Garlic (Allium sativum) is a powerful medicinal and culinary herb that has been used for centuries to enhance flavor and improve health. Whether consumed raw as garlic cloves or in powdered form, garlic offers a range of scientifically supported health benefits.
What Are Cloves of Garlic?
A clove of garlic is one segment of the whole garlic bulb. A typical bulb contains 10–12 cloves. These cloves are rich in sulfur compounds, most notably allicin, which is released when garlic is crushed or chopped and is responsible for many of garlic’s health properties.
What Is Garlic Powder?
Garlic powder is a dehydrated, ground form of garlic, made by drying fresh garlic cloves and grinding them into a fine powder. It’s a convenient alternative to fresh garlic with a longer shelf life, used widely in cooking.
🔎 Note: Garlic powder contains fewer active compounds like allicin compared to fresh garlic but still offers many nutritional benefits.
