Ask your LOR but my psak FWIW is mutar lach mutar lach mutar lach. At least for the medicine. The cough drops might be more of a shayla. And whether or not there is grinding doesn’t make much of a difference. The rabanan made a takana whether there is grinding or not. Most ppl nowadays don’t grind their own medicine yet we still follow the issur drabanan of refuah.
