  • Anti-Bacterial and Anti-Microbial Ingredients — Sulphides and thiosulfinates help to prevent illnesses such as E. coli, bacillus subtilis and salmonella.

  • Lower Blood Sugar, Helps with Diabetes — Onions contain a compound called allyl propyl disulphide (APDS), which harnesses blood sugar-lowering effects. One study found that “The administration of allyl propyl disulphide (APDS), a volatile substance contained in onion…caused a significant fall in the blood glucose levels and a significant rise in the serum insulin levels…” Onions are also high in chromium, a mineral which helps cells respond to glucose.

Cutting the onion allows the juice to diffuse. Helping to ease pain and dizziness, onions make up one option for home remedies for earaches.
