 Biennial herb, up to 120cm tall, native probably to West Asia, only known in cultivation (nearly everywhere); various in habit, large in bloom; leaves hollow, tubular, radical and basal, swollen; stem swollen below middle; flowers white, many, in large umbel subtended by 2 or 3 reflexed bracts; bulbs often large. \\ Biennial herb, up to 120cm tall, native probably to West Asia, only known in cultivation (nearly everywhere); various in habit, large in bloom; leaves hollow, tubular, radical and basal, swollen; stem swollen below middle; flowers white, many, in large umbel subtended by 2 or 3 reflexed bracts; bulbs often large. \\
-"The onion of commerce, Allium cepa is widely cultivated as a biennial in North America, Europe, and Asia. It is unknown in the wild and is probably derived from A. oschanini of central Asia. The cultivated form is often polyploid (2n = 16, 32, 54) and possibly of hybrid origin. It exists in numerous cultivars, a few of which form large bulbils in the umbel." \\ +"The onion of commerce, Allium cepa is widely cultivated as a biennial in North America, Europe, and Asia.

 Mammals are unable to metabolize fructans, but the human colon has been estimated to harbor between 500 and 1,000 species, representing over 7,000 strains, several of them containing fructanases and can convert fructans to fructose. Products of fructan degradation include lactate, butyrate, CO2 and H2, leading to flatulence. \\ Mammals are unable to metabolize fructans, but the human colon has been estimated to harbor between 500 and 1,000 species, representing over 7,000 strains, several of them containing fructanases and can convert fructans to fructose.

 "Dipropyl disulfide and allyl propyldisulfide have been implicated in onion-induced hemolytic anemia. However, recently, more active oxidizing sulfur-containing compounds have been discovered and proposed as causative agents, either in onion or garlic poisoning episodes. Sodium n-propylthiosulfate, isolated from boiled onions, was proven to cause an increase of Heinz body formation in erythrocytes and subsequent hemolytic anemia in dogs." \\ "Dipropyl disulfide and allyl propyldisulfide have been implicated in onion-induced hemolytic anemia.

 "Hot plate and formalin tests were used to study the analgesic effect of fresh onion juice in mice during acute and chronic pain stages modeling, respectively. The anti-inflammatory effect of fresh onion juice was assessed by applying carrageenan sub plantar injection to Sprague-Dawley rats. The obtained results illustrated a significant analgesic property for fresh onion juice in both pain phases compared with positive control group (Pv≤0.05); the effects were similar to that of morphine (5 mg/kg) as the standard treatment. In inflammation assessment, fresh onion juice was able to decrease the hind paw thickness significantly in comparison with control group (Pv≤0.001). In the mean time, it also demonstrated better results than the standard treatment, diclofenac with a 10 mg/kg dosage, (Pv≤0.05). It can be concluded that fresh juice of onion is capable of inhibiting both acute and chronic pain as well as inflammation, with a more strong effect towards inflammation." \\ "Hot plate and formalin tests were used to study the analgesic effect of fresh onion juice in mice during acute and chronic pain stages modeling, respectively.
