My husband was diagnosed by a pulmonologist as having asthma or possibly COPD. He was given a prescription for a steroid inhaler. After 4 days, his symptoms were so bad he had to stop taking this medication. While it helped his lungs feel more open, he developed hoarseness and sleep deprivation, blurred vision, shakiness and rapid heart rate. When he started on Lignosus, it took close to three weeks but he did stabilize and did not use the inhaler at all. He has continued to improve over the past two weeks. We are looking forward to continued improvement using this product. He feels good when hiking and has less congestion.
