The word 'louben' is perhaps cognate with 'Olibanum', or frankincense.
The tree, which grows through Arab lands, is Boswellia thurifera.

We have a bag light coloured "tears" of resin the label of which says
LOUBEN.
It is used in Tunisia as chewin-gum.
Would somebody have any idea of the botanical name of the tree it comes from
?
Thanks in advance
