Homeopathy is a form of alternative medicine. It was created in the 18th century by Samuel Hahnemann. The basic theory behind Homeopathy is that a sick person can be healed using something that produces the symptoms of the illness in a healthy person. May believe that there is scientific evidence that homeopathy helps in many problems and diseases. Homeopaths make their medicines by taking the ingredients, adding water, and shaking the mixture. They then take a drop of the mixture, throw out the rest, and add more water. They do this usually 30 times but sometimes up to 200 times. They call it potentization.
