Saradomin brew

Saradomin brew is made by mixing toadflax and a crushed bird's nest in a vial of water, giving 180 Herblore experience. It requires level 81 Herblore. It is slightly lighter in colour than a normal strength potion.

Saradomin brew temporarily raises your Hitpoints by 15% (it is one of few ways to raise your Hitpoints above the normal maximum. This effect does not stack with Rocktail) and your Defence by 25% (better than a super defence potion if your Defence level is higher than 50). However, it also temporarily lowers your Strength, Attack, Magic and Ranged by 10%. A 4-dose Saradomin Brew can heal 64 hp (16hp*4doses) in total.

The brew heals the highest non-stackable Hitpoints per inventory spot (the Unicorn Stallion's healing aura scroll and purple sweets can be stacked for approximately 4.2 billion hitpoints), and so, is often used in conjunction with Super restore potions in places such as in the TzHaar Fight Cave while attempting to obtain a Fire cape, high-levelled Bounty Hunting, during Barrows runs (to decrease the number of bank trips required), and even in Nomad's Requiem to defeat Nomad.

Production costs
The table is based on buying the ingredients (vial of water, toadflax, and crushed birds nest) from the Grand Exchange and selling the resulting 3 dose potion there.

Trivia

 * There is no Barbarian version of this potion, presumably because the brew already heals hitpoints.
 * When it is ingested the chatbox message says, "You drink some of the foul liquid", unlike other potions message - "You drink some of your (whatever the potion's name is). You have (1-3) doses left/You have finished your potion."
 * It is strange that it says you drink some of the foul liquid when it is a Saradomin brew, as a potion from a divine and celestial god might be expected to be delicious. However it would not be suprising considering a crushed Birds nest is one of the ingredients for the Potion.
