Character statistics
From Witcher Wiki
Character statistics are the most important way to gauge the overall health of our hero. Whether Geralt lives or dies is governed by his Vitality, but Endurance and Toxicity play their parts.
[edit] Endurance 
Geralt's endurance, indicated by the yellow bar, drops each time he uses a sign. He cannot cast signs when his endurance is too low. In fistfights, blocking also siphons Geralt's endurance; reaching zero, Geralt cannot block.
Endurance is restored over time. Use potions to help with its regeneration or
- Tawny Owl accelerates its regeneration
- Maribor Forest significantly increases its maximum level
- Non-alcoholic beverages give 9 minutes of slightly accelerated endurance regeneration each
[edit] Toxicity 
Toxicity, indicated by the green bar, increases with each potion consumed. Excessive toxicity adversely affects Geralt's abilities and may even lead to his demise. When toxicity is reaching a dangerous level, "red sparkles" begin to appear in the field of view, like Geralt is beginning to hallucinate. This is generally a very good indication that it's time to detox.
- Meditation detoxifies completely, usually an hour is sufficient, except for drunkenness, which can take several hours to "cure"
- White Honey
- Ritual of Purification
[edit] Vitality 
Vitality (sometimes referred to as "hit points"}, indicated by the red bar, drops as damage is incurred. If the red bar reaches zero, Geralt dies. A grey screen and (very) audible heart beats warn you of dangerously low vitality. Recover by meditating or drinking potions like the Swallow.
- Swallow accelerates its regeneration
- White Raffard's Decoction gives an instant boost, but is highly toxic
- Food provides 9 minutes of vitality regeneration each time an item is consumed
