedy at a time, matching it as fully as possible to the total symptom picture of the individual. Its effectiveness depends on accurate remedy selection and assessment of the remedy's action, as well as an understanding of the fundamental principles of homeopathy.

In the United States, homeopathic remedies are manufactured by specialized pharmaceutical companies under the supervision of the FDA. Most of them are classified as over-the-counter medicines and are sold through health food stores and pharmacies. They are inexpensive and readily available, making homeopathic care practical and cost-effective.
