: At low doses, it doesn't just "break" the pump; it acts as a messenger, triggering pathways that can affect cell growth, survival, and inflammation. Origins: Plant vs. Human Ouabain’s primary mechanism is its high affinity for
: This sodium buildup forces the cell to retain more calcium. In heart muscle cells, this extra calcium strengthens contractions. In heart muscle cells, this extra calcium strengthens
: It binds to and stops the pump, causing sodium to build up inside the cell.
: It is extracted from the seeds of Strophanthus gratus and the bark of the Acocanthera ouabaio tree.
: Experimental work has looked at ouabain's potential to "switch off" pain signals in peripheral neurons.
