Cough? What sort of cough?
There is now an app that can diagnose Covid by the quality of the cough. Physicians often used to diagnose this way: they could differentiate pneumonias, bronchitis, tracheitis, pharyngitis, pleurisy, bronchial asthma and tuberculosis just by the quality of the cough. A stethoscope might just be for checking.
However anyone can apply some basic principles and get quite clever in choosing the best cough remedy.
The first question is whether the cough is ‘wet’ or ‘dry’. A wet cough brings up phlegm, sputum or other fluids. A dry cough does not bring up much, or maybe tacky globs. The difference goes to the heart of lung defences and how to support them.
We have an amazing quiet mechanism (the 'mucociliary escalator') that works constantly to trap dust and germs on the airways mucus lining, and then moves them out. However if it becomes overloaded, then cough is the back-up defence.
1) If the lungs are provoked to produce more mucus, this accumulates in the airways, for example with bronchitic chest infections. Coughing is then required to heave it out and is then ‘productive’ or wet.
2) By contrast the lungs can dry out. The result is a ‘non-productive’ or dry cough. This is often seen in children, and in allergic or asthmatic conditions. More seriously it is a sign of pneumonia, pleurisy, tracheitis, or lung cancers and was a classic feature of tuberculosis.
‘Expectorants’ are remedies which help a cough on its way so that it finishes the job. In the case of a wet cough heating and drying remedies like ginger, cinnamon and garlic were favoured. Older ‘stimulating expectorants” like ipecac, squills and lobelia were emetic in larger doses.
In uncomplicated dry coughs ‘moistening’ expectorants with high levels of mucilage, such as marshmallow, the plantains and slippery elm were used.
Licorice root can help both type of cough and features in many herbal cough prescriptions.
