While once thought to be exclusively plant-based, scientists discovered that humans and other mammals produce an version of ouabain.
: This sodium buildup forces the cell to retain more calcium. In heart muscle cells, this extra calcium strengthens contractions.
: High doses have shown an ability to inhibit the growth of certain tumor cells, including thyroid and lung cancers. QUABAIN
: It binds to and stops the pump, causing sodium to build up inside the cell.
: 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 While once thought to be exclusively plant-based, scientists
Ouabain’s primary mechanism is its high affinity for the (
: Experimental work has looked at ouabain's potential to "switch off" pain signals in peripheral neurons. : High doses have shown an ability to
: It is extracted from the seeds of Strophanthus gratus and the bark of the Acocanthera ouabaio tree.
