Overview

Overview Information

Cinnamon bark comes from a tree called Cinnamomum verum. People use the bark to make medicine.

Cinnamon bark is used for gastrointestinal (GI) upset, diarrhea, and gas. It is also used for stimulating appetite; for hayfever (allergic rhinitis); for infections caused by bacteria and parasitic worms; for oral yeast infections (thrush); and for menstrual cramps, the common cold, and the flu (influenza).

Cinnamon bark, as part of a multi-ingredient preparation, is applied to the penis for premature ejaculation. It is also used as a mouth rinse to prevent mouth sores in people with dentures.

In foods, cinnamon is used as a spice and as a flavoring agent in beverages.

In manufacturing, cinnamon oil is used in small amounts in toothpaste, mouthwashes, gargles, lotions, liniments, soaps, detergents, and other pharmaceutical products and cosmetics.

There are lots of different types of cinnamon. Cinnamomum verum (Ceylon cinnamon) and Cinnamomum aromaticum (Cassia cinnamon or Chinese cinnamon) are commonly used. In many cases, the cinnamon spice purchased in food stores contains a combination of these different types of cinnamon. See the separate listing for Cassia Cinnamon.

How does it work?

The oils found in cinnamon bark are thought to reduce spasms, reduce gas (flatulence), stimulate the appetite, and fight bacteria and fungi. Cinnamon might also decrease blood pressure and blood lipids. Cinnamon bark chemicals might work like insulin to lower blood sugar. However, these effects are thought to be fairly weak.

There are also ingredients in cinnamon bark called tannins that might help wounds by acting as an astringent, and also prevent diarrhea.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Hay fever (allergic rhinitis). Research shows that taking cinnamon bark extract along with acerola fruit concentrate and powdered Spanish needles can reduce hay fever symptoms in people with seasonal allergies.
  • Yeast infection (candidiasis). Early research shows that taking lozenges containing cinnamon bark for one week might improve yeast infections in the mouth, a condition also known as thrush, in some people with HIV.
  • Irritable bowel syndrome (IBS). Early research shows that consuming a formula containing cinnamon bark, bilberry, slippery elm bark, and agrimony twice daily for 3 weeks can increase bowel movements and reduce stomach pain, bloating and straining in people with IBS.
  • Mouth sores from dentures. Early research shows that rinsing the mouth with 10 mL of mouthwash containing cinnamon bark leaf oil helps prevent mouth sores in some people with dentures.
  • Premature ejaculation. Some research shows that applying a specific cream containing cinnamon bark and many other ingredients might prevent premature ejaculation.
  • Food poisoning (Salmonella infection). Consuming cinnamon bark might help treat a salmonella infection.
  • Appetite stimulation.
  • Common cold.
  • Diabetes.
  • Diarrhea.
  • Gas (flatulence).
  • Infections.
  • Influenza.
  • Menstrual discomfort.
  • Spasms.
  • Upset stomach.
  • Worm infestations.
  • Other conditions.
More evidence is needed to rate cinnamon bark for these uses.

Side Effects

Side Effects & Safety

Consuming cinnamon bark in food amounts is LIKELY SAFE. Cinnamon bark is POSSIBLY SAFE for most people when taken by mouth in amounts used for medicine. These amounts are slightly higher than amounts found in food. However, cinnamon bark is POSSIBLY UNSAFE when taken by mouth in large amounts. Also, taking cinnamon oil by mouth is POSSIBLY UNSAFE. The oil can be irritating to the skin and mucous membranes, including the stomach, intestine, and urinary tract. It can cause side effects such as diarrhea, vomiting, dizziness, drowsiness, and others.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Consuming cinnamon bark is LIKELY SAFE when taken in food amounts during pregnancy and breast-feeding. Do not take larger amounts of cinnamon bark if you are pregnant or breast-feeding. Not enough is known about the safety of taking larger amounts.

Diabetes: Cinnamon bark might lower blood sugar in people with type 2 diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use cinnamon bark.

Low blood pressure: Cinnamon bark might lower blood pressure. Taking cinnamon bark might cause blood pressure to drop too low in people who already have low blood pressure.

Surgery: Cinnamon bark can affect blood pressure and blood sugar levels and might interfere with blood pressure and blood sugar control during and after surgery. Stop taking cinnamon at least 2 weeks before a scheduled surgery.

  • Medications for diabetes (Antidiabetes drugs) interacts with CINNAMON bark

    Cinnamon bark might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking cinnamon bark along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.<br/><br/> Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

Dosing

Dosing

The appropriate dose of cinnamon bark depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for cinnamon bark. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
