TACAMAHACA, in pharmacy, a solid resin, improperly called a gum, in the shops: it is of a fragrant and peculiar smell, and is of two kinds; the one called the shell-tacamahaca, which is the finest; the other, which is an inferior kind, being termed rough-tacamahaca, or tacamahaca in grains.
Some greatly commend tacamahaca in disorders of the breast and lungs; but, at present it is very rarely used internally. Externally, however, it is in repute for softening tumours, and mitigating pain and aches.
