Homeopathy is a system of medicine based on the principles of “like cures like” that was founded in the 1700s by the German Physician and Chemist Samuel Hahnemann.
The principle of “like cures like” is similar to the principle of getting a vaccine, in that, a similar product to the one that can cause disease is used in minute amounts to help cure the original problem. For example, arnica is a plant that in high doses can cause muscle problems, but when used in diluted amounts of 1 in 10 times the dose , it can be very effective for muscle sprains injuries, and pain.
