Nervine

 Over 30 years ago, my mom worked for a subsidiary of Miles and any medicines they made, they gave away free in a company store.

I had read about Nervine in a Philip K. Dick story, naturally.  When I spotted this, I though t it would make a nice souvenir.

Mom let me have a bottle as long as I promised never to take any.  This formulation from the late 1980s has Diphenhydramine HCl as the active ingredient.
