side effects, nutrient depletions, herbal interactions and health notes:
• potassium; Some beta-adrenergic blockers (called “nonselective” beta blockers) decrease the uptake of potassium from the blood into the cells,1 leading to excess potassium in the blood, a potentially dangerous condition known as hyperkalemia.2 People taking beta-blockers should therefore avoid taking potassium supplements, or eating large quantities of fruit (e.g., bananas), unless directed to do so by their doctor.1
• Pleurisy root As pleurisy root and other plants in the Aesclepius genus contain cardiac glycosides, it is best to avoid use of pleurisy root with heart medications such as beta-blockers.32
