Hevea brasiliensis
"Ficus elastica" yields a milky white latex, a chemical compound separate from its sap and carried and stored in different cells. This latex was formerly used to make rubber, but it should not be confused with the Pará rubber tree ("Hevea brasiliensis"), the main commercial source of latex for rubber making. Just as with "Hevea brasiliensis", the latex of "Ficus elastica" is an irritant to the eyes and skin and is toxic if taken internally.
