The prayer book is a reward from the The Great Brain Robbery quest. By right clicking on it while wearing the Holy symbol, the player can use Prayer to heal poison at the cost of some prayer points (see last paragraph). Sometimes the poison will only be partially healed if you run out of prayer points.
The Prayer book should ideally be used after combat because the monster a player is fighting could poison again, causing the player to drain their prayer points further (to heal poison), and wasting time in which the monster could have been attacked. An alternative to using the prayer book is to use a form of anti-poison potion, such as Super anti-poison potion or Antidote++.
If lost, the Prayer book can be reclaimed in the Edgeville Monastery (southwestern bookshelf) where it was originally found or in a player-owned house bookcase. In the bookcase it is called "Prayer of Deliverance from Poisons." Although this book has a 'destroy' option, it is possible to get more than one copy. This can be done by keeping the book in your bank while you obtain a new one from your player-owned house bookcase.
A good place to use the Prayer book is on Ape Atoll in the Gorilla temple, where there is a prayer altar surrounded by level 167 Gorillas and level 1 poisonous spiders. Using the Prayer Book to counter the poison, fighting the Gorillas after a while will allow a player to fight the creatures without them automatically attacking. During the fight, protect from melee prayer is used sometimes in conjunction with chivalry or piety prayers.
To calculate how many prayer points it will cost to heal, subtract 2 from the poison damage. For example, if someone is poisoned for 8 damage each time, it will take 6 prayer points to heal them. If a player only has a portion of the required prayer points needed to cure poison, they will only be partially healed of poison and the remaining few points will be drained.
