Cough, Throat & Chest 咳嗽·咽喉·胸肺 traditional evidenceWhat the evidence says:

How to make it
2–3 whole fruits steeped in just-boiled water until they swell open, 10–15 min. Sip. Short courses of a few days only.
Why it works
It swells into a mucilaginous mass — the demulcent coating is the plausible mechanism, the same idea as honey.
Classical source
胖大海 is a late arrival by sea trade — not in the Shennong Bencao Jing.
Cautions: Not for prolonged daily use — it is cold and can cause loose stools and poor appetite. Contains 甘草 here: skip that pairing with hypertension, heart failure, kidney disease, or on diuretics or digoxin. Sudden voice loss lasting over 3 weeks needs an ENT review — hoarseness is a laryngeal-cancer red flag in smokers.
