In Puerto Rico and the Caribbean, the leaves are decocted in water to make a tea to treat flatulence and rheumatism. A tea made from the rhizomes and roots is taken to treat urinary problems, kidney stones, nephritis (kidney inflammation), inflammation of the urethra, as a diaphoretic (to promote sweating), as a diuretic, and as an emmenagogue (to promote menstruation). The acidic juice from the young rhizomes (stems) is taken to treat diabetes, bronchitis, headaches, colds, and fever. The roots are decocted in water to make a tea to treat gastritis, liver problems, and snakebite. The juice from the flowers is taken against internal parasites and for the treatment of vaginal infections (Berdonces, 2009; Liogier, 1990, 1974; Morton, 1981; Nuñez-Meléndez, 1981).
