Where does the onion grow?

The onion grows in Europe and America, and also in Brazil. The onion can reach a height of between 60 and 120 cm. Flowering, which takes the form of a spherical inflorescence, occurs in Europe between June and August (summer). It is a perennial plant, that is, it can live for several years. Some sources speak of a biennial plant.


– The onion is a plant widely used in cooking, and due to its high content of sulfur derivatives it causes tears in the cook. In phytotherapy, it is not so used, but it is present in home remedies against insect bites or allergies. However, in case of high cholesterol, garlic is more used (also rich in alliin). Furthermore, this plant is widely used in homeopathy, under its Latin name Allium cepa . It is mainly used in case of allergy, sinusitis or allergic rhinitis.

– There are more than 1000 varieties of onion ( Allium cepa ).
