Pungent and sweet in flavor, slightly warm in nature, non-toxic. Enters the Hand-Taiyin Lung Meridian and Foot-Taiyin Spleen Meridian. It eliminates foul odors and stabilizes Huoluan (Cholera-like syndrome). It resolves pain in the heart and abdomen, and stops vomiting and regurgitation of the spleen and stomach.
It warms the middle jiao, promotes the movement of qi, opens the stomach, and stimulates appetite.
Originates from overseas countries; currently abundant in the Lingnan region, and also widely cultivated. Seedlings emerge in February; the stem is square with nodes, hollow inside, and leaves resemble those of eggplant. Physicians such as Jiegu and Dongyuan used only the leaves, not the stems.
Currently, people use both the stalks and stems because the leaves are prone to adulteration. Harvested in July.
