Morag levitates a bag of bug bite cure to Umwak.

"We Duloks have been troubled by insect bites lately, and we were wondering if you could spare…"
Umwak begs Morag for a potion of her bug bite cure[src]

Bug Bite Cure was a potion prepared by the Tulgah witch Morag that kept irritating bugs of the forest moon of Endor away from sentient creatures such as the Duloks. The Dulok Shaman Umwak was forced to grovel to Morag and promise favors in return for the substance. Morag would reluctantly part with the bug bite cure only after the Duloks would agree to do Morag favors in return.
