Chinese: gui zhi

English: cinnamon twig, cassia twig

Pharmaceutical: Cinnamomi Ramulus

Properties: Acrid, sweet, warm

Standard Species: Cinnamomum cassia Presl.

Note: Japanese Pharmacopoeia includes Keihi (gui pi – Cinnamomi Cortex) only.  Therefore, Keihi is often used in many formulas even when Keishi (gui zhi –  Cinnamomi Ramulus) is traditionally indicated. In traditional Chinese medicine (TCM) however, two herbs are considered to have different therapeutic properties and their applications have been clearly differentiated.
