Quabain

: Experimental work has looked at ouabain's potential to "switch off" pain signals in peripheral neurons.

While once thought to be exclusively plant-based, scientists discovered that humans and other mammals produce an version of ouabain. QUABAIN

Because of its role in cellular communication, researchers at institutions like ScienceDirect and Frontiers are exploring its potential beyond heart health: : Experimental work has looked at ouabain's potential

: Produced in the adrenal glands and hypothalamus, it circulates in the blood at very low levels. Levels naturally rise during physical exercise or times of high salt intake. Modern Research & Potential Uses this extra calcium strengthens contractions.

: This sodium buildup forces the cell to retain more calcium. In heart muscle cells, this extra calcium strengthens contractions.
