Boswellia Frereana is only found in Somalia where the locals call it Maydi. Frankincense Maydi, also referred to as the king of Frankincense, grows naturally in the wild. Frankincense Maydi is perfectly safe to chew as a gum. This helps fight gum diseases, strengthens teeth and freshens breath. It is used in churches, steam-distilled to produce essential oils and also widely used as chewing gum.
