arugula, (subspecies Eruca vesicaria sativa), also called roquette, salad rocket, garden rocket, or rugula, annual herb of the mustard family (Brassicaceae), grown for its pungent edible leaves. Native to the Mediterranean, arugula is a common salad vegetable in many parts of southern Europe and has grown in popularity around the world for its peppery, nutty taste and its nutritional content. The young leaves are often eaten raw and are a good source of calcium, iron, and vitamins A, C, and K.
Arugula is full of antioxidants -- compounds that can protect against or reverse damage to your cells. Arugula also has glucosinolates. These natural substances, which give arugula its bitter taste and strong scent, may protect you against certain cancers, including breast, prostate, lung, and colon cancers.
The best to store arugula leaves is in the refrigerator. Make sure to keep the leaves cold and moist. Place them in a resealable plastic bag and using a damp paper towel to provide moisture and prevent the arugula from drying out. Fresh arugula can stay in the fridge for up to 5 days.
