Herbs are the primary healing items in the Resident Evil series. Every game to date has had herbs.
In Resident Evil: Revelations, herbs can be instantly used just by pressing the A button.
In Resident Evil: Revelations 2, players need to hold corresponding button for a while for an herb to use, it is used in form of a spray.
Types of herbs
There are three main types of herbs: green, red and blue. Resident Evil 4 throws out the blue herb and features a new, yellow herb. Resident Evil 5 contains only red and green herbs, and only 2 herbs may be combined at once.
The base herb. Heals a small amount of health. For most of the games, it will restore health by one rating (yellow caution to Fine, etc.). It can be combined with any of the other herbs, though only three herbs of any type can be combined at once. When the user is in danger or critical health level, a single green herb by itself will be much more effective than it would be otherwise sending the user back to Yellow Caution. In Resident Evil: Revelations, though, it fully restores vitality, even if you are really low on health.
Blue herbs are used to cure poison. As Resident Evil 4 does not have poison, they are not featured in that game. Note that some creatures, most notably the Yawn, have poison that cannot be cured by a Blue Herb. These poisons require a special serum. Resident Evil 5 and 6 also don't feature Blue Herbs due to the lack of venomous enemies.
Red herbs have no effect on their own. (Except in the Outbreak games, as they stop infection temporarily, and the Gaiden game, where they heal heavy damage.) They must be mixed with green herbs to triple the healing effect. In later games, as health is measured in a bar instead of ratings, they simply restore the target's health completely (in RE5 they completely heal both the user and the person being healed).
Resident Evil 4 features a yellow herb to increase the player's (or their ally's) maximum health. They are only usable when combined with a green herb or both a green herb and red herb.
Resident Evil: Gaiden was the only game to feature the purple herb. It has the ability to heal both poison and heal 25% of the users health.
In Resident Evil Zero a Pink Herb was to be featured but was removed early in development, It's purpose is unknown.
Herbs can be combined in order to increase variety of effect, as well as saving inventory slot. Only 3 herbs can be combined in one slot. In terms of appearance, mixed herbs are grint to powder, and is contained in a piece of paper.

- In games 1-3, as well as 0 and Revelations, herbs were described as being native to Raccoon City and the surrounding mountains, yet they still appear at Ivy University, at Rockfort Island, in the Antarctic Base, Spain, Kijuju, Edonia, and even China. This is because these types of healing herbs were grown around the globe by Umbrella. That's the reason they were in Code: Veronica, Survivor Series, Resident Evil 4, Resident Evil 5 and Resident Evil 6.
- Though nearly all of playable character know how to mix herbs, Billy Coen is the only character who does not know how to mix herbs. This possibly because he is not a native of Raccoon, and at the time of Resident Evil 0, the knowledge about herbs are not known well worldwide.
