Something I don't know much about

Got a phonecall yesterday from someone who has just been diagnosed with pleurisy. Have booked them a session of reiki but has anyone used any herbs for this complaint? - no history of chest infection that they can remember from last few months - possibly caused by breathing in wood dust and/or filler - presently awaiting feedback from x-ray, which being a holiday they will have to wait till Tuesday now. Bet if they were a 'really useful' MP or a member of our ever scrounging royals the result would have instantaneous etc etc
