Onion is an annual to bi- annual shrub cultivated in the plains of India as a source of vegetable. The shrub grows up to 1 meter in height with the stem of the plant being green in color and white colored flower at the top. Both the stem and the bulb, which is found underground, are edible. The onion plant has been grown and selectively bred in cultivation for at least 7,000 years. Doctors were known to prescribe onions to facilitate bowel movements and erections, and to relieve headaches, coughs, snakebite, and hair loss. As a food item, they are usually served cooked, as a vegetable or part of a prepared culinary dish, but can also be eaten raw or used to make pickles or chutneys. They are pungent when chopped and contain certain chemical substances like sulphur which irritate the eyes.
Research articles about Allium cepa:
Anti- bacterial activity: Research was carried out on antibacterial activity of Allium cepa. Two different extracts were made from Allium cepa (onion) using distilled water. The extracts include fresh onion extract and cold water extract. The antibacterial activity of the onion was tested on four bacteria isolates associated with various ocular infections. The bacterial isolates include: Escherichia coli, Staphylococcus aureus, Streptococcus pyogenes, and Streptococcus pneumonia. Among the two extracts, fresh onion extracts exhibited antagonistic effects on the test organisms ranging from observed zone of inhibition (average value) of 15mm for Escherichia coli, 17mm for Staphylococcus aureus, 20mm for Streptococcus pyogenes, and 8mm for Streptococcus pneumonia.
Anti- diabetic action: The hypoglycemica and hypolipidemic activity of Allium cepa aqueous extracts was studied on Rattus novergicus (rats). The extract produced a dose dependent significant result in blood glucose level at the end of six weeks.
Enhancing immune function: Researchers evaluated and compared the effect(s) of single and combined oral administration of fresh aqueous onion (Allium cepa) and garlic (Allium sativum) extracts at different concentrations on some immunological determinants in rats. CD4 cells of the rats were estimated using Partec flow cytometric technique, while total and differential white blood cell (WBC) counts were estimated using the Sysmsex® automated haematology analyzing technique. Our findings revealed that, CD4 and total WBC counts were significantly increased (P?0.05) in a dose-dependent manner in both onion (250mg/Kg/d: 349±11cell/ul and 2.75±0.15X103cell/l; 500mg/Kg/d: 389±10cells/µl and 3.05±0.05 X103cell/l; 750mg/Kg/d: 600±11cell/µl and 3.25±0.05X103cells/l) and garlic (250mg/Kg/d: 410±10cell/ul and 2.85±0.15X103cell/l; 500mg/Kg/d: 494±32cells/µl and 3.30±0.10 X103cell/l; 750mg/Kg/d: 684±11cell/µl and 3.55±0.05X103cells/l) treated rats when compared to the zero control (200±11cells/µl and 1.55±0.05X103cells/l, respectively).
The antibacterial activity of fresh red and white Allium cepa (Onion) and Zingiber officinale (Ginger), garlic (Allium Sativum) juices against multidrug resistant bacteria viz: Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, Aerobacter aerogenes, Proteus vulgaricus pure cultures were investigated using agar well diffusion and agar dilution methods. All the bacteria were susceptible to the fresh garlic and white onion juice with the diameter of zones of inhibition ranging from 1.3cm-5.5cm while the test bacteria were not sensitive to the fresh ginger juice.
