Indigenous to the Northern Hemisphere, with at present about 500-700 species. In Malesia some taxa are cultivated, all are introduced, either from China, Central Asia, or Europe. They are all well-known Allium crops, grown worldwide.


Of Allium plants the bulbs, cloves, pseudo-stems, leaves, and young inflorescences are used as vegetable and condiment. Allium species are also widely used in different medicines for treating various diseases, e.g., diarrhoea, eye-infections, and headaches. Nowadays lowering of the blood pressure and inhibition of blood plate aggregation are considered the most important medical effects of Allium consumption. Many Allium species are grown as ornamentals; however, not so in Malesia because Allium species usually do not flower under tropical conditions.
