Benefits of Garlic

Garlic is a stool plant with long, flat grass-like leaves whose fruit is underground. The fruit is flower shaped with several simultaneously lying cloves. Each clove is covered with a paper-like thin skin and its green white or pink flowers can be seen clustered together at the end of the long branches. The branch comes directly from the flower bulb, which is used as food and medicine. The bulb is made up of many small bulbs that are covered with paper skin.

The most active ingredients of fresh garlic are ‘Alene’ (amino acid) and alinase (enzyme). When a clove of garlic is crushed, the Alene and allinase compounds are mixed to form a lysin, which is responsible for the strong smell of the garlic. Instead, the elysian splits into other sulfur compounds within a few hours. These elements have some overlapping healing properties. 


Garlic can be grown at an altitude of 1200-2000 meters above the average sea level. Garlic needs less days, cooler (12-18 °C) humid times during growth. 6-7 PH. A well-drained dry soil rich in organic matter is good for garlic. Too much acidity/acidic heavy soil is not suitable for this crop. The soil is finely planted by making a 30cm gap or convenient size bed. The cloves are planted at an interval of 15-10 cm.
