Knowledge does sound useful...

The warning that the knowledge the philtre brings comes at a price makes you hesitant to mess around with this vial. On the other hand, some knowledge could come in handy in deciphering your Uncle's research further, and might help you avoid any mishaps with the other ingredients.

Cautiously you uncork the vial, a sweet smell like crushed berries and apple pie wafting forth from within. Without even realising it you've brought the bottle to your lips, and you suddenly pause. Perhaps drinking it from the bottle isn't the best idea?
