Potassium, is important for a healthy nervous system and a regular heat rhythm. It helps prevent stroke, aids in proper muscle contraction, and works with sodium to control the body's water balance.
This mineral is important for chemical reactions within the cells and aids in maintaining stable blood pressure and in transmitting electro-chemical impulses. It also regulates the transfer of nutrients through cell membranes. The function of this mineral has been shown to decrease with age, which may account for some of the circulatory damage, lethargy, and weakness experienced by older people.
Signs of potassium deficiency include:
abnormally dry skin
diminished reflex function
fluctuations in heartbeat
high cholesterol levels
low blood pressure
muscular fatigue and weakness
nausea and vomiting
proteinuria (protein in the urine)

Herbs containing potassium include:
Kidney disorders, diarrhea, and the use of diuretics or laxatives all disrupt potassium levels. Tobacco and caffeine reduce absorption of this mineral.
Potassium is needed for hormone secretion. The secretion of stress hormones causes a decrease in the potassium-to-sodium ration both inside and outside the cells. As a result, stress increases the body's potassium requirements.
