Boswellia frereana is a species of plant native to northern Somalia[1][2][3][4] where it is known as yagcar, yagar, yigaar, or yegaar.

[5].The specific epithet refers to William Edward Frere, Member of Council at Bombay.

[6] Other than its aromatic uses, the locals also use it for medicinal purposes; they make it into a paste called "malmal" and apply it on the joints to treat inflammation and arthritis.

Playfair had brought B. frereana from Somalia and cultivated it in his garden in Aden.

80% of B. frereana production is sold to Saudi Arabia where it is traditionally brought home by Muslim pilgrims.
