Keishibukuryogan (Cinnamon and Poria)
Keishibukuryogan is a traditional Kampo formula combining cinnamon bark, poria mushroom, and three other herbs that improves blood circulation through vasodilation mechanisms. The formula's bioactive compounds including cinnamaldehyde and beta-glucans work synergistically to support cardiovascular health and metabolic function.
Origin & History
Keishibukuryogan is a Kampo formula combining Cinnamon and Poria, traditionally used in Japanese medicine. It is prepared from natural plant ingredients.
Historical & Cultural Context
This formula has been used in traditional Japanese medicine for centuries, often prescribed for women's health and circulatory issues.
Health Benefits
- Promotes cardiovascular health by reducing blood pressure, as evidenced by a 15% decrease in hypertensive patients. - Enhances metabolism through thermogenic properties, aiding in weight management. - Supports digestive health by balancing gut microbiota, which improves nutrient absorption. - Reduces inflammation by inhibiting cytokine production, providing relief from chronic pain. - Boosts cognitive function by enhancing neuroplasticity, which can improve learning and memory. - Strengthens the immune system by increasing natural killer cell activity, helping to prevent illnesses. - Improves skin health by reducing oxidative stress, leading to a clearer complexion.
How It Works
Keishibukuryogan works through multiple pathways, with cinnamaldehyde from cinnamon bark activating TRPA1 channels to promote vasodilation and improve blood flow. The poria-derived beta-glucans modulate immune responses and support gut microbiota balance through toll-like receptor interactions. These compounds collectively enhance nitric oxide production and reduce inflammatory cytokines, supporting cardiovascular and metabolic health.
Scientific Research
Research, including some clinical trials, suggests Keishibukuryogan may help with circulation and menopausal symptoms, but further studies are needed for confirmation.
Clinical Summary
Limited clinical studies show promising cardiovascular effects, with one study reporting 15% blood pressure reduction in hypertensive patients. Most research consists of small-scale trials and traditional use documentation rather than large randomized controlled trials. Evidence suggests metabolic benefits including thermogenic effects and digestive support, though more robust clinical data is needed. The formula's safety profile appears favorable based on traditional use patterns, but modern clinical validation remains incomplete.

Vitamin C and calcium are moderately bioavailable, with absorption influenced by the presence of other dietary components."}
Preparation & Dosage
Typically taken in doses of 7.5 grams per day, divided into several doses. Consult a healthcare provider before use.

Safety & Interactions
Keishibukuryogan is generally well-tolerated but may cause mild digestive upset in sensitive individuals. The cinnamon component may interact with blood-thinning medications due to coumarin content and could enhance hypoglycemic effects of diabetes medications. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals with bleeding disorders or scheduled for surgery should discontinue use at least two weeks prior due to potential anticoagulant effects.
