What does Phytotherapy refer to?

Phytotherapy specifically refers to the use of plant extracts and compounds for therapeutic purposes. This practice involves utilizing various parts of plants, such as leaves, roots, flowers, and seeds, which contain bioactive compounds that can have medicinal effects. In many traditional and modern medicinal systems around the world, phytotherapy is utilized as a means of treating a wide range of ailments, by leveraging the natural healing properties of plants.

While other options mention different aspects of health and agriculture, they do not align with the definition of phytotherapy. The use of animal derivatives is relevant to a different field of medicine, and the study of organic farming methods and soil health pertains to agricultural practices rather than therapeutic applications of plant-derived substances.
