Sylirican lemon

From PathfinderWiki

Sylirican lemons, presumably originating from Sylirica in Aelyosos, are used as seasoning providing a strong citrus taste. They are ground up and salted before being sealed in jars. One pound of the seasoning can season about 10 meals, with a cost of about one gold piece. After consuming a dish that contained them, the lemons' strong taste focuses the mind providing a benefit that, for a time, partially reduces any effects of confusion.1
