Can you buy cabbage juice?

Cabbage juice is best made fresh, using a juicer, so it's going to be harder to find pre-made. It is possible to buy cabbage juice powder online and you might find a local store willing to juice cabbage for you but it’s not generally a product found in the standard juice section; however, do ask your local health food store, as some might sell cabbage juice or be prepared to make it on-the-spot. If you don’t own (or don’t want to own) a juicer, ask a neighbor or friend if you could borrow theirs, or ask a local store that juices fruit and vegetables if they’d juice some cabbage for you.
