> About a hundred sixty years after Dr. Salter’s book was published, a review of studies was performed to see if coffee had any true impact on lung function and asthma. The authors wrote:
> “Caffeine is found in coffee, tea, cola drinks and cocoa. Caffeine is a drug that is very similar to theophylline. Theophylline is a bronchodilator drug that is taken to open up the airways in the lungs and therefore relieve the symptoms of asthma, such as wheezing, coughing and breathlessness. Scientists are interested in finding out whether caffeine has the same effect on the lungs as theophylline.”2

> Caffeine is a methylxanthine. It falls into the same family of medicine as theophylline, a strong bronchodilator that was a top-line asthma remedy during the 1970’s through the 1990’s. I was chronically dependent on theophylline from the mid 1970’s until 2007.
Who knew? And it’s from 1990.
