Cassia bark (Cinnamomum cassia) contains 1-3% volatile oil with trans-cinnamaldehyde (55-85%) that inhibits inflammatory pathways including NF-κB, MAPK, and COX-2 expression in macrophages at 200 µg/mL. The bark demonstrates antioxidant activity with DPPH scavenging at 0.072 mg/mL and reduces inflammatory markers like TNF-α and PGE2 in animal models.
Reported Benefits (Provisional)
Origin & History
Cassia (Cinnamomum cassia) is an aromatic tree native to Southern China and Southeast Asia. Its bark has been prized for millennia in traditional medicine and culinary arts for its warm, sweet-spicy flavor and profound metabolic benefits.
Research Narrative (Provisional)
Numerous studies, including clinical trials and meta-analyses, support Cassia bark's efficacy in enhancing insulin sensitivity and regulating blood sugar, primarily due to cinnamaldehyde. Research also highlights its cardiovascular benefits, antioxidant properties, and antimicrobial effects, validating its traditional uses.
Preparation & Dosage

Nutritional Profile
- Bioactives: Rich in cinnamaldehyde (primary active), polyphenols, coumarin, and eugenol. - Minerals: Contains calcium, iron, and magnesium. - Vitamins: Provides B vitamins and dietary fiber. - Phytochemicals: Offers mild analgesic, respiratory-supportive, and potent antioxidant properties.
Reported Mechanism (Provisional)
Trans-cinnamaldehyde (55-85% of essential oil) suppresses inflammatory responses by blocking NF-κB nuclear translocation, inhibiting MAPK pathways (ERK, JNK, p38), and preventing Toll-like receptor 4 oligomerization in RAW264.7 macrophages. The compound also inhibits iNOS and COX-2 expression while reducing IκBα degradation and STAT3 activation. Additional bioactive compounds including o-methoxy-cinnamaldehyde (8.79%) and cinnamic acid contribute to antioxidant effects through DPPH and ABTS radical scavenging mechanisms.
Clinical Narrative (Provisional)
Current evidence is primarily limited to in vitro and animal studies, with no robust human clinical trials providing specific numerical outcomes for cassia bark extract. In vivo studies show cinnamaldehyde reduced carrageenan-induced paw edema and decreased inflammatory markers TNF-α and PGE2 while boosting antioxidant enzymes CAT, SOD, and GPx. One review noted no significant effect on HbA1c levels in type 2 diabetes patients from cassia cinnamon trials, unlike other cinnamon species. Antioxidant studies demonstrate inhibition rates of 81.5% at 1.0 µg/µL against H2O2-induced oxidative stress, though human clinical validation remains lacking.
