When consumed, this magical liquid will cure any form of normal
or magical insanity, and will also restore a feebleminded character to
health. If a psionic character who was attacked while defenseless
later drinks this potion, it will cure any psychic damage he suffered
except for death, idiocy, the permanent loss of an attack or defense
mode, or a robot state. This potion will also enable a psionic character
to recover psionic strength points at twice the normal rate for two
hours after the potion is consumed.

Potion notions

Dear Dragon, 
I have a question about the Potion of Mind 
Restoration (Treasure Trove, issue #91).  Does it 
cure the effects caused by potions and magic 
items that affect the mind?  Also I would like to 
know if it cures fear spells.

As described by its author, Mike Persinger, the
potion seems to work against "intellectual damage
" to the mind, as opposed to "emotional
damage." It will cure any form of insanity, a
feebleminded condition, and all but the most
extreme forms of "intellectual damage" that a
defenseless psionic might suffer. It is not good
against, for instance, charm or fear magic, even
though the mind is technically affected by such
forces. The conditions that the potion works
against cause physiological changes; forces such 
as charm spells or other will-force spells cause 
psychological changes, which the potion can't do 
anything about.  To name a few others, the potion 
also won't work against a potion of delusion, to 
offset the effects of a rod of beguiling, or to 
counteract a helm of opposite alignment.
