Poisoned Blood

Hemlock, the fires of pain,
The poisoned lips of Henbane.

Strong and powerful, Aconite,
Belladonna, send us into flight.

Opium, time and space bent like a horn,
The blessed apple of thorn.

Cinquifoil, shrub and flower
Mandragora, causing death to come to power.

This is a simple poem I wrote that I believe sums up the strengths of these herbs. I guess you could use this to help focus the powers of a spell if its for a more malicious means.
