Selfheals

Selfheals, also called self-heal or heal-all, refers to herbaceous plants in the genus Prunella, especially Prunella vulgaris, a member of the mint family (Lamiaceae). It is a perennial that forms low mats with square stems, opposite oval leaves, and dense spikes of purple to violet flowers that bloom from late spring to autumn.

The common name heal-all reflects traditional medicinal use. Native to Europe, Asia, and North Africa, it is now naturalized on other continents and commonly found in meadows, pastures, lawns, and waste areas. It prefers moist, well-drained soils and sun to partial shade.

In traditional medicine, self-heal has been used to treat wounds, sore throats, inflammation, and infections. Phytochemical analyses identify polyphenols such as rosmarinic acid, phenolic acids, and flavonoids. Laboratory studies report antimicrobial, anti-inflammatory, and antioxidant activities; clinical evidence supporting medical efficacy is limited, and products should not replace professional care.

Self-heal is easy to grow from seed or division and establishes quickly. It provides nectar for pollinators and can spread in favorable conditions, sometimes behaving as a ground cover or weed in lawns.

While generally considered safe in typical culinary or traditional contexts, some individuals may experience allergies or interactions with medicines. People with pregnancy or certain medical conditions should consult a healthcare provider before using self-heal as a remedy.
