NOM. VULG.—Palo Maria, Sp.-Fil.; Bitanhol, Tamawian, Dankalan, Dinkalin, Tag.; Dankalan Bitaog, Vis., Pam., Bik.
USES.—From the seeds of the fruit there exudes a yellowish-green oil, bitter and aromatic. It is used in some districts for illuminating purposes. Its density is 0.942 and its point of solidification 5° above zero. In India it is used by inunction in rheumatism and in the Philippines locally over the stomach in indigestion and colic. The bark of the tree when incised exudes a green resin of a very agreeable odor, which is used as an application to wounds and old sores. In India it is used in the same way. This resin is fusible and dissolves completely in alcohol. It has been mistaken for the tacamahaca of India, which, however, is a product of the C. calaba, L. Mixed with equal parts of pitch and wax it is applied to the chest as a plaster in bronchitis. A decoction of the leaves is used for purulent ophthalmia in some parts of India and Mauritius. The pounded bark is applied locally in orchitis and epididymitis. We have had occasion to use a mixture of equal parts of the resin with white vaseline spread on linen and applied between the shoulder blades; in the persistent cough of senile bronchitis the relief was marked.
