Cinnamon Oil

Cinnamon Oil (Cinnamomum zeylanicum)

By Hwaa Irfan

The bark and leaves of the Cinnamon Tree is one of the longest used medicinal and culinary plants stretching back into antiquity. Known as qurfa in Arabic, kanela in Basque, yuhk gwai in Cantonese, Anoater dua in Fante, Darusita in Sanskrit, and dar chini in Farsi. The Queen of Sheba gave cinnamon to King Solomon. The ancient Greeks used cinnamon oil as an incense in their temples, while ancient Egyptians used the oil for massage of the feet, and for excessive bile.

The evergreen Cinnamon Tree is of the Lauraceae family of the plant kingdom, the same as Bay Leaf, and Camphor. Native to Sri Lanka, southwest India, and the Caribbean, it grows best in sand with a little bio-matter where there is shelter, constant rain, heat with a stable temperature. It used to be wild up until the late 1700s, but can grow up to 30 feet high as a cultivated tree.  The tree bears a thick bark, strong branches, and green-orange speckled young shoots, bearing the typical leaves of a laurel tree, which become almost leathery when mature. The tree is adorned by small white – mauve flowers that bear an oval shaped fruit. The characteristic curling of the cinnamon quill occurs while the bark is drying.

It is cultivated for commercial use mainly by Africa, Brazil, India, Jamaica, Madagascar, Mauritius, Vietnam, but the quality most esteemed in aromatherapy is from Sri Lanka. The oil has a warm, earthy but spicy aroma with an undertone of camphor. It is almost clear (yellow-brown), but if distilled purely from the leaves the oil is pale yellow in color with an odor of musk.

Adulteration is not uncommon with cinnamon essential oil. Sometimes clove leaf oil, fractions of cinnamon oil: eugenol, cinnamaldehyde are added, which changes the balance of nature’s chemistry thus affecting the therapeutic value. Sometimes, other varieties of cinnamon are added like Cassia oil, or with pure cinnamon leaf oil is replaced by clove oil, bay oil, synthetic eugenol, synthetic cinnamaldehyde or even petroleum based derivatives, so watch out for brand name, consistency (it should watery), color, and aroma! As sometimes cinnamon bark essential oil and cinnamon leaf essential oil are sold separately, look out for a richer scent for the bark oil, which has a more brown pigmentation,  whilst the leaf oil is sharper in smell, and a pale yellow in color.

Cinnamon oils have been used for several years in dental medications, and as a germicidal agent in toothpaste. As a stimulant, both the oil of the bark, and the leaf helps to maintain healthy blood circulation, heart, digestive, menstrual, and nervous system. It is also a stimulant the brain as discovered by the 2004 research carried out by Dr. P Zoladz of the Wheeling Jesuit University, U.S. boosting brain activity, as well as relieving nervous tension and short term memory loss, and that just smelling cinnamon enhances cognitive processing of the participants of the study. As a stomachic, the oil improves the digestion, and eases atonic dyspepsia by increasing the digestive process.  As a carminative the oil is effective in the treatment of diarrhea.

    • I replied before as follows:

      That’s a bit vague… besides it is best to deal with the source of the pain…
      Each oil synchronizes with particula parts of the body, so it is important to know where the pain is, and what type of pain.
      For muscular pain – pure lavender oil applied neat
      For skeletal pain – marjoram oil (add 15 drops to 1oz.of sweet almond oil) is slightly sedative, but good for dysmenorrhea, osteoarthritis
      For PMS – Chamomile oil (add 15 drops to 1oz.of sweet almond oil), but not before going to sleep – it acts as a sedative
      For sciatica – sandalwood oil (add 15 drops to 1oz.of sweet almond oil)
