    • n tacamahac A gum-resin, the product of several trees, originally that of one or more South American species. The most important tacamahac is derived from Calophyllum Inophyllum, of the East Indies, Polynesia, etc. (see tamanu), of which the C. Tacamahaca of Madagascar and the isle of Bourbon is a variety. The resin is of a greenish-yellow color, liquid at first, but hardening into a brittle aromatic mass soluble in alcohol and ether. It exudes spontaneously or through incisions from the bark and roots. A similar gum is afforded by C. Calaba in the West Indies. The South American tacamahac is the product of Bursera (Elaphrium) tomentosa and B. excelsa, of Protium(Icica) heptaphyllum, and perhaps of some other trees. The buds of Populus balsamifera (see def. 2) are varnished with a resin which may be included under this name, occasionally used in the place of turpentine and other balsams. Tacamahac is sometimes used for incense, was formerly an esteemed internal remedy, and may still be somewhat used in plasters, but is very little in the market. In this sense often tacamahaca.
    • n tacamahac The balsam poplar, Populus balsamifera, found from the northern borders of the United States to Alaska: in the variety candicans known as balm of Gilead, and common in cultivation. It is a large broad-leaved poplar with fragrant buds.
