Answer & Solution
Ayurveda is a holistic system of medicine that focuses on promoting a balanced and harmonious life by emphasizing the interconnectedness of the body, mind, and spirit. It provides guidelines for maintaining health, preventing illnesses, and treating various ailments using natural remedies, herbs, diet, lifestyle practices, and therapies.
