Use the Curative Animal Salve on 10 Sickly Gazelles that are located throughout the northern part of the Barrens; doing so should cure them. Sickly Gazelles have been reported north of the east-west road that runs through the Crossroads.
I was able to make enough salve for ten doses of curing, <name>. While I work with local authorities to try and make some more salve, I'd like for you to help us get a head start. All around the northern Barrens are sickly gazelles; use the salve on them and cure their malaise.
Dendrite Starblaze in Moonglade will want to talk to you when you're done, I'm sure. Please extend our thanks to the Cenarion Circle there... and let me say thanks to you directly for the help you've given!
