what is kitalasua?

jambo!

i’m a westerner traveling in arusha and stumbled upon an herb in the spice market the vendor named kitalasua. he had me snort a bit saying it was good for flu and headache. it opened up my sinuses and made my nose run.

i’ve tried researching an english name for the stuff and have come up empty. can anyone help?

asanti sana!
