Synopsis

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

Herbal blends labeled as "proprietary" are commonly used in traditional medicine systems to support cardiovascular health, including arterial function. The use of various herbs for this purpose is grounded primarily in historical and ethnobotanical practices rather than robust modern scientific validation. For example, herbs such as hawthorn, garlic, and ginkgo are frequently included in such blends due to their longstanding use in folk medicine for supporting circulation and heart health. Historical records from Traditional Chinese Medicine and European herbalism describe the use of these and similar botanicals to "invigorate the blood" or "strengthen the heart and vessels." While some individual herbs in these blends have limited scientific studies suggesting potential benefits for blood pressure, cholesterol, or vascular flexibility, the evidence for proprietary blends as a whole is sparse. Most clinical trials focus on isolated plant extracts rather than blends, and quality, composition, and dosing are highly variable in commercial products. Therefore, while traditional use is well-documented, and some plausible mechanisms are proposed based on constituents (such as flavonoids or sulfur compounds), there is insufficient high-quality scientific evidence to conclusively support the efficacy of general herbal blends for arterial health.
