The numerous existing subspecies, varieties and forms are native to all temperate climates of Asia and Europe. Viola arvensis, also known as a cereal weed, is considered to be the main supplier of the drug material. This is also taken up as a subspecies of the classic field pansy and is widespread throughout the world.
Pansies in herbal medicine.
The drug material comes from wild occurrences and partly from cultures in France and Holland. In herbal medicine, the above-ground dried parts of the pansy collected at flowering time, together with the flowers (Violae tricoloris herba) are used.
