ManukaGuard Throat & Chest Syrup soothes and protects the throat while helping the body recover. Research into the effects of manuka honey indicates that it s most effective when correctly diluted and combined with supporting extracts. It has been well documented that honey alone helps suppress coughing. But when combined with four botanical extracts – ginger root, olive leaf, elecampane root, and licorice root – plus a dash of apple cider vinegar, manuka honey delivers a powerful drug-free solution to soothe the throat and control a cough.
