Benefits of Garlic

Garlic is a herb grown throughout the world. It belongs to the genus Allium and is closely related to onion, chives and leek. It is widely used for flavouring in cooking, and has medicinal properties as well.

Garlic produces chemical allicin that gives it a strong smell. It contains a large number of cloves with an average height and diameter of 2 inches. The cloves and the bulb are covered with a paper-like sheath. It has a very pungent taste and adds a nutty flavour to the food.

There are different types of garlic:

  • Softneck garlic: This is the most common type of garlic with soft skin and creamy white colour, often found in the market.
  • Silver garlic: It has a pink tint on its outer sheath and has a very pungent aroma.
  • Artichoke garlic: It has large and fewer cloves with a mild flavour.
  • Hardneck garlic: It has a hard, woody stalk with a purple outer sheath.

Garlic grows mainly under low temperatures. It grows best in temperate climates with well-drained loamy soil. They are planted in the months of August to November and harvested within 4 to 5 months and the bulbs are then dried to increase their shelf life.

The extract of aged garlic can help lower cholesterol by 10%. Research was carried out on rats and it was found that garlic inhibited the synthesis of cholesterol in the rat liver cells.

Reduces the Risk of Cardiovascular Diseases

Garlic prevents cardiovascular diseases by lowering lipids and bad cholesterol. It is largely effective against atherosclerosis.

Garlic is beneficial against osteoporosis and arthritis. Research was carried out on lab rats where they were supplemented with garlic oil. It was observed that garlic oil could suppress ovariectomy-induced bone resorption.
