Very interesting....my oldest son who is 21, has very bad asthma. When he was small, I gave him albuterol breathing treatments and cromolyn sodium treatments every 4 hours. Literally for about 3-4 years. He was a very bad asthmatic, blue at times. It does work. I have always wondered about it...why I never hear about it anymore. but it must have helped him some, he is still here! <img src="i/expressions/face-icon-small-smile.gif" border="0">
