You have not specified the particular type of lung infection you suffer from. However, since the third century B.C. herbalists have used liquorice to treat various lung infections like asthma, bronchitis, and other lung and chest infections. Liquorice contains anti-viral compounds that activate the body's own anti-viral constituents. Besides being an effective and soothing herb it also tastes nice. However, over consumption has a laxative effect.
Peppermint is also found to be a helpful decongestant in treating bronchitis and other respiratory infections. Simple sugar also has properties that enhance the natural defense system, thus it potentially helps delay or prevent the onset of bacterial infections. Most lung infections are short-term and not dangerous, however it is important that you consult your doctor for a diagnosis, as lung infections like tuberculosis, pleurisy, histoplasmosis and aspergillosis can have a serious and even fatal effect on the body if not detected and treated early.
Asthma can be treated using honey; by inhaling it from a jar held beneath your nose. This has a soothing effect on the air passages. A teaspoon of ginger mixed with fenugreek is also useful to treat asthma. Following a diet that contains more alkali forming foods than acid forming foods also helps. Figs (three or four a day) help drain phlegm. For people who are in their early stages of asthma, a perfect home remedy is to boil 8-10 cloves of garlic in ½ cup of milk and consume it before going to bed.
