Resident Evil 4, much like the rest of the franchise, emphasizes the use of herbs to heal your characters. Yellow Herbs, in particular, tend to be very important, as they're the only way for you to increase your maximum HP. Here's our Resident Evil 4 Yellow Herbs guide to help you find all the possible health upgrades in the campaign.

Resident Evil 4 Yellow Herbs guide

The Resident Evil 4 Yellow Herbs can't be used on their own. Instead, you'll have to mix them with a concoction, preferably one that already has a Green Herb and Red Herb mixed in. This is because a Green and Red Herb combination will heal you to almost full HP and, when a Yellow Herb is added, you'll also be granted its permanent max HP boost segment.

Likewise, you'll want to pay attention to the Merchant's Trade panel, since he also sells a Yellow Herb in exchange for 3x Spinels (a currency obtained by completing requests). In any case, we've divided our Resident Evil 4 Yellow Herbs guide into several sections depending on the main zones and areas.
