For the past several years, cardiologists have been beating the drum for lower blood pressure. We have all seen the studies and/or articles that have challenged the notion that the old cut-off of 140/90mmHg is too high for diagnosing high blood pressure. The medical community even went so far as to coin the new term "pre-hypertension" to describe individuals with a blood pressure over 120/80mmHg.

The suffering cougher goes unblessed and often feels isolated as people flee for cover hoping not to inhale any aerosolized infectious particles. Such defense mechanisms are not looked down upon in today’s era of germ avoidance, but what defense does the cougher have against the seemingly never ending cough?

An acute cough generally goes away within three to four weeks for a child and within eight weeks for an adult. There are many causes of acute cough but the most common one is the common cold. Other causes include sinus infections, flu syndrome, other upper respiratory infections and ear i...
