Self Heal Benefits & Uses (Prunella vulgaris)

Self heal (Prunella vulgaris) is a low-growing perennial herb in the mint family (Lamiaceae) native across Europe, Asia, and North America. It spreads by creeping stems, produces purple flower spikes, and is most often harvested for its aerial flowering parts.

In folk herbal traditions, self heal has been used in teas, rinses, gargles, and topical preparations. The leaves and flowering tops are the parts most commonly gathered, and the herb is especially associated with simple household remedies.

Because it grows close to the ground and can spread readily, self heal is often found in lawns, edges, and lightly disturbed ground as well as herb gardens.
