Other names: self-heal, heal-all
Prunella Vulgaris is an herbaceous plant from the mint family with a long history of time-honored use. The leaves have been used externally as an antiseptic and to promote healing. Taken internally, it has been used in many cultures as a medicinal tea.
These benefits may be directly associated with the herb’s nutrient content, which includes vitamins A and C, rutin, flavonoids, antioxidants, alkaloids, phenols, tannins, proteins, lipids and glycoside.
One of the most prominent antioxidants found in Prunella Vulgaris is rosmarinic acid. Studies have attributed the plants potential to support the skin’s response toUVA radiation to this particular nutrient. Additionally, research shows that Prunella Vulgaris may help to promoted defenses against UVA induced changes that cause DNA damage, and may also work as a photo-protective agent.
In one study, researchers noted that “P. vulgaris and RA, used in skin care cosmetics, may offer protection against UVA-induced oxidative stress and may be beneficial as a supplement in photoprotective dermatological preparations.”
