Natural latex is a milky juice (thickening in the air) contained in special tissue channels of some plants, usually the Hevea tree, originally growing in the tropical regions of America. After cutting the rubber plant, this juice flows into the prepared bowls. The main plantation species are "ribbed smoked sheet" and "pale latex crepe".
