I don't like it, but that's not what this preparation is about, the ground that it works.


The best drug. It brings relief very quickly.

Great, the only OTC for fever, cold or the beginning of an infection


My husband's favorite drug. He believes that only this drug helps him and is the only good-tasting medicine in sachets. To tell you the truth, I have never liked drugs in sachets because of the taste. But once, being sick, my husband told me to drink. I defended myself with my arms and legs (associating such drugs from childhood) but he asked me to just try it. I tried this taste and the ones I remember (from other companies) are really heaven and earth. Is good. After others, unfortunately I had a gag reflex and never after that.
