Also known as herbal medicine or herbalism, botanical medicine involves the use of plants to treat disease and promote health. Animals and plants have evolved alongside each other for millennia, so it makes sense that our bodies respond readily to plant medicines. Like many of the naturopathic modalities, herbal medicine is a very old form of medicine used by cultures all around the world. Botanical medicines are used in both traditional herbal formulations and as phytomedicines, which are scientifically researched and formulated. A resurgence of scientific research is demonstrating that some plant substances are superior to synthetic drugs in clinical studies.
