Around 400 BC, Hippocrates is supposed to introduce the Homeopathic principle — “similar cures similar”—when he recommended mandrake root (that produced mania) in order to heal mania ailment. He recommended a dose smaller than the amount that would induce mania ailment. Then after, Paracelsus—the pioneer of pharmacology in the 16th century—heralded small doses of “what makes a man ill also cures him."
Nonetheless it was German physician Samuel Hahnemann who originated the science of Homeopathy—healing based on the "law of similars"—in 1796. He denied the idea of an ailment as a separate thing or offensive factor. Rather he believed the ailment as a part of the "living whole." It was Hahnemann who proposed Homeopathy totally against the healing pattern of traditional western medicine, and even coined the term “Allopathic medicine” pejoratively. Therefore, Homeopathy never recommends any patient to go through the treatments like vaccinations, anti-malarial drugs, and antibiotics that are supposed to suppress the symptoms of the ailments.
