Gold, Frankincense and Myrrh

I know what Gold is, a precious metal but I had to look up Frankincense and Myrrh were. According to http://www.ncbi.nlm.nih.gov :

Frankincense and myrrh are two olive plants from different species and genera. Frankincense is a hard, gelatinous resin exuded from the trunk incisions of the frankincense tree, Boswellia carterii Birdw. or other species in the genus Boswellia of the family Burseraceae, mainly from Somalia, Ethiopia, and India
Myrrh is an oily, gelatinous substance exuded from the bark of Commiphora myrrha Engl. or various other species of Commiphora, and can be classified as natural myrrh or colloid myrrh. Myrrh exists mainly in tropical and subtropical areas, such as Somalia, Ethiopia, and the southern Arabian Peninsula
