Watercress green is a small herb of Piperaceae, which is native to the West Indies, Panama and northern South America. Later, it was introduced to China, and it was generally decorated as a potted plant, which was popular because of its bright luster and natural green color. In addition, this plant can also be used as medicine. According to the theory of traditional Chinese medicine, it can dispel wind and remove dampness, relieve cough and resolve phlegm. External use can treat traumatic injuries and fractures, so it is also an important part of Chinese herbal medicine.
