Sinus Breakup has an immediate, dramatic, and direct impact on the sinus. It is an extremely pungent formula with aromatic compounds that produce vapors that open and dilate the sinus passageways in order to drain them, deepen breathing, and help to kill microbial inundation. This formula helps to thin thick and infected mucus and expectorate it out. Repeated doses over part of a day can help maintain breathing and sinus drainage and therefore shorten the time to healing.
