Amulets that protect against "mal-olhado" tend to be generally resistant, mildly to strongly toxic and dark plants in specific and strategic places of a garden or the entry to a house. Those include "comigo-ninguém-pode" ("against-me-nobody-cans"), "Dieffenbachia" (the dumbcane), "espada-de-são-jorge" ("St. George's sword"), "Sansevieria trifasciata" (the snake plant or mother-in-law's tongue) and "guiné" ("Guinea"), among various other names, "Petiveria alliacea" (the guinea henweed). For those lacking in space or wanting to "sanitize" specific places, they may all be planted together in a single "sete ervas" ("seven herbs") pot, that will also include "arruda" (common rue), "pimenteira" (Capsicum annuum), "manjericão" (basil) and "alecrim" (rosemary). (Though the last four ones should not be used for their common culinary purposes by humans.)
