A "Proprietary Blend (Herb/Botanical)" is a term often used on supplement labels to refer to a mixture of various herbal or botanical ingredients whose individual amounts are not disclosed. In the context of supporting the prostate, many proprietary blends contain herbs such as saw palmetto, pygeum, stinging nettle root, and others. The use of these herbal combinations is primarily justified by traditional medicine practices, particularly in Western herbalism and some traditional African and Asian medicine systems. For instance, saw palmetto berries have been used by Native Americans for urinary and reproductive health for centuries, and pygeum has a history of use in African traditional medicine for urinary problems. However, scientific evidence for the effectiveness of these blends as a whole is limited. While some individual herbs like saw palmetto and pygeum have modest evidence from clinical trials suggesting potential benefits for symptoms of benign prostatic hyperplasia (BPH), the quality and consistency of these results are variable. Most proprietary blends have not themselves been rigorously tested in controlled studies, and the lack of transparency about ingredient quantities further complicates evaluation. Therefore, while traditional use supports the inclusion of such blends for prostate health, scientific validation is limited to the evidence for specific, individual herbs rather than the blend as a whole.
