Ingredients:
water (500mL)
jobberknoll feathers (2 barbs)
leeches (juiced; 1-2)

Instructions:
Bring water to a boil
Separate the barbs from the shafts of 2 jobberknoll feathers
Place barbs in boiling water and stir 12 times clockwise and 7 times counter-clockwise
Boil for 30 minutes
Add leech juice by squeezing one leech into the cauldron and stir in an unpredictable fashion
Keep stirring until potion should thickens (within 5 minutes)
If potion does not thicken after 10 minutes of stirring, add another leech and continue to stir unpredictably until thickened
If potion has still not thickened after an additional 10 minutes, start another brew

Notes:
This particular brew is a mild variation of the Confounding Concoction but, should be effective for several hours if an antidote is not administered.
It can be very difficult to discern whether one has ingested confounding concoction. Depending upon how strongly it is brewed and the person it is administered to, a person may only show a tendency to forget things and the effects will wear off in a few hours. Or, with a stronger version, a person can become completely confused and disoriented and could possibly suffer from amnesia.
There are no discerning smells or tastes so this potion can be easily disguised and given to the unwary.
One side effect of this potion is an increased thirst.
People under the effects of the confounding concoction can be very unpredictable.
