The purple onion is a biennial plant that belongs to the Liliaceae family and has its origin in Southwest Asia.

It is important to mention the difference between white onion and red onion. The latter is richer in antioxidants, which is where its purple color comes from. It also contains a higher amount of quercetin, a potent antioxidant with anti-inflammatory and anti-allergic effects, which also favors blood circulation.

Among the benefits of red onion are the following:

• It prevents the formation of clots and improves blood circulation.
• Combats circulatory diseases.
• It also regulates cholesterol levels.
• It helps to improve other circulatory problems such as hemorrhoid formation.
