For the health condition: PMS Type H
Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Blackhaw (Viburnum prunifolium) has a long history of use in traditional herbal medicine, particularly among Native American and early American herbalists, for various gynecological issues, including menstrual cramps, uterine spasms, and symptoms associated with premenstrual syndrome (PMS). PMS Type H is characterized by symptoms such as bloating and water retention (the "H" stands for hyperhydration). Blackhaw is believed to exert antispasmodic effects on uterine muscle and has been used to alleviate cramping and discomfort related to the menstrual cycle. While some herbal texts and traditional sources cite its use for "fluid retention" or "edematous" conditions, the direct evidence for its effect on PMS Type H symptoms is based more on anecdotal reports and historical usage rather than robust scientific studies.
Modern scientific research on Blackhaw is limited, and there are few, if any, high-quality clinical trials evaluating its efficacy specifically for PMS or its subtypes. The rating of "2" reflects the fact that while there is a strong traditional basis for its use in menstrual-related symptoms, scientific validation for its effectiveness in PMS Type H (bloating/water retention) is weak or absent. Most available evidence remains preclinical or derived from broader applications in gynecological health, rather than rigorously controlled studies in humans focused on PMS Type H.
