I have a very sensitive throat accompanied by a stubborn cough and sticky phlegm. There were days where my coughing was so painful that I couldn’t focus on my work. I have been having this condition for many years until my friend recommended this product to me. I have been taking Lignosus for the past one month. And my cough almost stops. And my chest doesn’t hurt anymore and my lungs become healthier and free from phlegm. I am truly amazed by these results!
