The cinnamon has been studied in randomized controlled trials (RCTs) for its glycemic-lowering effects, but studies have been small and show conflicting results.

Some of this work shows it may curb blood sugar by lowering insulin resistance. In one study, volunteers ate from 1 to 6 grams of cinnamon for 40 days. (One gram of ground cinnamon is about half a teaspoon.) The researchers found that cinnamon cut cholesterol by about 18% and blood sugar levels by 24%.

Yes

Anti-diabetic effect of cinnamon has been documented by experimental and clinical studies. Cinnamon lowers glucose, insulin and cholesterol in people with diabetes.

A small 2016 study of 25 people, published in the Journal of Intercultural Ethnopharmacology, found that cinnamon may be beneficial for people with poorly controlled diabetes. Participants consumed 1 g of cinnamon for 12 weeks. The result was a reduction in fasting blood sugar levels.

However, a 2013 study published in the Journal of Traditional and Complementary Medicine had a different result. The study, which used a more reliable method, had slightly more participants, at 70. The researchers found that 1 g of cinnamon per day for 30 days and 60 days offered no improvements in blood sugar levels.

Dear Hazim Al Dilaimy

While i have not seen many medical doctors recommending that and they may be right as raised glucose levels or diabetes is caused by inactivity and over eating unhealthy food so addressing this part should be the cornerstone of any treatment regimen.

But still some research supports this. However, how much ? needs complete trials on the subject before any doctor should suggest this to patients.

Bioactive Foods as Dietary Intervention for Diabetes From the Perspective of Persian Medicine

https://www.sciencedirect.com/science/article/pii/B9780128138229000047

Persian medicine (PM) is among the oldest traditional systems of medicine. It was rooted in Persian, Indian, Greek, and Egyptian culture and medicine and was practiced in Iran as well as India and Arabic countries through the history. Prevention, diagnosis, and treatments of diseases in PM are based on temperamental and humoral theories. Based on PM, diet of patients with diabetes should be offered on an individual basis. Patient's and disease Mizaj (temperament) is the main determinants of individualization of patients in PM. Besides these individualized recommendations some general healthy eating rules are suggested to these patients. Adherence to these recommendations is showed to be beneficial in improvement of glycemic and lipid outcomes of patients with diabetes in recent clinical studies. Besides dietary recommendations, many herbal supplements are suggested for patients with diabetes in PM. Psyllium, safflower, spinach, sumac, bitter apple, common purslane, barely, and cinnamon are some of examples of these recommended supplements. Multiple recent preclinical and clinical studies have supported the beneficial effects of these herbal supplements in diabetes.
