Judy,
Green drinks can be excellent for people that experience all types of problems, including the ones that you mention. I would not say that they are a cure but rather a powerful nutritional tool to support the body. They are rich in magnesium, enzymes, trace minerals, anti-oxidants, and other nutritional factors that can be very important in helping the body cope with inflammation and aiding in muscle and bronchial relaxation. There are literally dozens of nutrients and nutritional complexes that could be very beneficial. For the sake of space, I will post a link to an article that mentions several nutrients that can help to support healthy lung function:

Most people benefit when they use a quality air filter and ionizer and when they perform a colon cleanse, liver/gallbladder flush, and a parasite cleanse:
