Wouldnt be without it.
Ive been using Lignosus for 2 years. I use one sachet a day mixed in a little water. Taste is nice and my breathing is always clear. I order 6 boxes at a time so its more economical and i only need to order twice a year. I am a smoker so i use it as a maintenance routine. My blood oxygen level is constant at 99 to 100%
