Living self-aware is not only being mindful of what you think and experience but also what you eat and keeping the body healthy too.
Naturally, we have more choices about ingesting environmental pollutants than we when it comes to the air we breathe. Airborne bacteria like Tuberculosis is often passed on unnoticed or fungus in soil and sand are also passed on undetected until a cough starts. Second-hand tobacco smoke is another example. These unseen pollutants in the air affect the lungs dramatically and 
especially over time.
In traditional Chinese medicine, long-standing grief affects the lungs.
Recently I found myself buying three bottles of Mullein. Something must be up with my lungs. It’s my body’s way of getting my attention.
Mullein is good for influenza A, and is analgesic, antibacterial, anti-cancer, antihistamine, anti-inflammatory.
Mullein is nutrient-rich herb and is high in calcium, magnesium, phosphorous, iron, niacin, potassium, riboflavin, thiamine, Vitamin A, and amino acids.
Mullein has demulcent, emollient and astringent properties and is useful in lung complaints and bleeding of the lungs and bowels. 
The whole plant seems to possess slightly sedative properties.
Mullein has been used by herbalists as a remedy for the respiratory tract, particularly in cases of irritating coughs with bronchial congestion. Mullein a valuable destroyer of disease germs and removes mucus from the lungs and organs too.
When we ingest toxic foods such as dairy and foods that are more acidic in nature they cause a mucoid lining to develop in the intestine, which makes it difficult for nutrients to pass through its wall and feed the body. Mullein is said to be of value in diarrhea, from its combination of demulcent with astringent properties. This combination strengthens the bowels at the same time.
It’s wonderful for lung inflammation from all kinds of irritants and pathologies. Take later in the afternoon or early evening because of its sedative effects will relax you.
