Lungwort is the mature fruit of Lungwort, family Solanaceae, which has high nutritional value. From the perspective of traditional Chinese medicine, its medicinal properties are bitter and cold, with the effect of clearing heat and detoxifying, reducing swelling and dispersing knots, producing fluid and quenching thirst, and diuretic, and can be used for sore throat, sore mouth and tongue, scrofula, gall disease, lung dryness and cough, edema, and urinary discomfort. Lungwort is rich in vitamins, alkaloids, alpha-carotene and other components. Modern pharmacological research has confirmed that it has the effects of cough suppressing and resolving phlegm, reducing nociception and analgesia, regulating blood sugar and blood pressure, antioxidant, tumor prevention, anti-inflammatory and antiseptic. Because lobelia is bitter and cold, it is generally not suitable for people with a cold spleen and stomach.
