There are ten things that start with "T" that can cause ear pain:
teeth
tongue
tonsils
thyroid
tempera-mandibular joint
tenth cranial nerve
tensor veli palatini
and three others I can't remember off hand.
How many problems with any of those can be cured by sticking garlic in your external ear canal? None.
By the way I'm not dismissing the placebo effect. A placebo is quite powerful. The person receiving it just has to believe it's an effective treatment.
A proposed treatment always has to be compared to a placebo because of the powerful placebo effect. If a treatment has no better outcome than a placebo it isn't doing anything useful.
