We received this product free with our last order. My husband who sometimes can\'t catch his breath properly at times, or take in a full breath, when this happens it can last for hours and can be very frustrating for him. He was born with a collasped lung, so we are not sure if this is related to his problem with breathing, but i dont know anyone else who has this problem. Anyway he tried this product when he cant breathe prople, and he swears it works. He thinks it relaxes his airways and enables him to take in a full breath. So anyway Thank you for offering a us a free product we would of never taken the chance on normally, it helps him and he is very happy about that.
