Key takeaways
- Two main types: Ceylon (Cinnamomum verum, 'true cinnamon') and cassia (most common in stores).
- Cassia is high in coumarin — limit daily amounts if you drink it often.
- Studied for post-meal blood-sugar support in people with insulin resistance.
- Warming, sweet, and pairs beautifully with turmeric, ginger, and elderberry.
What is cinnamon?
Cinnamon is the dried inner bark of trees in the Cinnamomum genus. Ceylon cinnamon (Cinnamomum verum) is the softer, more delicate 'true cinnamon' from Sri Lanka; cassia cinnamon (Cinnamomum cassia) is the bolder, more common grocery-store variety from China and Indonesia.
Traditional uses
Traded across the ancient world for over 4,000 years, cinnamon has been used in Ayurveda, Traditional Chinese Medicine, and European herbalism for digestion, colds, circulation, and 'cold' constitutions.
Potential wellness benefits
Traditional uses and preliminary research — not medical claims. See safety notes below.
Post-meal blood sugar support
Meta-analyses suggest cinnamon may modestly reduce fasting glucose and post-meal blood sugar spikes in people with prediabetes or type 2 diabetes.
Antioxidant activity
Cinnamon is one of the highest-antioxidant spices per gram — proanthocyanidins and cinnamaldehyde do most of the work.
Warming digestive comfort
Traditionally used for bloating, cold hands and feet, and sluggish digestion in cold weather.
Antimicrobial activity
Cinnamaldehyde has demonstrated activity against a range of bacteria and fungi in laboratory studies.
Nutritional profile
- Cinnamaldehyde (main aromatic)
- Proanthocyanidins

How to brew cinnamon
- 1
1 Ceylon stick per 12 oz water
Simmer 10–15 minutes. The stick can be reused twice for lighter brews.
- 2
Or ½ tsp ground per cup
Whisk into hot water; ground cinnamon is stronger and cloudier.
- 3
Pair with turmeric or ginger
Cinnamon amplifies both — the combination is the base of chai and golden-milk blends.
Safety information
Cassia cinnamon is high in coumarin, which can affect the liver in high daily amounts. If you drink cinnamon tea daily, use Ceylon. Cinnamon can lower blood sugar — monitor closely if you take diabetes medication. Avoid concentrated cinnamon supplements in pregnancy.

Frequently Asked Questions
What's the difference between Ceylon and cassia?＋
Ceylon is lighter, sweeter, and much lower in coumarin. Cassia is bolder, cheaper, and higher in coumarin — fine for occasional use, not daily high doses.
How much cinnamon is safe per day?＋
For cassia: roughly ½ to 1 teaspoon per day is a common upper limit. Ceylon has no meaningful coumarin ceiling for most adults.
Does cinnamon really help blood sugar?＋
Modestly — think 'helpful nudge alongside diet and exercise,' not medication replacement.
