Warming nature improves peripheral blood flow, warms cold extremities, and supports cardiovascular health.

Digestive Stimulation

Kindles Agni and improves appetite. Carminative properties relieve gas and bloating.

Antimicrobial

Cinnamaldehyde provides broad-spectrum antimicrobial activity against bacteria, fungi, and viruses.

Frequently Asked Questions

What is the difference between Ceylon and cassia cinnamon?

Ceylon (true) cinnamon (Cinnamomum verum) is the Ayurvedic variety — delicate, multi-layered, with very low coumarin. Cassia (Cinnamomum cassia) is cheaper and contains high coumarin which can be liver-toxic in large amounts. For therapeutic use, always choose Ceylon cinnamon.

Can cinnamon help control diabetes?

Yes, multiple clinical trials show 1-6 grams of cinnamon daily can reduce fasting blood glucose by 10-29%. It improves insulin sensitivity and glucose uptake. Best used as complement to (not replacement for) diabetes management.
