Origin:

Watercress belongs to Cruciferae, and watercress belongs to the whole plant of watercress, a perennial aquatic herb. 20-40 cm high, with many branches and roots on the nodes; The leaves are odd pinnate compound leaves; Leaflets 1-4 pairs, ovoid or broadly ovoid, terminal leaflets entire or with some wavy teeth. Racemes are terminal, with white flowers and usually recurved pedicels. The whole watercress is light green, and the one near white is the best, so it is called "white bone watercress".

At the end of ancient literature, watercress was eaten by people in the south of China, but it was only nearly a hundred years. The modern giant Chinese medicine dictionary has income.

The origin of the name watercress is that a Portuguese sailor suffered from lung disease and lived in Japan one hundred years ago. People thought he was dead, but he survived because he ate an extra portion of vegetables to satisfy his hunger. After living in Macao, I transplanted this dish, and since then I have had this dish in rural areas of Hong Kong, Macao and Guangzhou. This dish was introduced to China by the Portuguese, so it is called western food. Cantonese people have a good impression of western food, which is considered as a vegetable for clearing away lung heat. When cooking, boiled watercress is a kind of home-cooked soup, which can clear away heat and moisten the lungs, and is more suitable for dry weather after winter. Cooking is also delicious. In case of lung heat, dry mouth, sore throat and cough, it is often used to cook duck kidney, or add Siraitia grosvenorii and pork, or cook soup with fish, which is delicious.

This dish is only available in Guangzhou, Hongkong and Macau in China. Shallow ponds can be planted with rough stems, but there are many leeches in shallow ponds, so they should be carefully cleaned before eating. The stems in autumn and winter are tender, but if they are overcooked, they will be tough and bitter.
