Tonics:

Invigorating: this tonic provides a +2 medicine bonus to strength.
Relaxing: this tonic provides a +2 medicine bonus to dexterity.
Toughening: this tonic provides a +2 medicine bonus to constitution.

I approve, but could do with the option to provide penalties as well.

Drugs:
When making a drug, choose a specific poison (i.e. rattlesnake venom) or disease (i.e. the Blackwater Taint). The drug provides the one drinking it a +5 medicine bonus on his next save against that disease or poison.

While complete versimilitude is a noble goal, one cure for one disease and one antidote for each posion doesn't really help out game mechanics. I think having a generic "disease cure" and a generic "antidote" is the way forward, providing a +2 (or higher) bonus on saves and allowing you to make a new save if you have the disease. Perhaps specific drugs could allow higher saves for their named disease, but act as a generic drug for all other diseases. Makes it less of a downer if you've got The Hillbilly Itch*, and your party doc only has his patented Blackwater Taint cure.

*I just made that up, but it sounds like it could be either inconvenient, or majorly unpleasant just with a light-hearted name. Perhaps dex drain, with secondary con?
