DRUGS asi 



produced by this drug as in the nature of agreeable dreams 

 followed by a sort of voluptuous stupor. 



COPAIBA 



Copaiba balsam is obtained from the tree Copaifera langs- 

 dorfii, native of Brazil, attaining a height of 50 to 60 feet with 

 pinnate, leathery leaves and apetalous flowers. Copaiba is an 

 oleoresin which collects in cavities in the trunk of the tree. 

 It is also collected by artificial tapping. For this purpose 

 grooves or cuts in other shapes are made in the trunk in the 

 summer, and the transparent, colorless liquid is allowed to 

 exude and dry into the resin. As much as 10 or 12 pounds of 

 this resin may be collected from a single tapping. 



PERU BALSAM 



This balsam is obtained from a leguminous tree {Myroxylon 

 pereirce), native of South America, attaining a height of 50 

 feet, with alternate, pinnate leaves, white flowers, and one- 

 seeded pods. The balsam naturally collects in the cavities in 

 the bark of young twigs, where it is obtained by bark incisions 

 or exudes from bark wounds in the trunk. A very fragrant 

 form of the balsam is also obtained from the fruit. The tree 

 from which the Peru balsam is obtained sometimes reaches 

 a diameter of 2 feet, the bark is thick, the sap wood almost 

 pure white, and the bark wood reddish-brown. The wood is 

 extremely hard and has been used for various purposes as 

 timber. 



TOLU BALSAM 



The tolu balsam tree {M. toltdferum) is taller than the tree 

 from which Peru balsam is obtained, higher branching, but 

 otherwise like the Peru balsam tree. Tolu balsam in the crude 

 form contains 75 per cent, resin, which also yields the oil 

 toluol used in dyes and as a volatile antiseptic.
