In a tradition dating to Biblical times, men rise at dawn in the rugged Cal Madow mountains of Somaliland in the Horn of Africa to scale rocky outcrops in search of the prized sap of wild frankincense trees.
When dried and burned, the sap produces a fragrant smoke which perfumes churches and mosques around the world. Frankincense, along with gold and myrrh, was brought by the Three Kings as gifts in the Gospel account of the birth of Jesus.
But now these last intact wild frankincense forests on Earth are under threat as prices have shot up in recent years with the global appetite for essential oils. Overharvesting has led to the trees dying off faster than they can replenish, putting the ancient resin trade at risk.
Harvesting frankincense is risky. The trees can grow high on cliff edges, shallow roots gripping bare rock slithering with venomous snakes. Harvesters often slip and tumble down canyon walls.
Once the resin is collected, women sort the chunks by color and size. The various classes of resin are shipped to Yemen, Saudi Arabia and eventually Europe and America. Besides its use as incense, frankincense gum is distilled into oil for use in perfumes, skin lotions, medicine and chewing gum.
