"Come, and I'll anoint you with the chanmasu herbs. Whether you believe in ritual or not, the scent will discourage your foe."
―Chanya Medaal[src]

Chanmasu was a type of herb that was native to the planet Alderaan and gave off a scent that discouraged Killiks from attacking. The Order of Extermination anointed their members with the herbs during rituals in their efforts to eliminate the Killiks.
