Cinnamon is one of the world’s most popular spices. It is also one of the oldest herbal medicines: some Chinese texts have mentioned its use in herbal remedies more than 4,000 years ago.

Cinnamon comes from the cinnamon tree, which grows in tropical areas, including parties of India, China, Madagascar, Brazil and the Caribbean. The tree’s inner bark and essential oil are used to make herbal products. Pieces of the bark may be sold individually, or the bark may be crushed and sold in a powdered form.

The medicinal effects of cinnamon are attributed to terpenoids, substances found in the tree’s essential oil. Small studies conducted on AIDS patients have found that cinnamon oil as a potent anti-fungal, helping rid the body of oral candida infections. Cinnamon has also been shown to fight the bacteria that causes most ulcers. Test-tube studies have found that other substances in the essential oil, diterpenes, may help reduce allergies.
