Coconut water is sterile, isotonic with body fluids, and contains electrolytes similar to blood plasma. In emergency situations where medical supplies were unavailable, doctors successfully used young coconut water intravenously to rehydrate wounded soldiers. However, this is only a short-term emergency substitute - coconut water lacks proper proteins and has other differences from real plasma. It should never be used in modern medical settings except in absolute extreme emergencies without alternatives.
