|Examine||An unfinished herb tea made up of water, guam and marrentill.|
It was made during One Small Favour to prepare a cup of Guthix rest. Making Guthix rest gives a total of 59.5 Herblore experience. If more than the required number of herbs were added, ruined herb tea would have been obtained.
After Guthix rest was updated on 20 May 2013 and no more herb tea mixes could be made, any existing tea mixes before the update remained in the game and were still tradeable, making it a discontinued tradeable item. However, this went unnoticed by the general public as well as by Jagex for over a year and a half, until March 2015. Shortly after on 9 March 2015, the unfinished mixes were made untradeable as they were never intended to become a discontinued rare item.
