Cinnamon  is a favourite household spice, and has been used around the world for centuries. Once traded as currency, this spice has a pleasant flavour and warm smell that has made it popular in cooking, particularly in baking and curries.
The spice comes from the inner bark of a small evergreen tree. The bark is peeled and laid in the sun to dry, where it curls up into rolls known as cinnamon sticks. Cinnamon is also available in powdered form.
Here are 6 health benefits of cinnamon:-
Cinnamon is thought to have many  medicinal and soothing property, and is used frequently in Ayurvedic and herbal medicine. The distinctive smell and flavor of cinnamon comes from the essential oils contained in the bark,  called Cinnamaldehyde. Cinnamaldehyde displays anti-viral, anti-bacterial and  anti-fungal  properties.
Cinnamon also contains large amounts of polyphenol antioxidants. Antioxidants can help protect the body from disease and are found in fruits, vegetables, herbs and spices. The antioxidants in cinnamon have been found to have anti-inflammatory effects.
Some spices, including cinnamon, have prebiotic properties  that promote the growth of beneficial bacteria and help suppress the growth of pathogenic bacteria. Therefore, including spices regularly in your diet may help improve gut health.
Cinnamon is also a useful source of  manganese and contains small amounts of calcium and fibre.
There is  some evidence  to suggest that the consumption of cinnamon  is associated with a short-term reduction in blood pressure. Although the evidence is hopeful, it would be premature to recommend cinnamon for blood pressure control until a comprehensive  randomized controlled trial  (RCT) involving a larger number of patients has been carried out.
It has been suggested that cinnamon can have a moderate effect in improving glycemic  and supporting the management of type 2 diabetes. However, conclusions are mixed, and  larger  randomized controlled trials  are needed in well-defined population groups using standardized interventions in order to definitively determine the efficacy of using cinnamon in subjects with diabetes. However, a small amount used at breakfast or in baking will not do any harm, and can be eaten as part of a balanced diet.
Cinnamon extract has been used to alleviate gastrointestinal problems in both Eastern and Western medicine for years. It has been described as a carminative, renowned for its digestive, anti-microbial  and anti-inflammatory properties. In traditional Ayurvedic medicine, cinnamon bark oil is used for treating flatulence and digestive imbalance. It is believed that the warmth of cinnamon increases blood flow and improves blood oxygen levels to help fight off illness. To alleviate digestive symptoms, cinnamon is taken as part of a hot drink (much like a tea). In this instance, it’s easier to use ground cinnamon rather than trying to grate cinnamon sticks yourself.
