If your problem is in your lungs, it will be all you need, and it is completely natural with no harmful side effects.
If the problemj also involves heart function,then you need to strengthen the discs in your upper spine too, to eliminate the nerve pinch that interrupts heart rhythm.
Thanks, I’ll check out the English Ivy. Just got back from pain doctor. Spinal injection for my lower back. I have spinal stenosis also. Will have to have that operated on in the future. Lousy to get old.
