Alack, ’tis he! Why, he was met even now

Cordelia
Alack, 'tis he! Why, he was met even now
As mad as the vexed sea, singing aloud,
Crowned with rank fumiter and furrow-weeds,
With hardocks, hemlock, nettles, cuckooflowers,
Darnel, and all the idle weeds that grow
In our sustaining corn. A century send forth.
Search every acre in the high-grown field
And bring him to our eye.
Soldiers exit.
What can man's wisdom
In the restoring his bereavèd sense?
He that helps him take all my outward worth.
Doctor
There is means, madam.
Our foster nurse of nature is repose,
The which he lacks. That to provoke in him
Are many simples operative, whose power
Will close the eye of anguish.
Cordelia
All blest secrets,
All you unpublished virtues of the earth,
Spring with my tears. Be aidant and remediate
In the good man's distress.  Seek, seek for him,
Lest his ungoverned rage dissolve the life
That wants the means to lead it.
