Cassia bark (Cinnamomum cassia) has a long history of use in traditional medicine systems, particularly within Traditional Chinese Medicine (TCM) and Ayurveda. In TCM, cassia bark—often referred to as "Rou Gui"—is considered a warming herb that can stimulate the digestive system and is sometimes used to regulate appetite and metabolism. While the primary traditional uses focus on treating coldness, pain, and stagnation, some texts and practitioners suggest it may help manage excessive appetite by supporting healthy digestive function and addressing imbalances that could lead to overeating. However, there is limited direct scientific evidence to support cassia bark’s efficacy for reducing or regulating excessive appetite. Most modern research on cassia bark centers around its potential roles in blood sugar regulation and metabolic function, rather than direct appetite suppression or control. Some animal studies have hinted that certain compounds in cassia, such as cinnamaldehyde, may influence satiety or gut hormones, but these findings are preliminary and do not constitute robust clinical evidence. In summary, the use of cassia bark for managing excessive appetite is primarily supported by tradition and anecdotal evidence, with only indirect or minimal scientific support at this time. Anyone considering cassia bark for appetite-related issues should consult with a healthcare professional and be aware of potential side effects, especially related to coumarin content.
