Parts Used & Where Grown

The horse chestnut tree is native to Asia and northern Greece, but it is now cultivated in many areas of Europe and North America. The tree produces fruits that are made up of a spiny capsule containing one to three large seeds, known as horse chestnuts. Traditionally, many of the aerial parts of the horse chestnut tree, including the seeds, leaves, and bark, were used in medicinal preparations. Modern extracts of horse chestnut are usually made from the seeds, which are high in the active constituent aescin (also known as escin).

  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
