How does Shakespeare use imagery in this excerpt from Romeo and Juliet?

Romeo and Juliet?


I must up-fill this osier cage of ours


with baleful weeds and precious-juiced flowers,


The earth that's the nature's mother is her tomb;


What is her burying grave that is her womb,


And from her womb children of divers kind


We sucking on her natural bosom find,


Many for many virtues excellent,


None but for some and yet all different.


O, mickle is the powerful grace that lies


In herbs, plants, stones, and their true qualitites:


For nought so vile that on the earth doth live


But to the earth some special good doth give,


Nor aught so good but strain'd from that fair use


Revolts from true birth, stumbling on abuse:


Virtue itself turns vice, being misapplied;


And vice sometimes by action dignified.


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.
