This is concerning Heart disease and lung problems. There is one non-herbal, non-invasive Yoga technique called " Pranayam". I had a triple bypass 13 years ago and had just started to have lung problems. After practicing this Yoga, I felt the difference next day in Asthma and breathing. Please save your life, Go to youtube-Baba Ramdev, Asthma or Heart disease. Baba Ramdev is teaching to millions on TV each morning in India for free. God Bless. If you have any questions e-mail me.
