Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Herbal blends labeled as "proprietary" are commonly formulated based on traditional or folk medicine practices rather than robust scientific validation. These blends often include herbs such as Vitex agnus-castus (chasteberry), Angelica sinensis (dong quai), Trifolium pratense (red clover), Paeonia lactiflora (white peony), and others, all of which have a long history of use in supporting female reproductive health in various traditional medicine systems (e.g., Traditional Chinese Medicine, Ayurveda, and Western herbalism). Historically, these herbs have been used to address menstrual irregularities, premenstrual syndrome (PMS), menopausal symptoms, and general reproductive wellness. However, the evidence supporting their efficacy is mixed and often limited to small clinical studies, anecdotal reports, or historical texts. While certain components like chasteberry have some human trials indicating efficacy for PMS, most proprietary blends lack rigorous, standardized clinical trials to confirm their effects on the female reproductive system. Additionally, the proprietary nature of these blends means that ingredient proportions and quality can vary, making scientific assessment more challenging. Thus, the justification for their use is primarily rooted in traditional practice, with only limited scientific support for some individual components.
