Messages

Message	Reason
"Yecch! This stuff tastes like poison."	You always receive this message.
"But in fact it was mildly stale [fruit; default is slime mold] juice.)"	The potion was blessed.
"(But in fact it was biologically contaminated [fruit; default is slime mold] juice.)"	The potion was not blessed, but you have poison resistance, so you only lose one point from one of your statistics.
"Fortunately, you have been immunized."	You are a Healer, so you suffer no ill-effects (hallucination is still cured).
"You are shocked back to your senses!"	You were hallucinating.

Identification

Potions of sickness can be identified by #dipping a unicorn horn into them, which turns them into fruit juice. Zapping with a wand/spell of cancellation also converts to fruit juice.

However, if neither of those are available, dipping a missile weapon into a potion of sickness should form a coating on it.

Strategy

You can #dip darts, arrows, shurikens and crossbow bolts into potion of sickness to coat the projectile weapon in poison. Unfortunately, in vanilla NetHack, this does not work on daggers, although it does in SLASH'EM.
