What to know
- Raw gentian reduces health and should never be consumed directly.
- Cooking gentian always requires clear water and a tent.
- Gentian infusion provides long-lasting focus and survival benefits.
- Proper preparation makes gentian ideal for difficult climbs.
In Cairn, not every plant you find is immediately safe to use. Gentian is a perfect example of Cairn’s survival design philosophy: powerful resources often come with a downside unless prepared correctly. While raw gentian harms you, cooking it transforms the plant into gentian infusion, a valuable drink that significantly improves your climbing performance.
Understanding gentian and why preparation matters
Gentian is a bitter medicinal root found during exploration, and the game is very explicit about its danger. When viewed in your inventory, raw gentian reduces health, signaling that it is not meant to be consumed as-is. This design encourages you to engage with Cairn’s cooking system rather than treating food as simple healing items.

Once processed, however, gentian becomes one of the most efficient focus-enhancing consumables available in the early and mid-game. Focus directly affects your ability to manage stamina, timing, and precision during climbs, making gentian infusion especially valuable before complex vertical sections.

Where and when to cook gentian
Cooking in Cairn is always done at your tent, reinforcing the idea that preparation happens during rest, not in the middle of a climb. If you have gentian in your inventory but no tent access, you will not be able to process it.

Before attempting to cook gentian, you must also have clear water. This is a mandatory ingredient. Without it, the cooking option will appear but the process cannot start.
How to cook gentian and make gentian infusion
To begin, enter your tent and select the Cook option. This opens the cooking interface where ingredients are placed manually.
Place the gentian root into the cooker, then add clear water. Both ingredients must be present, or the cooking prompt will remain inactive. Once everything is set, hold down the Square button (or the equivalent input on PC) to begin cooking.

After a short process, the raw root is converted into gentian infusion. At this point, you can either consume it immediately or store it for later, depending on your current condition and upcoming challenges.

Gentian infusion effects and benefits
Gentian infusion lasts for 24 in-game minutes, making it a long-duration consumable compared to basic food or water. Its primary benefit is improved focus, which indirectly enhances stamina management, reduces mistakes, and helps maintain control during extended climbs.
In addition to focus, gentian infusion also provides balanced survival recovery, making it suitable for use before difficult routes where both precision and endurance are tested.

Clear water is non-negotiable
It’s important to stress that gentian cannot be cooked without clear water. Even if you have multiple gentian roots, the cooking process will not start unless water is added. This makes water management just as important as herb collection.

If you find yourself unable to cook gentian, it usually means you are missing clear water, not that the recipe is locked or bugged.
When you should use gentian infusion
Gentian is a textbook example of Cairn’s survival depth. On its own, it’s dangerous and punishing. Cooked properly, it becomes one of the most reliable focus-enhancing consumables in the game. By always pairing gentian with clear water and preparing it at your tent, you turn a risky herb into a powerful climbing aid.
Gentian infusion is best used proactively, not as a panic heal. Drinking it before a demanding climb gives you time to fully benefit from the focus boost, rather than wasting its duration while resting or walking.
Because raw gentian is harmful, it’s generally better to store gentian roots until you are ready to cook, instead of experimenting with them directly.
Treat gentian infusion as planned preparation for hard routes, and it will consistently reward you with smoother, safer ascents.
