Cinnamomum species, commonly known as cinnamon, have a long history of use in traditional medicine systems such as Ayurveda, Traditional Chinese Medicine, and Unani for addressing digestive complaints, including dyspepsia (indigestion). Historical texts and ethnobotanical surveys record cinnamon bark and sometimes its essential oil as carminative agents—herbs that help relieve flatulence and soothe the digestive tract. The rationale for this use is based on cinnamon’s reputed ability to increase gastric motility and reduce intestinal gas, as well as its warming and aromatic qualities believed to stimulate digestive function.

However, modern scientific evidence supporting the efficacy of Cinnamomum for dyspepsia is limited. A few small-scale animal studies and in vitro experiments suggest cinnamon extracts may have gastroprotective and antispasmodic effects, potentially through modulation of gastric secretions and smooth muscle relaxation. Nonetheless, robust clinical trials in humans targeting dyspepsia specifically are lacking, and systematic reviews have not established cinnamon as an evidence-based treatment for this condition.

Thus, while the use of Cinnamomum for dyspepsia is well rooted in tradition, its scientific validation remains insufficient. Most recommendations for cinnamon in dyspepsia are based on traditional use rather than strong clinical evidence.
