Prunella is a genus of herbaceous plants in the family Lamiaceae, also known as self-heals, heal-all, or allheal for their use in herbal medicine.
Habitat
Most are native to Europe, Asia, and North Africa, but Prunella vulgaris (the Common Self-heal) is Holarctic in distribution, occurring in North America as well, and is a common lawn weed. Self-heals are low-growing plants, and thrive in moist wasteland and grass, spreading rapidly to cover the ground. They are members of the mint family and have the square stem common to mints.[1][2][3]
Biological descriptions
The common name "self-heal" derives from the use of some species to treat a range of minor disorders. Self-heal can be grown from seed, or divide clumps in spring or autumn.
