Penn Herb Wellness Guide
Edema
- 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 some in 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.

Bilberry | Refer to label instructions |  [1 star] Because coumarin, hydroxyethylrutosides, and diosmin are not widely available in, flavonoids such as anthocyanosides (from bilberry), have been substituted by doctors. The effects of these flavonoids against edema has not been well studied. |

Dandelion | Refer to label instructions | [1 star] Dandelion leaves have diuretic effects that may be comparable to the prescription diuretics used to treat edema. |
Goldenrod | Refer to label instructions | [1 star] Herbs that stimulate the kidneys (diuretics) theoretically should help reduce edema. Goldenrod is considered one of the strongest herbal diuretics. |
Horse Chestnut | Refer to label instructions | [1 star] An ingredient in horse chestnut seed has been shown to effectively reduce post-surgical edema in preliminary trials. |
Horsetail | Refer to label instructions | [1 star] Horsetail has a diuretic action that accounts for its traditional use in reducing mild edema. |
Juniper | Refer to label instructions | [1 star] The volatile oils in juniper cause an increase in urine volume and in this way can theoretically lessen edema. |
Quercetin | Refer to label instructions | [1 star] In one study, the flavonoid quercetin corrected abnormal capillary permeability (leakiness), an effect that might improve edema. |
