Review: Best Cough Syrup Ever! - This is the best working and strongest cough suppressant there is, besides the one you need an RX for from a physician. We’ve been using it for a very long time with great success. Don’t be fooled by the generic brands as they don’t have the same ingredients! Delsum is more expensive but you get what you pay for, in this instance.
Review: Most effective cough suppressant - Have used for years. Calms my cough like no other. Orange flavor is good.
