So I definitely was skeptical about giving this a try but my friend who is a all natural person. Swears by this stuff. I had came home from Washington and felt terrible. I called my friend and she sent me a picture. I looked it up on Amazon and after reading the reviews. I ordered my bottle. Let me tell you, I used it for three days straight and whatever I had going on was out my system. My daughter had a cough, I gave it to her also. My only drawback is the taste. Me and her would have to pump ourselves up to take it but it's definitely worth it. Now I take if I feel a tickle in my throat or a slight cough. I don't take any chances. This will stop it before it gets started. It works, that's it, that's all.
