Scallion (Allium fistulosum L.) also known as Welsh onion or Spring onion or shallot or green onion, is a perennial plant originated in China and is cultivated in Europe and South Asia. It belongs to the family of Liliaceae.

It has traditionally been used to treat headaches, abdominal pains, common colds, cardiovascular diseases.

An extract of Allium fistulosum and Viola mandshurica led to a reduction in body weight, fat mass, adipocyte size by improving serum triglycerides, total cholesterol and leptin levels in obese rats (1).

Scallion has demonstrated antioxidant and antihypertensive activity in a 6-month study of obese rats fed with a high-fat high-sucrose diet (2).

The bulb of Allium fistulosum contains essential oils consisting of allicin, raw fat, raw protein, raw fiber, N-free extract, pentosan and polysaccharides (3).
