Can onion water cure constipation?

Onion water may generally help alleviate constipation as a supplementary remedy.

Constipation usually occurs when stool moves too slowly through the intestines, preventing effective elimination from the rectum. This leads to stool dehydration, hardening, and dryness. Onion water typically contains a certain amount of sulfur, which, once ingested, may bind with proteins or intestinal bacteria to produce hydrogen sulfide. This process can stimulate gastrointestinal motility, helping maintain bowel regularity and providing some supportive relief for constipation, although it cannot completely cure the condition.

When experiencing constipation, it's important to adjust dietary habits, establish proper bowel movement routines, and ensure adequate food and fluid intake, which generally helps improve symptoms.
