Homeopathy is an alternative medicine which is based upon the use of similarity principle.
The founder of homeopathy Dr. Samuel Hahnemann formulated the principle and stated that the symptoms of an ill person can be cured with the help of a substance which produces similar symptoms in a healthy person.
It is similar to the principles of Hippocrates and Paracelsus. Hahnemann and his followers had undertaken extensive study and conducted experiments on themselves. They then painstakingly recorded the results to prove the principle of similarity.
His book the Organon is still considered the best starting point for researches in homeopathy. The fundamental rules prescribed in the book still hold true even after two centuries of being first published.
The principle claims that if a person suffering from an illness is given highly diluted extracts of a particular herb or other natural substances, that cause similar symptoms, there will be success in treating the ailment.
The pain treated with the pain is another way to put it. Through this method, homeopathy focuses on the cause of the disease and based on the symptoms fights the actual illness.
The similarity principle is considered in the modern times the most common way of preventing a disease from expanding.
The herbal properties it uses and the way this principle focuses in making the body more resilient in front of future odds of getting ill, promises a future world when diseases will be prevented from ever occurring, a healthier and happier world.
