What Are Star Ratings?

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.

Sarsaparilla was formerly a major flavoring agent in root beer.

How It Works

Botanical names:
Smilax spp.

How It Works

Sarsaparilla contains steroidal saponins, such as sarsasapogenin, which may mimic the action of some human hormones. This property remains undocumented, however. Sarsaparilla also contains phytosterols, such as beta-sitosterol, which may contribute to the anti-inflammatory effect of this herb. Reports have shown anti-inflammatory3 and liver-protecting4 effects for this herb. Similar reports on the effect of sarsaparilla on psoriasis occur in early European literature.5

How to Use It

Sarsaparilla is often taken in capsules, 2–4 grams three times per day.6 A tincture, 2–4 ml three times per day, may also be used.
