Tacamahaca, a Gummy Resinous substance, obtained from the Carolina Poplar. The best sort is collected from the fruit of the tree, in gourd-shells : it is somewhat soft and unctuous, of a pale-green, or yellowish colour, and a fragrant odour, resembling that of ambergrease, or lavender. The drag commonly met with, in the shops, consists of variegated semi-transparent grains, procured from the sap exuding through incisions made in the poplar; and which are greatly inferior to the genuine species. Tacamahaca is chiefly employed externally, for discussing tumors, promoting their maturation, and mitigating pains in the limbs ; though the finer sort may be advantageously used for the same purposes, as other balsamics.
