In a preliminary study, individuals with lymphedema of the arm or head-and-neck region were treated with approximately 230 mcg of selenium per day, in the form of sodium selenite, for four to six weeks. A quality-of-life assessment showed an improvement of 59%, and the circumference of the edematous arm was reduced in 10 of 12 cases.¹

Because coumarin, hydroxyethylrutosides, and diosmin are not widely available in the United States, other flavonoids, such as quercetin, rutin, or anthocyanosides (from bilberry), have been substituted by doctors in an attempt to obtain similar benefits. The effect of these other flavonoids against edema has not been well studied. Also, optimal amounts are not known. However, in one study, quercetin in amounts of 30-50 mg per day corrected abnormal capillary permeability (leakiness),² an effect that might improve edema. A similar effect has been reported with rutin at 20 mg three times per day.³ Doctors often recommend 80 to 160 mg of a standardized extract of bilberry, three times per day.

 

Cleavers is one of numerous plants considered in ancient times to act as a diuretic.⁴ It was therefore used to relieve edema and to promote urine formation during bladder infections.

 

Herbs that stimulate the kidneys were traditionally used to reduce edema. Herbal diuretics do not work the same way that drugs do, thus it is unclear whether such herbs would be effective for this purpose. Goldenrod (Solidago cnadensis) is considered one of the strongest herbal diuretics.⁵ Animal studies show, at very high amounts (2 grams per 2.2 pounds of body weight), that dandelion leaves possess diuretic effects that may be comparable to the prescription diuretic furosemide (Lasix®).⁶ Human clinical trials have not been completed to confirm these results. Corn silk (Zea mays) has also long been used as a diuretic, though a human study did not find that it increased urine output.⁷ Thus, diuretic herbs are not yet well supported for use in reducing edema.

Aescin, isolated from horse chestnut seed, has been shown to effectively reduce post-surgical edema in preliminary trials.^14,15 A form of aescin that is injected into the bloodstream is often used but only under the supervision of a qualified healthcare professional.

 

Horsetail has a diuretic (urine flow increasing) action that accounts for its traditional use in reducing mild edema. Although there is no clinical research that yet supports its use for people with edema, the German government has approved horsetail for this use. The volatile oils in juniper cause an increase in urine volume and in this way can theoretically lessen edema;¹⁶ however, there is no clinical research that yet supports its use for people with edema.
