There is little difference except mastic means 'from plant origins'.

Mastic gum is mainly used for treating gastrointestinal ulcers, poor circulation, yeast infections, and breathing problems. Mastic gum seems to have little or no side effects for most people. Mastic is a part of a tree, so the only problem would be if you are allergic to certain trees, you may be allergic to Mastic Gum.

Mastic is an adhesive not a flooring some manufacturers say it can be used on floor tiles how ever I would not recommend using mastic on a floor as it would take forever to cure
