Cinnamon, the inner bark of the Cinnamomum verum tree (syn. Cinnamomum zeylanicum and Laurus cinnamomum), is a spice used for many centuries throughout the world – originally only by royalty, due to the price. The origin was kept secret from the West until the early sixteenth century, when Portuguese traders landed in Sri Lanka.
Although cinnamon trees are grown commercially in many parts of the East, even as recently as 2006 90% of the production of cinnamon was carried out in Sri Lanka.
Obviously, unless you are lucky enough to live in one of the areas with a similar climate, you won’t be growing your own cinnamon tree. But you can still use it by purchasing good quality cinnamon, which is easy to tell from the inferior cassia if you buy it in “quills” rather than ground (see picture left). It keeps better like this as well.
If you do live in a cinnamon-producing area, you are still probably better off purchasing rather than growing your own, which involves coppicing cinnamon trees, removing the bark from the resulting branches, immediately discarding the outer bark and drying the inner, which rolls up as it dries to form the characteristic quills.
Edit: I just came across this YouTube video on Reddit, which seems to demonstrate beyond any doubt that cinnamon works as an effective ant-repellent.
Don’t believe propaganda that says a teaspoon of cinnamon contains as many antioxidants as a half cup of blueberries or a whole cup of pomegranate juice. This seemed extremely unlikely to me, so I researched the actual nutrient content of each. I’m afraid that you still have to eat those blueberries or drink that pomegranate juice. Cinnamon does contain quite a lot of nutrients, for sure, in particular manganese, calcium and iron, but a teaspoonful a day is not going to fulfil your antioxidant requirements, or go anywhere near doing that, sorry.
Having shot that fox, there is strong research evidence that cinnamon is very helpful to people suffering from diabetes – as little as a half teaspoonful a day lowers blood sugar levels, as well as cholesterol and triglyceride in Type 2 diabetics not taking insulin. Other studies show the same quantity can lower LDL cholesterol in the general population.
Copenhagen researchers gave arthritis patients a half teaspoon of cinnamon powder mixed with a tablespoon of honey for breakfast every day, and within a week, their pain was significantly reduced – after a month they could walk without pain.
It’s also prescribed in Germany for appetite loss and indigestion.
Other conditions which are helped by cinnamon include COPD, poor circulation in hands and feet, all kinds of digestive disorders including infantile diarrhea, high blood pressure, muscle cramps, athlete’s foot and medication-resistant yeast infections.
For athlete’s foot and other external fungal infections you can use a wash – make a standard infusion using a half teaspoon of freshly ground cinnamon to 250ml (1 US cup, 8 fl oz) of boiling water, allow to cool before use. For other purposes, you can add a half teaspoon of cinnamon to honey (like the Danish study did), or you could just chew the powder and swallow it (as Chinese herbalists often recommend), or make a standard infusion and drink it (hot or cold). Another method would be to obtain empty capsules from a herbal supplier and fill each one with a quarter or half teaspoon of cinnamon so that you can take one or two in the morning or at night along with your regular supplementation. There are also ready made cinnamon capsules available, see below.
There are two types of cinnamon essential oil: bark oil, which is toxic and should not be used for aromatherapy under any circumstances, and leaf oil which can be used diluted with carrier oil for skin infections and as a stimulant to increase blood flow and sexual appetite. Do a patch test before using on the skin and use in moderation. It can also be used neat (wear gloves) to kill mosquitoes and their larvae, and in an oil burner as a room freshener and mosquito repellent. Even the leaf oil is irritant and should be avoided during pregnancy. Never use internally, even in cooking.
