Zahur

Zahur is a woman in Nardah. She cleans grimy herbs for 200 coins per herb.

Zahur will also decant 4-dose potions into 3-dose potions, for a small fee of 50 coins per inventory converted (regardless of how many potions are in inventory). The player does not have to supply empty vials for the decanting, as Zahur's fee covers this service. Indeed, Zahur will not use a player's vials if a player brings some.

The player should make sure to have room in inventory for the potions generated this way, or Zahur will refuse to decant them. (21 4-dose potions would become 28 3-dose potions, filling inventory entirely, and thus is the maximum that can be decanted in one 'go'.)

Trivia

 * Before the 2007 herbal update, herbs were unidentified herbs, or "unids". Players with the proper Herblore level would be able to identify herbs. Higher level herbs would remain unidentified herbs. Zahur could identify a player's higher level unids for 200 coins each.
 * Zahur's herb-cleaning ability is seldom used, because a player who can use a herb in a potion already has the ability to clean it, for free. If the player can't clean the herb, there is still no reason to pay to have it clean. It can remain in bank until the player has the level to clean it. If the player intends to sell the herb, grimy herbs can be sold on the Grand Exchange as well as clean ones.
 * Bob Barter does the opposite of Zahur and will combine any 3-dose, 2-dose and 1-dose potions in your inventory into vials containing 4 doses.
 * The update in which she was released referred to her several times as "He", when she is actually a female.
 * Although her examine says she sells herbs, she actually cleans them.
 * Seeing as she can clean all herbs, she must easily have 75+ Herblore.
