In earlier days, this tree was highly valued for its fragrance and the royal ladies used it as a beauty aid - cosmetic. In addition, practitioners of herbal medicine also recommended the balm of Gilead for treating diseases related to the urinary tract. Presently, authentic balm of Gilead is rare and its supplies possibly come from related trees (P. balsamifera) found in North America. Chemical analysis of the sweet scented resinous juice exuded by the balm of Gilead shows that its major constituents include a cluster of compounds that have resemblance to aspirin or salicylates, which are effective in providing relief from pain as well as inflammation. The fragrant oil obtained from the resin possesses an expectorant and antiseptic properties. Herbal medicine practitioners prescribe a tincture prepared with the balm of Gilead to cure aching throats, bronchitis and laryngitis. It is also applied externally as a salve and the salicylates present in the tree are known to alleviate inflammation and pain caused by arthritis and rheumatism. In fact, the same substances that ease pain are also found in the bark of the American poplars. There was a time when these pain relieving substances were taken orally as an alternative for quinine with a view to lower temperatures in fevers.
The balm of Gilead trees are cultivated only in a small part of the globe, especially the regions bordering the Red Sea.

Although the tree is cultivated rarely and it is quite difficult to grow this species, balm of Gilead has also been introduced into Italy. Balm of Gilead has a preference for damp soil having a pH of 7. The plants of this species require sufficient sunlight with a view to allow the process of photosynthesis - converting carbon dioxide into sugars in the presence of sunlight. It has been found that some plants of this species require more sunlight compared to others. Therefore, it is best to grow balm of Gilead in full sun.
