Alchemy don't needs to be magical, just a slight bit fantastical.
Something like a pain blocker could be developed, IMO.
Hell, we have ancient smiths in our history who could forge steel which was happened to be reinforced by carbon nanotubes.
Yup, the big sensation of material engineering was something a group of smiths accidentally managed to reproduce during their "primitive" steelmaking procedures.

If you are referring to Damascus Steel, it wasn't alchemy that made it strong, it was a mixture of plant matter that happened to have rough, naturally forming nanotubes.
