Flowers, white or pale rose on short pedicels in single axillary racemes are shorter than the leaves.

 The trees on the somali coast grow, without soil, out of polished marble rocks, to which they are attached by a thick oval mass of substances resembling a mixture of lime and mortar. The young trees furnish the most valuable gum, the older yielding merely a clear, glutinous fluid, resembling copal varnish.

 Boswellia Carterii:drawing of whole plant To obtain the Frankincense, a deep, longitudinal incision is made in the trunk of the tree and below it, a narrow strip of bark 5 inches (12.7 cm) in length is peeled off. When the milk-like juice which exudes has hardened by exposure to the air, the incision is deepened. In about three months the resin has attained the required degree of consistency, hardening into yellowish 'tears'. The large, clear globules are scraped off into baskets and the inferior quality that has run down the tree is collected separately. The season for gathering lasts from May till the middle of September, when the first shower of rain puts a close to the gathering for that year.

 As with all essential oils, do not use undiluted. Do not take internally unless working with a qualified and expert practitioner. Keep away from children. Not for those with epilepsy or subject to seizures. Always conduct a skin patch test before using any oil on your skin.
