Onion Health Benefit 

Possibly Health Benefit of onion

  • Scarring – Most research shows that applying gel containing onion extract to the skin, alone or with other ingredients, for at least 10 weeks improves the appearance of scars. Applying onion extract along with other ingredients for less time doesn’t seem to work.
  • Hair loss (alopecia areata) – Early research shows that applying onion juice to the scalp for 8 weeks might improve hair growth in people with hair loss due to a condition called alopecia areata.
  • Diabetes – Early research shows that eating 20 grams of onion while dieting reduces blood sugar in people with diabetes better than dieting alone after 8 weeks of treatment.
  • High blood pressure – Research shows that taking onion extract for 6 weeks slightly reduces systolic blood pressure (the top number) in people with high blood pressure. Early research also shows that taking a combination product containing onion and other ingredients for one week lowers systolic blood pressure in people with high blood pressure. But neither supplement seems to improve diastolic blood pressure (the bottom number).
  • Obesity – Early research shows that taking onion skin extract for 12 weeks reduces body weight by a small amount in people who are overweight or obese. But the improvement might not be clinically meaningful.
  • Polycystic ovary syndrome (PCOS) – Eating large amounts of raw red onion (80-120 grams daily) does not improve cholesterol or blood sugar levels in people with polycystic ovary syndrome compared to eating smaller amounts (20-30 grams daily). Eating large amounts might actually increase body mass index (BMI) by a small amount.
  • Prostate cancer – People who eat more onions don’t seem to have a reduced risk of prostate cancer.
  • Stretch marks – Early research shows that applying a skin cream containing onion extract, gotu kola, and hyaluronic acid for 12 weeks improves the look of stretch marks.
  • Scarring – Most research shows that applying gel containing onion extract to the skin, alone or with other ingredients, for at least 10 weeks improves the appearance of scars. Applying onion extract along with other ingredients for less time doesn’t seem to work.
