Herbal therapy is a form of alternative medicine that uses plants and their extracts for therapeutic purposes. It's based on the belief that certain plants contain natural compounds that can promote health and well-being.

Herbal therapy works by utilizing the bioactive compounds found in plants, such as alkaloids, flavonoids, tannins, and essential oils. These compounds interact with the body's systems to target and treat various conditions, ranging from common colds to more serious diseases. The specific effects depend on the plant and its active compounds. Herbal remedies can function by directly influencing bodily functions, strengthening the immune system, or providing antioxidant protection, all of which contribute to overall health and well-being.
