Congratulations! Yes, green is good... out. Those are stones consisting of cholisterol, bilirubin and toxic bile. (toxic bile is green, healthy bile is amber-coloured).
You should keep flushing with two weeks intervals untill no stone flush. Other wise you don't know if you are finally clean. I hope your asthma syptoms will disappear. I have never had any, so I can't say anything about it for sure. But I can say for sure that any cleaning or curing requires healthy eating too.
