In WW2 soldiers were injected with coconut water

Called by some “the sports drink of mother nature” coconut water is a natural isotonic (it contains similar concentrations of salt and sugar as in the human body). We all know coconut water is full of goodness and a nutritious drink but did you know you can even inject it?

Saline solution was hard to come by in World War 2 so in documented cases in Thailand, the USA and Honduras coconut water was used instead.

Although substituting coconut water for saline is not recommended by physicians today, it was a common practice for during the Khmer Rouge regime in Cambodia from 1975 to 1979.

According to thestudentscientist.org “the bottom line is that coconut water is not identical to human plasma. Therefore, only in extreme situations would it be an acceptable substitution.”

It also has a significant electrolyte content which may explain why many Jamaicans swear by it as a cure for diarrhoea.
