Warrior Cats Guide to Herbs: What Every Herb Does

There is no complete herb list on the official Warrior Cats website, and that surprises people who go looking for one. The publisher does explain the job: a medicine cat must learn the appearance and scent of every known herb, when it flowers, when it produces seeds, where it grows, and what it treats. The specific uses live in the novels, and this guide collects the ones that appear most often, with the treatment each plant is associated with in the books.

• Catmint is the series' go-to for greencough and whitecough
• Cobwebs stop bleeding and hold poultices in place
• Poppy seeds dull pain and help a cat sleep
• Yarrow is used to make a cat vomit poison
• No official herb table exists - the books are the source, not a publisher database
• Doses are never given in numbers - medicine cats work by judgement, and so should you

Official source: the role, the training and the herb store are described in The role of a medicine cat on warriorcats.com. The plant uses below come from the novels published by HarperCollins, which you can browse in the official books index. The game's own feature set is listed on Steam.

What a Medicine Cat Actually Has to Learn

The official article on the medicine cat role is unusually specific about training. An apprentice has to memorise the look and smell of every known herb, the season it flowers in, when it seeds, where it can be found, and what it is used for. That is the baseline before treatment starts. After that comes the store: keeping it stocked, sorting it, and throwing out anything too old or withered to be useful.

The same article describes medicine cats growing their own supplies. Jayfeather keeps a herb garden beside an abandoned Twoleg den, which is a practical detail rather than a decorative one: a medicine cat who runs out of catmint in leaf-bare has a problem no amount of skill solves. Cobwebs are collected and stored for stopping bleeding. Dislocated joints can be reset. Minor treatments are simple enough that Firestar had all of ThunderClan taught the basics, and Brightheart learned more than that.

That context matters for reading the table below. Herbs in these books are not potions with fixed effects. They are plants a cat has to find, identify, preserve and apply, often in weather that makes all four difficult.

The Core Herb List

The table collects the herbs that recur across the arcs. The right-hand column describes how the books use them, not a real-world medical claim.

Two entries deserve a caution. Mouse bile is a treatment applied to a tick, not something a cat swallows, and the books treat it as unpleasant for everyone involved. Yarrow is used to make a cat sick when something poisonous has been eaten, which means it is dangerous to use casually.

Poisons and the Plants to Avoid

Deathberries are the series' shorthand for the worst outcome. They are yew berries, they are bright red, and they kill a cat who eats them unless a medicine cat intervenes almost immediately. Yarrow to induce vomiting is the standard response, and even then the books do not guarantee survival.

The other dangerous plants show up less consistently across arcs, which is exactly why fan herb lists disagree with each other. A plant described as dangerous in one book may be used medicinally in another, and the series has been running long enough that some details have drifted. If you are writing a fan treatment scene, the safe approach is to use the well-established herbs in the table and avoid inventing new poisons.

How Treatment Scenes Are Written

Every medicine cat scene follows the same rough shape: diagnose, choose a herb, prepare it, apply it, watch the patient. The diagnosis is usually the hard part. Greencough and whitecough look similar but carry different urgency, and a medicine cat who treats whitecough as harmless can lose a kit to it.

Preparation is where the books get tactile. Leaves are chewed into a poultice. Roots are chewed and spat onto a wound. Cobwebs are pressed flat. Seeds are licked from a leaf. Doses are never given in numbers, because the books are written for children and because a medicine cat is supposed to be judging by the patient rather than measuring. That absence of numbers is the main reason fan herb guides disagree: there is no canonical dose to copy.

The herb store is the other recurring scene. A medicine cat inventories it before leaf-bare, sends apprentices to collect, and argues with leaders about which cats are well enough to fight. The store is a resource, and running out of it is a plot device.

The Rules Around Medicine Cats

Medicine cats sit outside the warrior code rather than inside it. They cross Clan borders freely because every Clan needs treatment, they are barred from taking mates or having kits, and they are the cats who interpret signs from StarClan. None of that is a numbered rule in the official code, which is worth knowing if you are writing about the code itself. Our warrior code list covers the 15 rules that do exist.

Their position in the Clan hierarchy is unusual too. A medicine cat is not a warrior, does not lead patrols, and does not fight except in defence, but their opinion carries weight with the leader. Our Clan ranks and roles guide places them alongside leaders, deputies, warriors and apprentices.

Herbs and the Game

Clans of the Forest is an action RPG built around a created cat and a Clan campaign, and its advertised feature set does not include a herb-gathering or medicine system. If you came here from the game looking for a crafting tree, there isn't one to match this table. What the game does use is the setting: the Clans, the territories and a roster of book cats. Our game overview covers what is actually in the release, and our beginner's guide covers the first few hours.

For readers, the herbs are a good test of how carefully a scene is written. A medicine cat who reaches for catmint when a cat is bleeding is a mistake the books do not make, and noticing those details is half the fun of the medicine cat chapters.

FAQ

What herb cures greencough in Warrior Cats? Catmint is the standard treatment for greencough and whitecough. It is the herb medicine cats worry about running out of before leaf-bare.

What are deathberries? Bright red yew berries that are poisonous to cats. Eating them is usually fatal without immediate treatment.

Does the official site have a herb list? No. The official site explains what a medicine cat has to learn, but the specific plant uses are described in the novels rather than published as a table.

Can medicine cats have kits? No. The role forbids taking a mate or having kits, and the books treat breaking that rule as a serious conflict.
