Frankincense Resin (Ru Xiang)

OlibanumSince ancient times, frankincense, also known as olibanum and Ru Xiang in mandarin, has come across as an aromatic resin that is holy and pretty inspiring. That is the reason why frankincense resin is frequently burned in many ritual occasions. Besides of religious reason, people living in the Mediterranean region views it as one of the best incense sticks as well as the best beauty products; Egyptians had used frankincense for mummification; Chinese use it medicinally to treat skin ulcer, regulate Qi, and promote blood circulation. According to legend, gold, frankincense and myrrh were given as a gift when Jesus Christ was born. As can be seen from the above record in Bible frankincense is a very expensive item since it was mentioned in the same breath with gold and frankincense. So here comes the question as follows.

What is frankincense?

Many trees would secrete liquid grease from the scars to protect themselves once they were cut by knives, damaged by insects, or subjected to fungal infection. This concretionary exudation is usually called resin. Hence, the aromatic resin produced from trees of the genus Boswellia in family Burseraceae is given the name frankincense, which comes from Old French “franc encens”, literally “high-quality incense”, since it is a common raw material in producing perfume and incense. It can be obtained in several Boswellia trees, especially the species of Boswellia carteri, Boswellia sacra, Boswellia bhaw-dajiana (Burseraceae), Boswellia frereana, and Boswellia thurifera. Other names of it include Frankincense Carterii, Boswellia Resin, Resina Boswelliae Carterii, Resina Olibani, and more. They mainly grow, wild or cultivated, in Somalia, Ethiopia and other places in Africa. The frankincense olibanum resin is usually harvested in spring and summer. The steps are to upwards slash the bark of the trunk, let the resin ooze gently out of the cut, wait it to harden, and finally collect the hardened resins a few days later. Medicinally it is used broken and raw, but often fried when orally taken.

Boswellia carterii is a dwarf shrub, usually 4 to 5 meters or rarely up to 6 meters in height. Stout trunk is pale brown, papery, and with smooth bark. Bough bark is scaly and gradually peeled off. Odd pinnate leaf is alternate, 15 to 25cm long; leaflets are 15 to 21 in number, bigger in sizes from down to up, long oval shaped, 3.5cm long, or even 7.5cm long and 1.5cm wide atop, and with obtuse apex, rounded, nearly heart-shaped or truncate base; margin is entire or with crenature. Small flowers sparsely arranged in racemes; cup-shaped calyx is 5-parted and with triangular-ovate lobes; petals are 5, pale yellow, oval, 2 times of the length of sepals, and with acute apex; stamens are 10, grown outside of flower disc, and with short filaments; ovary is superior and with 3 to 4 rooms and capitate stigma that is slightly 3-lobed. Drupe is obovate, about 1cm long, and with 3 edges, blunt end, fleshy pericarp, and 1 seed in each room. Bloom time is in April.

Currently the population of various Boswellia trees is declining sharply due to a number of reasons, such as over-collection, grazing, land reclamation, spontaneous fire, insect attack, political instability in northeastern Africa and the Arab world, and so on. Because of the harsh environment the survivals have hard time bearing seeds. What’s worse, the seeds are less likely to successfully burgeon forth even though they have been borne. As a result, frankincense tree is endangered today. What a pity that it is to witness its extinction comes at some point and we can do nothing to stop it.

It contains 60% to 70% resin, 27% to 35% gum, and 3% to 8 % volatile oil. Main chemical constituents of resin are a, β-boswellic acids, O-acetyl-β-boswellic acids, O-acetyl-a-boswellic acid, dihydroroburic acid, epilupeol acetate, tirucallol, etc. Rankincense gum contains Arabic acid, calcium salt, magnesium salts, bassorin, bitter substances, etc. Pale yellow aromatic volatile oil contains pinene, rac-limonene, a, β-phellandrene, a-campholenaldehyde, cuminaldehyde (cumaldehyde), carvotanacetone, phellandral, o-methylacetophenone, carvone, perillaldehyde, eucarvone, piperitone, nopinone, cryptone, verbenone, γ-campholenaldehyde, thujone, myrtenic acid, myrtenal, pinocamphone, a-amyrenone, 11-keto-a-amyrenone, 5-hydroxy-p-menth-6-en -2-one, 10-hydroxy-4-cadi-nen-3-one, etc.

Frankincense resin benefits

As mentioned previously, this resin comes with a pleasant and soothing aroma. Just like its famous rival of nag champa incense, burning frankincense resin can emit smoke with a distinct scent too. So it is frequently used to make herbal incense for medical purpose since the smoke is quite versatile – drive away mosquitoes, treat respiratory diseases and joint pain, and reduce a depressed or irritable mood. And today some related studies show that it also helps several cancers, such as breast cancer, bladder cancer, brain tumor, skin cancer, etc.

But in different regions, the frankincense uses are different. In ancient time, the Egyptians and the Hebrews burned frankincense resin in the ritual in order to worship God in the temple. In fact, this traditional, ancient custom is still practiced today in some churches. In addition, viewed as the life energy focus of Boswellia tree, it could be used to fumigate and disinfect the patients in order to expel the “sickness demons” out of the body.

As everyone knows frankincense oil is distilled and extracted from its resin. It is colorless or pale yellow in color and deep, refreshing in odor that smells like camphor. As a matter of fact, as early as ancient Egypt, the Egyptians already knew how to extract its essence from wood and bark by distillation and exerted frankincense essential oil to make beauty products, for example skin rejuvenation lotion.

It is generally acknowledged that aroma is where frankincense’s real medical value is rooted in. And Chinese found its amazing healing properties in the treatment of scrofula and leprosy. However, it is not the end of its story.

    It is said above that frankincense (ru xiang) should be avoided in those with sensitive stomachs. I had a problem with my gut in which there was palpable bloating and tremendous gas after every meal. Nothing helped, not probiotics, not enzymes, peppermint, and a host of other things I tried that did not work. I bought some ru xiang from Plumflower-their 5:1 concentrate powder, and took a small spoonful after a meal. Immediately my gut was calmed, and it stayed calm. I still use it after every meal. Perhaps later I can reduce my dose, but for now I am taking no chances. This has been a God-send to me. I have also suffered from ulcers periodically, have scar tissue in my gut, but with the ru xiang I am doing much better and feel normal. So I am not so sure that frankincense should be avoided by those with stomach problems. I can now sleep through the night without discomfort, too.
