The Benefits, Nutritional Value, and Dietary Precautions of Potherb Mustard (Snow Cabbage)

Potherb mustard (Brassica juncea var. multiceps), also known as snow cabbage, is a variety of mustard in the Brassicaceae family. Its leaves are deeply lobed with serrated edges, and it is highly cold-tolerant. It is grown throughout both northern and southern China, and gets its name because it can stay green even after being covered in snow. It can be eaten as a fresh vegetable, but is also commonly pickled into snow cabbage, making it an important ingredient in many regional dishes.

From a nutritional standpoint, potherb mustard is rich in dietary fiber, vitamin C, carotene, and minerals such as calcium and iron, while being low in calories. Its dietary fiber promotes intestinal movement and helps with bowel movements, making it a good supplement for people whose daily diet lacks coarse fiber; antioxidant components such as vitamin C help maintain normal body metabolism.

Traditional Chinese medicine holds that potherb mustard is pungent in flavor and warm in nature, and has the effects of stimulating the appetite and aiding digestion, as well as detoxifying and reducing swelling. Once pickled, potherb mustard is tangy and refreshing, and is often cooked with ingredients such as shredded pork, winter bamboo shoots, and yellow croaker, enhancing both the flavor of the dish and the appetite; fresh potherb mustard, after being blanched, can be stir-fried or made into soup, with a crisp, tender, and fragrant taste.

It should be noted that pickled potherb mustard has a high salt content, so people with high blood pressure, kidney disease, or those who need to control their salt intake should eat as little of it as possible; freshly pickled snow cabbage has a relatively high nitrite content, so it is recommended to wait until it is fully matured before eating, and to consume it in moderation. In addition, people with a hot constitution who are prone to internal heat should not eat large amounts of it. For daily consumption, light pairings and a balanced diet are the safer choice.
