Pineapple Juice and Cloudy Apple juice on it's effects on breathing

[jerry3571]

Hi, My Mum has MND and it is known in the Community that Pineapple Juice/Bromelian can have an effect on thick mucous which can build up in the throat, mouth and lungs.
My question is, has this been used in other areas of Respiratory Medicine where thick Mucous is an issue? (be minded Pineapple can interact with some drugs like Blood thinning drugs)

Also, I have asthma and I cycle a fair bit. Since using Cloudy Apple Juice in my water bottle I have little trouble with Asthma on this bike. I also use it otherwise too and with allergic reaction. Seems it has a pronounced effect.
Has there been any research on this? Also, feel free to try.
Use your usual Meds of course with this :)
