When the wind blows, the pods of the bladder senna plant move and clink, producing a metallic sound that is believed to frighten wolves. Great botanists of ancient times forgot this plant, which does not encourage its use because of its disgusting smell and bitter flavor. Today, it is still seldom used, despite having some usefulness as a mild laxative.
Healing Properties and Warning
Its leaves contain an essential oil, coluteic acid, mineral salts, and vitamins. They have laxative and mildly diuretic properties, being sometimes employed as a substitute for tinnevelly senna. The laxative property of bladder senna leaves is mild, less intense than that of some other laxative plants. However, they have diuretic and depurative properties, making them recommended for people suffering from constipation and excess uric acid.
WARNING! The seeds of this plant, which grow inside the pods, look like lentils. These seeds are mildly toxic and may produce vomiting.
