Purple herb (gaiden)
The Purple Herb (紫の草 Murasaki no kusa?) is a health item available only in the non-canon Resident Evil Gaiden and the Biohazard 0 TRIAL EDITION. In Gaiden, it cures both physical and poison damage.

It has been speculated the herb would have healed Bleeding status, suggesting this would have been a mechanic eventually cut from Resident Evil 0, as many B.O.W.s. native to RE0 cause this condition in both Outbreak games.
