One drop of that potion

(DeWitt Talmage, "The Ministry of Tears")

I am a herb doctor. I put in the caldron the Root
out of dry ground without form or loveliness. Then
I put in the Rose of Sharon and the Lily of the Valley.
Then I put into the caldron some of the leaves from
the Tree of Life, and the branch that was thrown into
the wilderness Marah. Then I pour in the tears of
Bethany and Golgotha—then I stir them up. Then I
kindle under the caldron a fire made out of the wood
of the Cross. One drop of that potion will cure the
worst sickness that ever afflicted a human soul.
