In The Elder Scrolls IV: Oblivion, curing disease is straightforward and can be done in several ways:

• Casting a Cure Disease spell : This Restoration school spell instantly removes all diseases affecting your character. You can purchase this spell from priests at Altars of the Nine or create potions with the same effect

• Drinking a Cure Disease potion : Potions with the Cure Disease effect will also instantly cure all diseases. You can buy these potions or craft them using alchemy ingredients like Clannfear Claws, Mandrake Root, or Root Pulp

• Eating specific food or ingredients : Consuming raw ingredients such as Mandrake Root or Shepherd's Pie acts like a Cure Disease effect and will fully heal any diseases

• Praying at a Chapel : Visiting any chapel in major cities and praying at the altar will cure diseases for free without using Magicka. This is an easy and efficient method if you can reach a chapel quickly

A single Cure Disease effect cures all diseases at once, except for Vampirism itself. The disease Porphyric Hemophilia, which causes Vampirism, can be cured only within the first three days after infection using Cure Disease. After that, curing Vampirism requires more complex measures

. In summary, to cure disease in Oblivion, use a Cure Disease spell or potion, eat certain ingredients, or pray at a chapel. For Vampirism, act quickly within three days to cure the initial disease before it progresses.
