Ouabain hormone. Computer-generated model of a molecule of the hormone ouabain. It plays a key role in human hypertension (high blood pressure). Colour-coded atoms are represented as spheres: carbon (blue), oxygen (red), hydrogen (white). Ouabain has been identified from two rare African plants, used in Masai arrow poison. Ouabain in the blood was first identified by Doctors Hamlyn and Blaustein in 1991. It is produced by the human adrenal glands. Ouabain raises blood pressure by inhibiting sodium transport from cells. Future drugs that lower ouabain hormone in the blood may prevent hypertension, heart attacks and strokes.
