A "Proprietary Blend (Herb/Botanical)" is a general term used in dietary supplements to indicate a mixture of various herbal or botanical ingredients. The specific contents of such blends are often not disclosed, making it difficult to evaluate their effects individually. Historically, various herbs and botanicals have been used in traditional medicine systems (such as Traditional Chinese Medicine and Ayurveda) to support female reproductive health and ovarian function. Common herbs found in these blends may include chasteberry (Vitex agnus-castus), dong quai (Angelica sinensis), black cohosh (Actaea racemosa), and others. The traditional use of these herbs often centers around managing menstrual cycles, alleviating symptoms of menopause, or supporting fertility. However, rigorous scientific validation for the efficacy of multi-herb proprietary blends is generally lacking. Some individual herbs have limited clinical evidence supporting specific uses (e.g., chasteberry for premenstrual symptoms), but the effects of the blends as a whole are largely unstudied. In summary, the use of proprietary herbal blends to support ovarian health is primarily justified by traditional usage rather than robust scientific evidence, and the evidence rating is modest due to a lack of well-controlled studies on the blends themselves.
