History & Folklore
Deadnettle is so called because it resembles true nettle (Urtica dioica), without the stinging hairs. It was also known as archangel, a plant “to make the heart merry, to make a good color in the face, and to refresh the vital spirits” (John Gerard, The Herball, 1597).
Medicinal Actions & Uses
White deadnettle is astringent and demulcent. It is chiefly used as a uterine tonic, to arrest intermenstrual bleeding, and to reduce excessive menstrual flow. It is also a traditional treatment for abnormal vaginal discharge. The herb is sometimes taken to relieve painful periods. Its astringency helps treat diarrhea, and, used externally, it can relieve hemorrhoids and varicose veins.
