I published this idea 2012, to be read and confirmed by all Dr.s. HIUS totally clears asthma – so inhalers are defective, criminal medicine for 7 years: get your medical fees back – 10 million for ever death.
I use an 8W 1MHz ultrasound massage device – medically licensed for home, unsupervuised use. You want ½ a minute of HIUS t oeach side of the chest. Maybe only 1 time, 3 if you fee lthe need.
