Adenoids are masses of lymphatic tissue located in the nasal cavity that help fight infections. They are largest in childhood but typically shrink by adulthood. Homeopathy can effectively treat enlarged adenoids. Key homeopathic remedies include Baryta Carb, Agraphis, and Calcarea Carb, which are prescribed based on symptoms like frequent colds, susceptibility to infections, and emaciation. Homeopathy aims to strengthen the immune system to naturally reduce adenoid size during infections.
