Seasonal Nasal Support is based on a traditional formula called Pe Min Kan Wan or Bi Min Gan Wan, known to have nurtured the health and well-being of the nasal passages, sinuses, and respiratory systems for thousands of years. This original, well-balanced formula containing a harmonious blend of magnolia flower, wild chrysanthemum, mint and other beneficial herbs is just the soothing elements your nose needs. Please note: Unlike pharmaceutical pills which are made from chemicals, it is common to require more pills per dose for herbal alternatives.
