Philter of Love

From Dungeon Master's Guide, page 184. Found on Magic Item Table B.

Description
''Potion, uncommon. 0.5 lbs.''

The next time you see a creature within 10 minutes after drinking this philter, you become charmed by that creature for 1 hour. If the creature is of a species and gender you are normally attracted to, you regard it as your true love while you are charmed. This potion's rose-hued, effervescent liquid contains one easy-to-miss bubble shaped like a heart.
