Attack the giant wasp in the path while you have the element of surprise!
Drink the potion quickly. You must be very close to finding the hive and you'll need its protection.
Wait a bit where you are, motionless. You don't want to drink the potion too soon or you may not find the hive before its effect wears off. Let the wasp go on its way and then keep walking down the path.
Don't drink the potion just yet. Leave the path and cautiously follow the scent of the Tree of Sorrow blossoms.
Some other creative option? (Please comment.)
