Coconut water is the liquid found inside unripe coconuts that eventually forms the familiar white pulp as the fruit matures. Natives have consumed coconut water for centuries, knowing it is helpful for building a strong immune system. In addition, coconut water may be useful for hydrating the body due to high levels of electrolytes. Coconut waters provides a variety of medicinal uses and is an inexpensive, natural way to supplement your diet.

Coconut water is often used to re-hydrate the body during and after exercise, according to the Texas Department of State Health Services. The coconut water takes the place of sugary electrolyte drinks, supplying high levels of potassium, magnesium, sodium, calcium and phosphorus. In addition, it is low in sugar, fats and cholesterol. The Food and Agriculture Organization of the United Nations has received the first patent for the UN to produce a sports drink with coconut water.

Coconut water is sterile and can be used to eliminate parasites and worms in the intestines, says Bruce Fife in “Coconut Water for Health and Healing." Mixing a glass of coconut water with a teaspoonful of olive oil for three days will help kill off parasites and allow them to pass from the system. Consult your health practitioner before doing this to make sure your problem is parasites and not some other condition that may mimic the symptoms.

Because coconut water is sterile when it comes out of the coconut, it can be used to disinfect wounds, according to Fife. In addition to being sterile, he adds that coconut water is almost identical to human plasma chemically and can be used as a universal donor for blood transfusions in emergencies.

Due to its high quantities of potassium, coconut water may help alkalize urine and dissolve certain types of kidney stones. Dr. Theodore Baroody discusses in his book "Alkalize or Die" how foods high in potassium are excellent sources of nutrients that help create an alkaline-forming environment in the blood and urine, altering the body's pH and dissolving various calculi.

Coconut water may be helpful for reducing vomiting and nausea, according to Fife. It is especially helpful in replacing fluids lost during vomiting in diseases, such as typhoid, malaria and severe intestinal flu.
