A pod of garlic is just the bulb that has more than one clove in it. It is the most common part of the plant that is used to make medicine and food.
Like the bulbs of many other plants, garlic pods grow underground, and the part that grows above ground can get as high as 2 feet.
Depending on the type of garlic, most pods or bulbs have between four and twenty cloves. For example, the cloves in Thai garlic are smaller and there are more of them than in many Western varieties.
To get garlic ready to use, the cloves are taken out of the pod, peeled (if needed), and usually crushed. Garlic can be used fresh, dried, freeze-dried, made into oil, or put through different processes to get allicin and other sulfur-containing chemicals.
