'''Serum 207''' is a temporary cure to the [[afflicted]] villagers of [[Mort'ton]], who are otherwise incoherent. A player who has read the [[Diary of Herbi Flax]] during the quest [[Shades of Mort'ton]], and has a [[Herblore]] level of at least 15, may produce it by adding [[Clean tarromin|Tarromin]] and [[Ashes]] to a [[vial of water]], giving 50 herblore [[experience]].

Originally, players may have found it economically easier to use an [[ash potion (unf)]], but with the update on [[17 October]] [[2012]], this item was removed. Players must now use a tarromin potion (unf) with ashes.

The potion may be used on an [[afflicted]] villager, who will temporarily become coherent and reward the player. In addition to [[Shade key]]s and Level 1 [[clue scroll]]s, the possible rewards include all the items required to make the potion, allowing the process to be repeated for an inexpensive, if slow, method of training Herblore. It may also be used on the sacred flame in the [[Temple of Mort'ton]] to produce [[serum 208]] (see [[Shades of Mort'ton (activity)|the Shades of Mort'ton activity]] for more on that process). Serum 208 is required during the quest, and will give greater rewards when used on the afflicted.

Because ashes are cheaper than the other ingredients which may be combined with Tarromin, which is itself a cheaper herb, the potion is a herblore training option with an excellent price-to-experience ratio. However, players planning to produce large quantities of the potion should be aware that they are difficult to dispose of. They were made untradeable after the introduction of the [[Grand Exchange]], and therefore cannot be withdrawn as a [[note]] nor sold to any store. A player unwilling to sacrifice a bank slot for them must either empty or drop them one-by-one; alternately they could die in the [[Wilderness]] with 28 vials of serum over and over again. They do not even count as junk in [[Mobilising Armies]]. This tedious activity can be reduced by having [[Bob Barter]] decant them into 4 dose potions.

If emptying the vials, the quickest method is to empty them per column of vials in inventory. Start at the top of a column, right click on a vial, select the empty option. Selecting the empty option moves the mouse pointer down about one row in the inventory, and a little practice can easily have it end up positioned over the next vial, whereupon the process is repeated. This greatly reduces the amount of time spent moving the mouse.

Another emptying method can be used by players training herblore and using Bob Barter to decant their potions. When at a banker in the Grand Exchange, withdraw 5 vials of Serum 207 along with the potions to be decanted. Run to Bob Barter while emptying two of the vials of serum. Then, while Bob Barter is decanting the potions, empty another vial. (A little practice is needed here to avoid starting too soon, which fails, and too late, which wastes time. When done correctly, Bob Barter's chat head does not even appear to announce the decanting is done; instead, the vial simply empties.) Finally, empty the last two vials when running back to the Grand Exchange banker. This allows 5 vials to be emptied in no more time that it takes to do a decanting run.

====Cost-benefit analysis of curing====
Simply subtract the current production price (seen below) from the current sale price of the reward items to see that players can easily break even by curing, and, given a few favorable results from any received clue scrolls, could even profit greatly (see [[Vestment robes|the God robes sets]]).

In one test run where over 700 (4) dose serum were used, the number of [[tarromin|tarromin herbs]] rewarded was actually more the number used to make the potions, generating a 100%+ profit. On the downside, the endeavor took nearly a week and a half of heavy playing to complete. (note; ALL items were retained. considerable time could be saved by dropping empty vials and undesired items)

Unfortunately, as curing or "using" the potion requires a massive time and energy commitment, especially for players who have made thousands of these potions, and given that the money spent is generally not monumental to begin with, the loss of money is widely held as acceptable. If the player is so inclined, however, the method is viable.

==Production costs==
This table is based on the [[Grand Exchange]] prices of a [[vial of water]], the tarromin, and ashes. It is accurate assuming all three items are bought from the Grand Exchange. Note that the Serum 207 cannot be sold afterwards.

== Trivia ==

Serum 207 used to be tradeable until an update in early 2008 where this ability was removed.
