Usually, with the original Listerine products I will have that stuff in my mouth for only a few seconds and I want to spit it out right away because it's so strong I just can't stand it! The original Listerine contains 26.9% alcohol and the Naturals only 21.6%, which is the same percentage in the majority of their other mouthwashes. Plus the active ingredients and percentages are the same throughout their line of antiseptic products. I LOVED IT! It really wasn't as harsh as their other products though it will still give you that Listerine tingle. The hint of mint was subtle and it left my mouth feeling clean, and breath fresh for long after. To me the aftertaste didn't linger for long, which is another thing I wasn't too fond of in their other products. The only thing I wish it had in it was fluoride. But they DO have a Listerine Naturals with fluoride I found out so I'll be buying next!
