Onion: Onions have antimicrobial properties that hasten wound healing and remove scabs without leaving scars. Prepare a paste by pounding one small freshly cut onion with a teaspoon of honey. Apply this directly on the scab and leave on for 10 minutes. Wash off and re-apply three to four times a day to prevent scars.

Underground bulbs that grow at the base of plants, onions (Allium cepa) are rich in healthy soluble fibers called fructans. Fructans are prebiotic (substances that enhance the growth of beneficial bacteria) fibers that can reduce inflammation, improve colon health and reduce the risk of colon cancer.[1,2,3]

Onions are also packed with antioxidants that reduce inflammation and suppress the growth of harmful microorganisms, particularly bacteria and yeasts.[4,5,6,7]

Animal studies show that onions can prevent bone deterioration and could even increase bone mass.[8,9,10] Another study showed that women over 50 years of age who regularly consumed onions had increased bone density.[11] Regular consumption of onions reduced the risk of several types of cancers such as breast, colon, prostate and stomach cancers.[12,13,14,15,16,17]

Onions For Diabetes
Diabetes is characterized by elevated blood sugar levels. Animal studies have found that onions can lower blood sugar levels.[18,19,20] Sulfur compounds including S-methylcysteine and flavonoids such as quercetin are mainly responsible for the hypoglycemic (blood sugar-reducing) activity of onions.

Raw onions could be used in the management of both type 1 and 2 diabetes.[21,22] A clinical study found that when people with diabetes consumed 100 grams of raw onions every day, it led to a significant reduction in blood sugar levels.[23]

How To Take It

  • Eat about eight slices of raw onion after every meal to help manage your blood sugar levels.
