Cassia bark (Cinnamomum cassia), also known as Chinese cinnamon, has been used for centuries in traditional medicine systems, particularly Traditional Chinese Medicine (TCM), to support digestion and the Stomach system. In TCM, cassia bark is believed to "warm the middle," dispel cold, and alleviate symptoms such as abdominal pain and indigestion. It is a component of several classic herbal formulas intended to treat digestive disturbances, bloating, and stomach discomfort.

Scientific research on cassia bark’s direct effects on the human stomach is limited. Some laboratory and animal studies suggest that cassia and its constituents (such as cinnamaldehyde) may have gastroprotective, anti-inflammatory, and antimicrobial properties, which could theoretically benefit stomach health. However, robust clinical trials in humans are lacking, and most evidence supporting its use for the stomach is historical and anecdotal rather than scientifically validated.

In summary, while there are plausible mechanisms and a foundation in traditional use, the evidence for cassia bark supporting the stomach system is primarily traditional, with moderate support based on longstanding herbal practice rather than strong scientific proof.
