I get asthma and if I get a cold it goes straight to my chest. One day I had a tap in my nose – it was streaming! I took one Leapfrog in the morning and one in the evening, and another one the next morning. By the end of that day it was gone, it had cleared up. It was like somebody had turned the tap off! Leapfrog is just amazing, and I wouldn’t be without it now. It will forever be in my cupboard! I’ve recommended it to many friends.
