Citrus Bioflavonoids Usage

Written by FoundHealth.

Therapeutic Uses

Double-blind trials suggest (but do not prove conclusively) that a micronized combination preparation of diosmin and hesperidin may be helpful for hemorrhoids . 1 Diosmin and hesperidin, as well as the bioflavonoid rutin, may also be helpful for chronic venous insufficiency , a condition in which the veins in the legs begin to weaken. 2 At least one good double-blind trial found diosmin and hesperidin also to be helpful for individuals who develop bruises or nosebleeds easily. 3 Citrus bioflavonoids have also been tried, with some success, for treating lymphedema (arm swelling) following breast cancer surgery . 4

Note: Do not use bioflavonoid combinations containing tangeretin if you are taking tamoxifen for breast cancer.

In addition, highly preliminary evidence suggests that citrus bioflavonoids may help reduce cholesterol levels, 5 control inflammation, 6 benefit people with diabetes , 7 and reduce allergic reactions , 8 and prevent cancer .

"Sweetie fruit," a bioflavonoid-rich hybrid of grapefruit and pummelo, has shown a bit of promise for treatment of high blood pressure . 9
