I love its natural ingredients and it seems to be effective. However, my son dislikes the taste and its a battle to get him to take it. Also it would have been better if it came with a syringe plus a cap for the syringe on the opening. I hate dipping the syringe in and then taking it out with the sides all sticky. Compared to alternatives, it works well enough. Its the closest I’ve found to an all natural herbal medicine I used to take in the philippines for cough, fever and flu called ASCOF made with vitex lagundi leaves. I still prefer thatbut they don’t sell those here so this is the next best thing.
