“Did you know mullein leaf helps to detox the lungs from tar, mucus and phlegm?” asks text on a graphic posted on Facebook. “It opens up airways, fights asthma and lung issues.”
The graphic is headed “LUNG CLEANSE”.
Are these claims about its “lung cleansing” properties correct? We checked.
No evidence supports claims
He said there was “no scientific evidence available” to support them.
The best way to keep lungs healthy was to “avoid exposure to harmful substances such as cigarette and other smoke, vaping, and polluted environments”.
Asthma ‘serious, potentially life-threatening’
According to the Mayo Clinic, a nonprofit American academic medical centre, asthma is a condition in which your airways narrow and swell and may produce extra mucus. “This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath.”
It can be caused by environmental or genetic factors.
Raine said asthma was a “serious, potentially life-threatening disease” with “scientifically well-established treatments that have been approved by major respiratory medicine societies around the world”. Mullein leaf is not one of these treatments.
“Recommended treatment strategies improve quality of life, decrease hospitalisation, and prevent death from acute severe asthma.”
If you have lung problems see a doctor who can diagnose you and prescribe safe, effective treatments.
