Homeopathy
Homeopathy is a system of medicine that was developed by Samuel Hahnemann in Germany in the late 18th century. It is based on the principle of "like cures like." Homeopathic practitioners believe that diseases can be cured by substances that produce similar symptoms in healthy people. Homeopathic remedies are made from a variety of natural substances, such as plants, minerals, and metals
They are diluted to very low levels, and homeopaths believe that this process makes them more effective.
