Herbal tincture

Herbal tincture is a quest item used in the One Small Favour quest. It is obtained by talking to the Apothecary in Varrock. The player is asked to make an airtight pot to replace the one the Apothecary drops in return for the breathing salts that are needed along with the tincture. It must then be taken to Horvik to complete the next step in the quest.
