As part of a university-wide project to explore Shakespeare's classic play, Romeo and Juliet, from a variety of perspectives, we presented an interdisciplinary talk to our university community on the chemistry of the potions and poisons referenced in Romeo and Juliet. To draw our multidisciplinary audience in and to teach about forensics as well as pharmaceutical herbs and chemicals, our presentation was given from the perspective of how a modern crime scene investigator would approach the famous play's final death scene without any prior knowledge of the situation. We described how if an autopsy of Juliet's body had been done, it might have revealed the presence of the chemicals, hyoscine and atropine, that come from the plant, Atropa belladonna. The autopsy could reveal whether or not the Friar had truly set out to sedate Juliet, or if he had attempted to kill her. An autopsy of Romeo's body might have revealed the presence of aconitine from the plant, Aconitum napellus. Through this approach of using a classic story to teach about chemistry, we were able to introduce basic ideas about forensics and pharmacology, emphasizing the importance of dose when determining the effect of a drug on the human body.
