Yet salt can sting your eyes
Salt can inflict pain on a sore
Yet salt can heal a wound
Salt can preserve food
Yet too much salt can ruin a soup
Salt is in three-quarters of Earth's water
Yet salt can contaminate fresh water
Concentration of salt in you
Is near the same concentration of the sea
Salt can make you thirst
Yet salt water soothes a sore throat.
Salt can be your healer or salt can ruin you...
