Wheatgrass is available planted in trays of soil and in tablets, capsules, liquid extracts, tinctures, and juices. Some people buy seeds or kits and grow it at home, either indoors or outside. It is most often made into juice  but can also be used to make tea. 

People generally drink the juice, although a few mix it with water and use it as an enema to "cleanse the liver". It is also mixed into smoothies and other drinks.
