He says:
> "Within the infant rind of this small flower
> Poison hath residence, and medicine power:
> For this, being smelt, with that part cheers each part;
> Being tasted, slays all senses with the heart." (Act 2, Scene 3)
He argues that even in something as seemingly harmless as a flower, there can be both positive and negative aspects, just like in human nature. This metaphor helps illustrate the Friar's own philosophical perspective, and foreshadows the tragic events to come in the play.
