Haven't tried the Zarbee's because I'm nervous about giving melatonin to a small child. But Maty's children's cough syrup worked a treat. It's also honey based, with lemon peel, zinc, cloves, and other kitchen herbs, and I thought it tasted pretty good. My daughter, though, said YUCK! It's very thick, so that may have been a bigger issue than the taste. But an hour later she was no longer coughing, and she slept until it wore off five hours later. They have an adult formula, too, that I will try next time I need to.
