Homoeopathy is like cures like or the law of similar as observed by German physician Samuel Hahnemann in the 19th century. We use a minute dose of the substance causing an illness to cure the same illness. It's is now clear how homoeopathy works. The remedies, including herbs, plants, minerals or other substances, stimulate a person's immune and defense systems and help the body heal itself. Remedies are usually prescribed one at a time and may change as symptoms clear. Homoeopathy is used to treat short-term illnesses such as those common to infants and children, as well as chronic ailments such as arthritis and asthma.
