My mom is 85 and has asthma and copd for 20 years now. Both started getting worse the last couple years and I could tell the docs couldn't or wouldn't do much to help her. I discovered in my research on youtube that peppermint tea and organic raw honey when drunk daily will clear mucus from lungs. She started using these two simple remedies 6 months ago & her doc told her after 4 months of drinking this that her lungs were clear of mucus. For the first time in years, she (doc) heard no wheezing or rattling noise.
My mom drinks a cup in the morning and later in the day. Whenever she feels like a cold or something is coming on, she doubles the tea bags and honey for safe measures, and so far, praise God, it seems to help war off intruders.
