Christopher Hobbs:
“Black haw is a uterine tonic used for threatened miscarriage and is often combined with blue cohosh. It is a specific for dysmenorrhea with such symptoms as uterine cramps before and during menstruation, and it is also used after childbirth for pain and bleeding. Black haw contains scopoletin, a constituent with strong uterine sedative properties. It can be used as a tea for diarrhea due to irritable bowel conditions, because of its astringent and antispasmodic actions.
Black Haw has a taste of ASTRINGENT, BITTER and a temperature of COOL.”
Modern Clinical Uses by Herbalists & Naturopaths:
Today, black haw is often recommended by herbalists and naturopaths for its antispasmodic and uterine relaxant properties. It is commonly used to alleviate menstrual pain, relieve symptoms of menopause, and support uterine health. Black haw is also sometimes used for digestive spasms and other types of cramping.
Chemistry:
Black haw contains several bioactive compounds, including flavonoids (like quercetin and scopoletin), tannins, and a unique compound called viburnin. These contribute to its antispasmodic, anti-inflammatory, and potential analgesic effects.
Pharmacology:
The plant’s effects are primarily attributed to its flavonoids, which help relax smooth muscles and reduce uterine contractions. The viburnin and other compounds contribute to anti-inflammatory and possibly mild sedative effects, which may aid in pain management and cramp relief.
Clinical Trials Summary:
Clinical trials on black haw are limited, with most evidence coming from animal studies or anecdotal reports. Some research supports its uterine-relaxant effects, but further studies are needed to confirm its efficacy and safety in human populations for specific health conditions.
In summary, black haw shows promise for managing menstrual and muscle cramps, but clinical evidence is still developing.
