Phytotherapy is a form of medical treatment which relies on the use of plants, either whole or in the form of prepared extracts and essences. For thousands of years, plants were a primary source of therapeutic medication for cultures all over the world. With the 20th century came the development of synthesization techniques and totally synthetic drugs, causing phytotherapy to fall out of popularity. However, plants still have a very important place in medicine, and they will continue to do so well into the foreseeable future.
This technique involves the study of plants to determine their properties, and the careful application of plants to treat medical problems. Herbal medicine is a form of phytotherapy, and many of the remedies used in homeopathy are also phytotherapeutic in origin. Extracts of plants are also used in the preparation of some commercial pharmaceuticals, as are synthetic drugs which are based on compounds found in plants. Researchers are also constantly studying plants to find new pharmaceutical compounds and potential applications for them.
When phytotherapy is conducted responsibly, the preparations used are standardized, which means that they are grown, harvested, and processed in a way which is designed to create a very reliable and stable dose of active ingredients. Many processors regularly test batches of the medicines they prepare to confirm that the active ingredients are present and exists in the concentration expected, and producers of such drugs also breed, grow, and harvest plants in ways which are designed to enhance reliable performance.
