Over time, the Oro Verde ® mining community has identified three plants that work in the opposite way to mercury and cyanide. The local names of the plants are Peine Mono, Escoba Babosa and Malva. Peine Mono (Apeiba) is a tree, while Malva (Malachra Rudis) and Escoba Babosa (Sida Glutinosa) are weedy herbs. The clue is in the name, as the plants are glutinous and the juice from the plants binds the soil, thus separating and extracting the gold from the gravel.
