"Description -- An oleoresin obtained from a South American species of Copaiba, by an incision in the trunk. It was first noticed in England in 1625, in a work published by Purchas. There are many species in South America, all yielding Copaiba- a single tree is said to yield about 40 litres. The first yield is clear, colourless and very thin, but in contact with the air its consistency soon becomes thicker and yellower. It is most largely collected from Para and Maranhao in Brazil, and is brought to this country in small casks and barrels; large quantities also come from Maracaibo in Venezuela, and it is also exported from Angostura, Cayenne, Rio Janeiro and some of the West Indian Islands. The variety that comes from Venezuela is more viscid and darker in colour." -- Botanical.com

            *** Copaiba was traditionally used as an antiseptic for sore throats, which probably explains why it's added to cigarettes: It fools the body into thinking smoking isn't hurting. ***
