Cinnamon is a popular spice derived from the inner bark of trees belonging to the Cinnamomum genus. Widely used in cooking and baking, cinnamon has also been used for centuries in traditional medicine systems. The question of whether this common kitchen spice can help relieve a cough is frequent for those seeking natural remedies. While not a replacement for conventional medicine, the history and chemical makeup of cinnamon suggest a rationale for its soothing properties on the respiratory system.
Traditional Use of Cinnamon for Respiratory Relief
The use of cinnamon to treat respiratory ailments is rooted in ancient medical practices across different cultures. Traditional Chinese Medicine (TCM) and Ayurvedic medicine in India have long incorporated cinnamon bark into formulations for cold and cough symptoms. In these systems, cinnamon is often regarded as a “warming” spice, believed to help dispel cold and support lung function.
Ayurveda notes the spice’s penetrating quality, which is thought to help liquefy mucus and act as an expectorant, easing its removal from the body. This application often involved consuming cinnamon as a warm tea or decoction, frequently combined with ingredients like honey or ginger. The traditional rationale is based on the spice’s ability to soothe throat irritation and ease breathing.
Scientific Rationale Behind Cinnamon’s Soothing Properties
Modern scientific inquiry focuses on the active chemical compounds within cinnamon, providing a biological basis for its historical use. The primary compound of interest is cinnamaldehyde, which is responsible for the spice’s distinct flavor and aroma. This compound and others in cinnamon oil have demonstrated properties that could benefit a person with a cough.
Cinnamaldehyde exhibits anti-inflammatory effects in laboratory settings, which may help reduce the irritation and swelling in the throat and bronchial passages that trigger coughing. Modulating inflammatory pathways may offer relief from persistent irritation often associated with a dry or spastic cough. Cinnamon also contains antioxidants, which support immune health and aid the body in fighting off underlying infections.
Studies indicate that cinnamaldehyde possesses broad-spectrum antimicrobial activity against bacteria and fungi, and some research suggests antiviral potential. This antimicrobial action could help address coughs caused by minor respiratory tract infections. Furthermore, the soothing warmth of a cinnamon preparation may offer a mild demulcent effect, temporarily coating the throat and reducing the cough reflex.
Practical Preparation Methods and Safety Considerations
Cinnamon can be incorporated into home remedies as a complementary treatment to ease cough symptoms. A common method is preparing a cinnamon tea by steeping a half-teaspoon of cinnamon powder or a small stick in a cup of hot water for several minutes. The soothing effect is enhanced by stirring in a teaspoon of raw honey, which is a known cough suppressant and throat soother.
Another simple preparation is mixing a half-teaspoon of cinnamon powder directly with a teaspoon of honey and taking the mixture two to three times daily. Consumers must be aware of the difference between the two main types of cinnamon: Ceylon (Cinnamomum verum) and Cassia (Cinnamomum cassia). Cassia cinnamon, which is the variety most commonly sold in supermarkets, contains significantly higher levels of a compound called coumarin.
Coumarin can cause liver toxicity when consumed in large quantities over time, particularly for individuals with pre-existing liver conditions. The European Food Safety Authority (EFSA) suggests a tolerable daily intake for coumarin, and just one teaspoon of Cassia cinnamon powder can often exceed this limit. For regular consumption, Ceylon cinnamon is the safer choice because it contains negligible amounts of coumarin.
Cassia cinnamon may also pose a risk for those taking blood-thinning medications like warfarin, as coumarin has anticoagulant properties that can increase the risk of bleeding.
