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.
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.
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.
