Complementary therapy is a holistic approach to healthcare that involves using non-traditional or alternative treatments alongside conventional medical treatments. These therapies are often used in conjunction with mainstream medical care to address the physical, emotional, and spiritual well-being of patients. Examples of complementary therapies include acupuncture, chiropractic care, massage therapy, herbal remedies, yoga, and meditation. Research in this area typically focuses on the effectiveness and safety of these therapies, as well as how they can be integrated into conventional medical practices to improve patient outcomes.
