In herbs, plants, stones, and their true qualities!
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 sometime's by action dignified.
Within the infant rind of this [weak] flower
Poison hath residence, and medicine power;
For this, being smelt, [with that part] cheers each part,
