Cyperus is known as a carminative and sedative. The root of the Adrue (Cyperus) plant contains compounds that have an overall calming effect on the body and has been used for centuries in African and Asian medicine systems. The aromatic properties of the herb alone cause a feeling of warmth to be diffused throughout the whole bodily system. Sometimes it is reportedly used as an aid to help induce vivid dreaming due to its calming and sedative effects, but there is little data on the subject at the time of this writing.
Cypreus has a bitterish, aromatic taste, recalling that of Lavender, and the odor of the fresh tubers has been likened to that of the Sweet Sedge, Calamus aromaticus. Cyperus articulatus (Adrue) is the tuberous rhizome of the Guinea Rush a tall sedge, common in Jamaica, and on the banks of the Nile. The nuts are quite hard and are generally soaked in water for a few hours before they can be eaten.
