Is nasturtium officinale vegan?

Nasturtium officinale is the botanical Latin name for watercress, a fast-growing aquatic or semi-aquatic perennial plant in the mustard and cabbage family Brassicaceae. It grows naturally in clear, shallow streams and springs, and it is also widely cultivated in flooded commercial beds or hydroponic systems. The plant's hollow stems and leaves are harvested, rinsed, and used either whole or processed into dried flakes, powders, juices, and botanical extracts. On ingredient lists, it typically appears in packaged salad greens, vegetable juices, pestos, soups, seasoning blends, and dietary supplements.

nasturtium officinale is vegan because it is exclusively of plant origin. The cultivation, harvesting, and physical processing of watercress do not involve any animal sources or animal-derived processing aids. Whether it is included as a raw leafy vegetable, a dehydrated herb, or a liquid extract, nasturtium officinale consists entirely of botanical matter and is always suitable for vegans.
