I have created quick and easy to use herbalism rules for WFRP3. You can find the document, WFRP3 Herbalism and Pharmacy , from my Kaleva Hammer -site. There is also .zip which has some example herbs and concoctions. Example cards have one medicine, one poison and one drug. Didn't have energy to create more examples, but these rules should make creation or converting of other herbs and concoctions more easy.
Rules include needed skills (which had to be little expanded, so careers like Apothecary could actually make something), skill checks, rules for herbs/plants, making the concoctions and finally also for ready concoctions. Then some more expanded rules for narcotics and poisons.
