Sanfew serum

Sanfew serum combines the properties of super restore, superantipoison, and Relicym's Balm (though, unlike the latter, will provide immunity to disease when consumed) potions. Level 65 Herblore and completion of Zogre Flesh Eaters is required in order 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.

The duration of the antipoison lasts 6 minutes, the same time a super antipoison does.

Creation
Sanfew serum is made by adding, in order, Unicorn horn dust, clean snake weed and Nail beast nails to an already made 4 dose Super restore potion. Partially completed Sanfew Serums are called Mixture - step 1 and Mixture - step 2, but are not drinkable in these forms.

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.

Herblore experience is given for each addition of one of the secondary ingredients in this potion.
