World Homoeopathy Day is observed every year on April 10. The date commemorates the birth anniversary of Samuel Hahnemann, the founder of the homoeopathic system of medicine. The theme chosen for 2026 is "Homoeopathy for Sustainable Health". The day is used to spread awareness about homoeopathy and its role in healthcare. Homoeopathy is one of the systems recognised under AYUSH (Ayurveda, Yoga, Unani, Siddha and Homoeopathy) in India.
