There is no such thing as the most effective cure for any disease. Lanternwort is mainly used for the treatment of heartburn and insomnia (symptoms of heatiness and insomnia in the heart), pediatric fever, night crying and other conditions. Lanternwort has the effect of diuretic and diaphoretic (improving the problem of incomplete urination and small amount of urination), clearing the heart and lowering fire. It can be used for treating heartburn and insomnia, pediatric fever, night crying, mouth and tongue sores, jaundice due to dampness-heat, edema, gonorrhea (increased frequency of urination, astringent and painful dribbling), and dysuria (inability to urinate smoothly). Lampsbane is forbidden to be taken by those who are suffering from deficiency and coldness in the lower Jiao and urinary incontinence. If you need to use the drug, you should use it under the guidance of a traditional Chinese medicine practitioner, and should not purchase the drug for use on your own.
