Most of the games up to Resident Evil 4 has them function similarly with games afterwards having reworking them each time. Herbs typically come in different colors and individual and mixed herbs usually have similar properties across different games. This led to them being used and cultivated all around the world. Herbs became popular in Raccoon City and were being used in various products and home recipes such as in Herb Pie and Herb Cream.īy 2003, these herbs were being widely used in the medical field and were recommended by botanists to be kept around to help protect individuals from the rising threat of bioterrorism. An Asian medicine doctor specifically made the discovery that mixing blue and red herbs creates an effect that 'strengthen one's constitution'. īy 1998, botanists had researched and documented the fact that the red herbs could in fact be mixed with other herbs in order to magnify their effects. The Umbrella Corporation created other species of the herbs that could grow on Rockfort Island and at the Antarctic Base by breeding the ones from Raccoon City. The blue herb neutralizes natural toxins, while the red herb has no effect when used on its own.

The green herb recovers physical strength and heals fatigue, helping to strengthen the natural healing process so that wounds heal faster while also having an active immune function that helps fight viral infection. There are many species of herbs which are native to the Arklay Mountains, the region of the American midwest where Raccoon City was located, and each kind of herb has a distinct color and medicinal quality.
