Oleo-gum-resin from the sap extracted from the rhizome/root. After the winter has passed the leaves of the plant are cut right down to a tuft. After a week, this is cut off with the top of the rhizome and the milky sap is collected for the next few days. Another slice is taken off the top once the first cut has dried. This process continues for about three months during which about one kilogram of this milky sap will be collected. This matures in pots in the ground into a reddish brown resin.
