These amazing seeds may cause a low blood pressure reaction due to the formation of potassium thiocyanate (also known as thiocyanic acid), which is a potent blood pressure-lowering agent. the part of the casual blood pressure that ieflects the physical, emotional, and metabolic activity of the patient at the time (Alamet al., 1943). Furthermore, the pharmaceutical industry uses thiocyanic acid as a raw material for antibiotics, chemotherapeutic drugs, and thyroid medications. Just like potassium, too much magnesium can be lost in urine due to diuretic use, leading to low magnesium levels.
