The latex then seeps out from the severed vessels, travels down along the cut until it reaches the spout. The rubber finally drops into a collection cup that will later be drained of its latex. Tapping is repeated every other day by making a thin shaving just below the previous cut. When the last scar formed by the cuts is about 0.3 meters above the surface, the other side of the tree is tapped in similar form while the first side renews itself (Rubber, Natural, and Synthetics) Rubber has been used since the very old times. Evidence of rubber use goes back to 2,000,000 years or more. In that time period the substance was naturally derived from Hevea Tree. People would use it to make balls, waterproof handmade buckets, pails and more.

Above 200 species of plant produce a viscous, milky sap—called latex —that contains natural rubber, but only two of these species have become commercially important. The Hevea brasiliensis tree provides above 99 percent of the globes natural rubber supply. Originating in Brazil, the Hevea tree is now cultivated in various tropical countries, including Malaysia, Indonesia, Thailand, and parts of India and China (Rubber, Natural, and
