Cinnamon, Cinnamomum spp. [Fam. Lauraceae], is an aromatic spice isolated from the inner bark of cinnamon trees. It has been used as a medicine for several thousand years in both Eastern and Western traditions. The German Commission E approves cinnamon for treating appetite loss and indigestion. It is also used in folk medicine to alleviate gas and treat nausea and heartburn. The activity of cinnamon against nausea is attributed to catechins, which help relieve nausea. It is also a good source of powerful antioxidants. Animal studies suggest that cinnamon bark extracts taken orally may help prevent stomach ulcers. Several studies also show that cin. oil and extracts have antifungal, antibacterial and antiparasitic properties. One human study on cinnamon for treating yeast infections involved five patients with HIV infection and oral candidiasis who received a cin. extract for one week. Three of the five patients had improvement of their oral candidiasis. Controlled clinical trials are still required to determine the usefulness of cinnamon for the treatment of mucosal candidiasis. Preliminary studies also show that it is active against Helicobacter pylori, the bacteria that cause stomach ulcers, and has larvicidal properties against head lice. Test-tube studies also show that cinnamon triples the activity of insulin. Out of 49 herb, spice and medicinal plant extracts tested in rats for their effects on insulin-dependent utilization of glucose, cinnamon was the most potent. Researchers concluded that cinnamon improved glucose and insulin metabolism. Comparative experiments with cinnamon methyl-hydroxy-chalcone polymer (CMHP) and insulin, with regard to glucose uptake, glycogen synthesis and many other parameters, showed that MHCP is an effective mimetic of insulin and helps with blood sugar control. Researchers concluded that MHCP might be useful in the treatment of insulin resistance in humans and in the study of the pathways leading to glucose utilization in cells.

Active Ingredients:    

Cinnamomum spp. bark contains: Between 0.5-4% essential oil containing 60-9=80% cinnamaldehyde, up to 10% eugenol and 5-10% trans-cinnamic acid; 4-10% phenolic compounds; condensed tannins; catechins; oligomeric proanthocyanidins; other monoterpenes including limonene and alpha-terpineol; sesquiterpenes including pinene; calcium monoterpenoid oxalates; gum; mucilage; resin; starch; sugars; and traces of coumarin.

Suggested Amount:    

Unless otherwise prescribed: Cinnamon is taken as a tea using 0.5-1g of inner bark per cup of tea. Pour 150ml boiling water over a small teaspoon of the cut or powdered inner bark and strain after 10 minutes. A cup of this tea is drunk two or three times a day during meals. It can also be taken as a fluidextract 1:1 (g/ml) with the dosage of 0.7-1.3ml taken three times daily. The tincture 1:5 (g/ml) is recommended with the dosage of 3.3-6.7ml taken three times daily. These dosages correspond to 0.05-0.2ml of cinnamon essential oil.

Side Effects:    

Topical applications of cin. tea or infusions for their antimicrobial effects can cause allergic reactions and irritation of the skin and mucous membranes.
