Question

Is it true that the liquid inside young coconuts can be used as substitute for blood plasma?

Answer 1

Coconut Water is Used in Blood Transfusion

Coconut water is almost identical to blood plasma and this makes it easy to use for blood transfusion. In cases of emergency coconut water has been used as an intravenous hydration fluid instead of the standard IV fluid. During World War II many wounded soldiers were saved in the Pacific because of emergency transfusion using coconut water as plasma.
