Johannis Baptistae Von Helmont

From von Helmont's Ausgang der Artznen-Kunst
At the beginning of the 17th century, von Helmont, the 
Belgian alchemist, while experimenting with the root of A---, touched it to the 
tip of his tongue, without swallowing any of the substance. He himself describes 
the result in the following manner:
"Immediately my head seemed tied tightly 
with a string, and soon after there happened to me a singular circumstance such 
as I had never before experienced. I observed with astonishment that I no longer 
felt and thought with the head, but with the region of the stomach, as if 
consciousness had now taken up its seat in the stomach. Terrified by this 
unusual phenomenon, I asked myself and inquired into myself carefully; but I 
only became the more convinced that my power of perception was become greater 
and more comprehensive. This intellectual clearness was associated with great 
pleasure. I did not sleep, nor did I dream; I was perfectly sober; and my health 
was perfect. I had occasionally had ecstasies, but these had nothing in common 
with this condition of the stomach, in which it thought and felt, and almost 
excluded all cooperation of the head. In the meantime my friends were troubled 
with the fear that I might go mad. But my faith to God and my submission to His 
will, soon dissipated this fear. This state continued for two hours, after which 
I had some dizziness. I afterwards frequently tasted of the A---, but I never 
again could reproduce these same sensations."
