Look for lemongrass in the herb section of your supermarket. Lemongrass can be sold in long stalks that you chop yourself, short stocks in a plastic container, or as a jarred or bottled paste.

When it comes to Thai cooking, the lower portion of the stalk of the lemongrass is widely used as a herb in Thai cuisine. It is typically cut or chopped to form marinades, soups, or stir-fries. It serves as an added ingredient in curries, fish, poultry, beef, and seafood dishes. It can even be used for brewing tea.

Lemongrass in Thailand is called takhrai (ตะไคร้).

Look for lemongrass that is firm and pale yellow-green with a bit of a bulb at the end. The top of the stalk should look relatively fresh; they tend to dry out quickly so they may not look like they were just harvested but they shouldn't be browned or sad looking.
