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.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
This supplement has been used in connection with the following health conditions:
Traditional Use (May Not Be Supported by Scientific Studies)
Traditional herbal medicine has used yarrow in three broad categories.1 First, it was used to help stop minor bleeding and to treat wounds . Second, it was used to treat inflammation in a number of conditions, especially in the intestinal and female reproductive tracts. Third, it was utilized as a mild sedative. Some or all of these historical uses occurred in Europe, China, and India. The ancient Chinese fortune-telling system known as the I Ching first used dried yarrow stems, then later replaced them with coins.2
How It Works
How It Works
A number of chemicals may contribute to yarrow’s actions. The volatile oil, which is rich in sesquiterpene lactones, and alkamides has been found to have anti-inflammatory properties in test tube studies.11 , 12 Animal studies have shown this herb can reduce smooth muscle spasms, which might further explain its usefulness in gastrointestinal conditions.13 The alkaloid obtained from yarrow, known as achilletin, reportedly stops bleeding in animals.14 No human clinical studies have confirmed the traditional uses of yarrow.
How to Use It
The German Commission E monograph suggests approximately 1 teaspoon (4.5 grams) of yarrow daily or 3 teaspoons (15 ml) of the fresh pressed juice.15 A tea can be prepared by steeping 1–2 teaspoons (5–10 grams) of yarrow in 1 cup (250 ml) boiling water for ten to fifteen minutes. Three cups (750 ml) a day can be taken. A tincture, 1/2–3/4 teaspoon (3–4 ml) three times per day, can be taken. The tea, or cloths dipped in the tea, can be used topically as needed for minor skin injuries.
