It's the lower grade recovery medicine made by Zaidmahl House's apothecary. Lecan was thinking of having Shira look at it since he felt like it had absolutely no effect at all.
Shira took the medicine with her left hand, produced a light orb on the index fingertip of her right hand, and stared at the medicine under the light.
"Looks to be proper medicine diligently made by an ordinary apothecary. What about this."
"It didn't work when I drank it."
"Why'd you drink it. This is an ointment."
"What? Smearing recovery medicine on yourself?"
"Isn't wound salve something you apply on your wound?"
"That may be true for normal medicine, but not for magic potion."
