A Christmas tradition that can be traced back to the story of Jesus’s birth in Bethlehem is the exchange of gifts.
The Bible records that three wise men took him gifts of gold, frankincense and myrrh.

Gold we all know, but where on earth does one find the other two in the present day?
The search for them led me to Wajir in north-eastern Kenya.
Half an hour’s drive from the town there is a 20-acre (eight-hectare) plantation of myrrh trees and boswelia, the tree that produces frankincense.
Medicinal
Hareth Hassan has been tending the trees for 15 years since inheriting the plantation from his father.
“We treasure these trees because their resin has many medicinal uses,” he says.

“We spray it in our homes to repel snakes and insects. Also when someone gets sick, we apply it on them, for example when you feel pain on the hand. And if you break a limb, before correcting it, we apply myrrh on the affected area.”

What are they used for?

Frankincense – locally it is chewed as gum, ground into powder and burnt as incense, used as a perfume and for a wide range of ailments; commercially it is used as an essential oil in perfume, cosmetic and flavour industries
Myrrh – Egyptians used it for embalming mummies, and in the Bible it is said to have been mixed with wine to be used as a painkiller for Jesus; locally used as an ink in Islamic schools, burned to repel insects and snakes, as a medicine; commercially used in perfumes, flavours and cosmetics (such as stomach remedies, mouthwashes and toothpaste)

Four collectors arrive carrying an axe and recycled plastic containers. They walk around the farm looking for resin that is ready for harvesting.
They also make shallow cuts on the tree trunks and branches to stimulate the production of myrrh resin.
Mr Hassan works closely with Ambia Osman, an officer from the Kenya Forests Service.
“These trees grow naturally and so it’s important to conserve them,” says Ms Osman, who says she teaches the collectors not to overtap the resins.
“But they don’t make much because they sell it raw,” she adds.
We drive back to Wajir town, a small but busy business centre. Ms Osman shows us several shops that stock myrrh, frankincense and other natural products.
