Homeopathy, a system of alternative medicine, was founded in the late 18th century by German physician Samuel Hahnemann. Dissatisfied with the harsh practices of conventional medicine at the time, Hahnemann sought a gentler approach. He discovered the principle of “like cures like” (Sciatica , Migraine , Allergic Rhinitis–Cold ) while translating a medical text and observing that a substance causing symptoms in a healthy person could be used to treat similar symptoms in a sick person.
In 1796, Hahnemann published his findings, marking the birth of homeopathy. He developed the process of potentization, which involves serial dilution and vigorous shaking (succussion) of a substance, believing this process enhanced its healing properties while minimizing toxicity. Homeopathy gained popularity in Europe during the 19th century, especially among those seeking less invasive treatments.

By the mid-19th century, homeopathy had spread to the United States, where it flourished and led to the establishment of homeopathic medical schools and hospitals. However, with the rise of conventional medicine and scientific skepticism, homeopathy’s influence waned in the 20th century.

Despite this, homeopathy remains a popular complementary medicine worldwide, especially in countries like India, Brazil, and the UK, where it continues to attract both proponents and critics.
