Yes, arugula is low histamine. Also known as rocket, arugula is a peppery leaf commonly used to add depth to salads, but it can also be mixed into omelets, swirled into stews, or blended into pesto. The leaves are a powerful antihistamine food, rich in anti-inflammatory phytochemicals like flavonoids and glucosinolates, much like the other members of the brassica family. Both baby arugula and the fully-grown version are also potent antioxidants, and may even aid in detoxification.
