Tiger milk mushroom: for a cough that keeps coming back?
Tested for nasal allergies. Not for cough.
Tigrox sells tiger milk mushroom (Lignosus rhinocerus) as lung “nurture” for a recurring cough. Short answer: one double-blind trial found it eased allergic rhinitis — a blocked, runny nose — over 30 days, though only in the half of people analysed per protocol. We found no trial of it for cough.

What the research shows
Grades are calculated from the studies listed, by fixed rules.
- Tiger milk mushroom (TM02) eases allergic rhinitis symptomsPromising
One double-blind trial: nasal symptoms improved more than placebo over 30 days — but the result comes from the 56 of 108 people analysed per protocol, not everyone who started.
- Tiger milk mushroom “nurtures” the lungs so a recurring cough stops coming backNo real evidence
The ad said “Cough keeps coming back? / Maybe you've been rescuing your lungs instead of nurturing them. / Cough syrups are rescue. Tiger Milk Mushroom is nurture.”
