General Information

Scientific Name(s): Allium cepa L.
Common Name(s): Bulbus Allii Cepae, Common onion, Contractubex, Garden onion, Mederma, Onion

Plant Description

The onion plant is a perennial herb growing to about 1.2 m in height, with 4 to 6 hollow, cylindrical leaves. On top of the long stalks, greenish-white flowers in the form of solitary umbels grow to 2.5 cm wide. The seeds of the plant are black and angular. The underground bulb, which is used medicinally and consumed as food, is comprised of fleshy leaf sheaths forming a thin-skinned capsule and varies greatly in size (2 to 20 cm). The shape (flattened, spherical, or pear shaped) and color of the bulb depends on the variety.

Constituents of Red onion

Onions contain quercetin, a flavonoid (one category of antioxidant compounds). Antioxidants are compounds that help delay or slow the oxidative damage to cells and tissue of the body.

Health Benefits of Red onion extract

Antioxidant and Anti-Inflammatory Benefits of Onions

Onions contain quercetin, a flavonoid (one category of antioxidant compounds). Antioxidants are compounds that help delay or slow the oxidative damage to cells and tissue of the body. Studies have indicated that Red oion quercetin helps to eliminate free radicals in the body, to inhibit low-density lipoprotein oxidation (an important reaction in the atherosclerosis and coronary heart disease), to protect and regenerate vitamin E (a powerful antioxidant) and to inactivate the harmful effects of chelate metal ions.

Major dietary sources of quercetin include tea, onions and apples. Recent studies at Wageningen Agricultural University, the Netherlands, showed that the absorption of quercetin from onions is twice that from tea and more than three times that from apples. Based on studies conducted at The Queen's University at Belfast, Ireland and Wageningen Agricultural University, the content of quercetin in onions is estimated to be between 22.40 mg and 51.82 mg per medium-sized onion (100 gram). Further research at the Agricultural University on Wageningen showed that daily consumption of onions may result in increased accumulation of quercetin in the blood. Studies are in progress to determine whether the increased quercetin accumulation from eating onions translates into significant antioxidant benefit.

Help Control Blood Sugar

Eating onions may help control blood sugar, which is especially significant for people with diabetes or prediabetes.

A study in 42 people with type 2 diabetes demonstrated that eating 3.5 ounces (100 grams) of fresh red onion reduced fasting blood sugar levels by about 40 mg/dl after four hours.

Additionally, multiple animal studies have shown that onion consumption may benefit blood sugar control.

A study showed that diabetic rats fed food containing 5% onion extract for 28 days experienced decreased fasting blood sugar and had substantially lower body fat than the control group.

Specific compounds found in onions, such as quercetin and sulfur compounds, possess antidiabetic effects.

For example, quercetin has been shown to interact with cells in the small intestine, pancreas, skeletal muscle, fat tissue and liver to control whole-body blood sugar regulatio.

Cancer-Fighting Benefits

Eating vegetables of the Allium genus like garlic and onions has been linked to a lower risk of certain cancers, including stomach and colorectal.

A review of 26 studies showed that people who consumed the highest amount of allium vegetables were 22% less likely to be diagnosed with stomach cancer than those who consumed the least amount.

Moreover, a review of 16 studies in 13,333 people demonstrated that participants with the highest onion intake had a 15% reduced risk of colorectal cancer compared to those with the lowest intake.

These cancer-fighting properties have been linked to the sulfur compounds and flavonoid antioxidants found in allium vegetables.

For example, onions provide onionin A, a sulfur-containing compound that has been shown to decrease tumor development and slow the spread of ovarian and lung cancer in test-tube studies.

Onions also contain fisetin and quercetin, flavonoid antioxidants that may inhibit tumor growth.

Antibacterial Properties

Onions can fight potentially dangerous bacteria, such as Escherichia coli (E. coli), Pseudomonas aeruginosa, Staphylococcus aureus (S. aureus) and Bacillus cereus.

Furthermore, onion extract has been shown to inhibit the growth of Vibrio cholerae, a bacteria that is a major public health concern in the developing world.

Quercetin extracted from onions seems to be a particularly powerful way to fight bacteria.

A test-tube study demonstrated that quercetin extracted from  onion skin successfully inhibited the growth of Helicobacter pylori (H. pylori) and Methicillin-resistant Staphylococcus aureus (MRSA).

H. pylori is a bacteria associated with stomach ulcers and certain digestive cancers, while MRSA is an antibiotic-resistant bacteria that causes infections in different parts of the body.

Another test-tube study found that quercetin damaged the cell walls and membranes of E. coli and S. aureus.

Precautions:

Onion extract is considered generally safe, with no known side effects.

Dosage

Onion-based quercetin 100 to 500 mg per day has been used in limited clinical studies.
