[[File:Sanfew serum detail.png|left|A detailed view of a vial of Sanfew serum.]]

'''Sanfew serum''' combines the properties of [[Super restore]], [[Antipoison|Anti-poison]], and [[Relicym's balm]] (though, unlike the latter, will provide immunity to disease when drunk) potions. Level 65 [[Herblore]] and completion of [[Zogre Flesh Eaters]] is needed to make this potion. It gives 96 herblore experience for a completed 1-dose Sanfew serum, 128 herblore experience for a completed 2-dose Sanfew serum, 160 herblore experience for a completed 3-dose Sanfew serum, or 192 herblore experience for a completed 4-dose Sanfew serum. 

Sanfew serum is made by adding, in order, [[Unicorn horn dust]], [[clean snake weed]] and [[Nail beast nails]] to an already made Super restore potion. The dosage of the completed Sanfew Serum is the same as the dosage of the Super restore used in the combination. Partially completed Sanfew Serums are called [[Mixture - step 1]] and [[Mixture - step 2]], but are not drinkable in these forms.<center>[[File:Super restore (4).png]]  +  [[File:Unicorn horn dust.png]]  +  [[File:Clean snake weed.png]]  +  [[File:Nail beast nails.png]]  =  [[File:Sanfew serum (4).png]]</center>

Players therefore need to make sure that the unicorn horn dust is highlighted before clicking each of the vials to avoid accidentally drinking any of the Super restore. Since the intermediate potions are not drinkable, the same danger does not exist once the unicorn horn dust has been added.

Partial herblore experience is given for each addition of one of the secondary ingredients in this potion, but varies non-proportionally depending on the dosage of the Super restore used.

A complete Sanfew Serum can be used as a weapon against [[Nail beast]]s, causing significant damage and yielding some [[Herblore]] experience. To use it as a weapon, right-click on the potion and select '''use''', then click on a Nail beast. This should be done if a nail beast is attacking the follower in [[Temple Trekking]].

Players making this potion for experience may find it beneficial to use a Super restore (4) on an empty vial to create two Super restore (2) as the base ingredient for Sanfew Serum. Doing so yields 256 xp from each Super restore (4) instead of 192 xp, although it uses twice as many other ingredients.

Players cannot use the Assist System to make this potion.

== Flask ==
This potion can be made into a [[Sanfew serum flask]] by using at least six doses of it with a [[Potion flask]]. Players do not need a specific level to turn potions into flasks.

==Production costs==
The data in this table is based on the Grand Exchange prices of a [[Super restore|Super restore (3)]] (the primary ingredient) and secondary ingredients. It is accurate assuming all items are bought off of the Grand Exchange and the resulting three-dose potion is sold immediately afterward.

Note: Snake Weed is an untradeable item, so it cannot be bought. Therefore it has no cost.
