A Vogel Viola tricolor (wild pansy) is a small plant, rarely reaching beyond 6 inches in height. It can be found in the wild in many parts of Europe. It looks similar to the cultivated Pansy plants many people will be familiar with, but has smaller flowers and leaves.
A Vogel Viola tricolor also has another common name, Heartsease, with a long history of use for many different conditions. Today, we know that Viola tricolor contains a special type of molecule known as cyclotides, or circular peptides. These substances are very stable because of their structural shape.
