Loban, also known as frankincense or olibanum, is a resin obtained from the Boswellia tree. It has been used for centuries for its aromatic properties and is commonly used in incense and perfumes. Loban has a rich, woody scent with hints of citrus and is often burned during religious and spiritual ceremonies for its purifying and calming effects.

In addition to its use as incense, loban has also been used in traditional medicine for various purposes. It has been believed to have antiseptic, anti-inflammatory, and analgesic properties. Loban resin can be crushed into a powder or used as an essential oil for topical application or inhalation.

Loban resin is obtained by making incisions in the bark of the Boswellia tree and allowing the sap to harden into droplets or tears. These tears are then collected and processed for commercial use. The Boswellia tree is native to the Arabian Peninsula and parts of Africa and India.

It's worth noting that the term "loban" can vary in its usage and regional context. In some cultures, it may refer specifically to a particular type of frankincense resin or a specific variety of Boswellia tree. Therefore, the exact properties and uses of loban may differ depending on the cultural or regional context in which it is being discussed.
