Medicine

A medicine cat's main job is to heal their fellow Clanmates from their wounds. They have many ways of doing so, mostly through herbs and berries throughout the medicine cat of their Clan's store.

Burnet
A travelling herb first used in The Fourth Apprentice. Little is known about it.

Daisy Leaf
Jayfeather brought a daisy leaf to Mousefur to smell, thinking it might be the mystery herb that Leafpool mixed in with the tansy.

Lamb's Ear
This herb was discovered first by the Tribe cats, and then when the Clans were resting in their territory, Stoneteller told Leafpaw about this herb.

Mouse Bile

 * Extracted from the mouse. The only remedy for ticks, mouse bile is foul smelling, and is stored in moss. When dabbed on a tick, the tick falls off. Smell can be masked by wild garlic, or by washing paws in running water. If accidentally swallowed, can leave a horrible taste in mouth for days. Medicine cats always have to remember to wash their paws in a body of water, such as a creek or stream, after using mouse bile.

Ragwort Leaves
It was used in The Fourth Apprentice when Jayfeather gave it to the elders to help them during the drought.

Ragweed
Ragweed was first discovered by the Tribe cats, later being told to Leafpool by Stoneteller when the Clans were resting in their territory.

Tormentil
It's used in the Tribe of Rushing Water, and is mentioned by Stoneteller to Jaypaw when he is taking care of Gray.

Traveling Herbs

 * Traveling Herbs consists of sorrel, daisy, chamomile and burnet.

Watermint
In Fading Echoes, it was also used to smooth Leopardstar's pelt and hide the scent of death from it.

Wintergreen
Stoneteller mentioned to Jaypaw while treating Gray's wound, wondering if the Clans used it.

Yarrow
Yarrow was used on Sorrelkit by Cinderpelt when Darkstripe fed her deathberries.

Nightshade
Mentioned in Forest of Secrets when Fireheart and Cinderpaw are with Cloudkit. Cloudkit almost eats some deathberries, but is quickly stopped by Cinderpaw. When Cloudkit runs off and calls them to see what he found, she jokes in response that "Maybe it's deadly nightshade this time".

Deathberries/Yew berries/Night Seeds

 * Main Article: Deathberries

Holly Berries
Holly berries, while not as dangerous as deathberries, but are still a danger to kits. They make an appearance in Twilight, after Leafpool talks to Crowfeather, Sorreltail finds her hiding in a holly bush. Leafpool says she is looking for berries and Sorreltail asks, "Aren't they poisonous?".

Foxglove Seeds
They are often mistaken for poppy seeds because they look extremely similar. They are known to be a dangerous medicine. They are mentioned when Yellowfang scolds Cinderpelt and says, "You're a dangerous medicine cat! You could kill a cat by confusing foxglove seeds and poppy seeds!".
