Water of Life

What's with me I give to you The fuel for your life; I bring back the norm in those with the flu, And put you on the path to strive. I am with the flow of the earth I am of the most abundant out there; Always in someway near the turf, And I definitely need to be spread. I'm beautiful and heart warming But at times I am destructive; At the mercy of the air that's swarming, So against my will I take part in something intensive. I will never run out of something so necessary If so comes the time I'm sure it will be slow; Because I am water a source so legendary, And like time I will continue to flow.
