7Cinnamon Twig

Cinnamon twig (Gui Zhi) – The Herb Used in Traditional Systems to Support Heat Circulation and Normal Perspiration RegulationCinnamon twig (Gui Zhi) is the traditional Chinese name for the dried young branches and twigs of Cinnamomum cassia (Cassia Cinnamon), a warming, aromatic herb that has been part of TCM for over 2000 years. This herb is particularly known for its ability to invigorate blood circulation, support normal heat functioning, regulate normal perspiration and especially work in early stages of normal immune challenges by promoting normal Wei Qi circulation. It is one of the most frequently used herbs in TCM's classical "Releasing Exterior" formulas.Traditional Understanding in TCM SystemsWithin traditional Chinese medicine, cinnamon twig (Gui Zhi) is described as an acrid-sweet and warm herb with aromatic character. In the TCM theoretical framework, it acts on the so‑called Heart, Lung and Urinary Bladder meridians. According to this traditional description, cinnamon twig (Gui Zhi) primarily supports normal "Yang Qi circulation" and normal "Wei Qi function" – fundamental concepts in TCM for normal thermal regulation, normal immune response and normal sweat balance.Cinnamon twig (Gui Zhi) is seen in TCM as an herb that "expels Cold," "tonifies Yang," "harmonizes Yin-and-Wei" and "releases the muscles" – meaning it helps promote normal muscle relaxation and normal blood circulation in the muscle layers. It is traditionally used to support normal immune response in early stages of cold-related discomforts, to regulate normal perspiration and to support normal blood circulation in the upper extremities.Botanical Composition and ResearchCinnamon twig (Gui Zhi) contains over 70 bioactive compounds, of which the main ones are:Cinnamaldehyde (main component, 0.5-3%) – warms and stimulates circulationCinnamic acid – anti-inflammatory actionCinnamyl alcohol – aromatic and warmingEugenol – aromatic and antimicrobialPolyphenols (quercetin, epicatechin) – antioxidantEssential oils – terpenes, linaloolCalcium oxalate and trace mineralsModern scientific research shows that cinnamon twig (Gui Zhi) components can offer diverse benefits:Normal blood circulation support: Cinnamaldehyde and related compounds can support blood vessel function, promote normal blood flow and help support normal vasodilation – aligning with traditional use for circulation.Normal immune support: Studies suggest that certain components can support normal immune cell activity and promote normal anti-pathogen response.Anti-inflammatory activity: Cinnamic acid and polyphenols can help maintain normal inflammation balance, particularly in respiratory and muscle tissue.Antioxidant action: Polyphenols possess strong free-radical-fighting action and normal oxidative-stress protection.Normal thermoregulation: Traditionally used to support normal body heat; research suggests certain components can support normal thermoregulatory functions.Normal digestion support: Warming nature helps support normal digestive function and promote normal abdominal comfort.Antimicrobial properties: Cinnamaldehyde and eugenol have demonstrated antimicrobial activity against various bacteria and fungi.Traditional Applications – TCM ContextIn traditional TCM formulas, cinnamon twig (Gui Zhi) is classically used in situations described as:Early immune challenges with cold characteristics (aversion to cold, cold sensitivity)Normal perspiration regulation (unwilling sweating or lacking sweating)Supporting normal blood circulation, particularly in upper extremitiesPain in shoulders, neck or arms related to cold stagnationSupporting normal muscle relaxationNormal heartbeat and heart comfortNormal uterus warming (for normal menstrual comfort)Normal abdominal comfort and digestion supportSupporting normal immune response in early stagesThese are traditionalist descriptions that form part of the TCM thinking system and must not be equated with medical diagnoses in the sense of European medicinal product law.Well-being and Daily UseCinnamon twig (Gui Zhi) is valued by modern users as part of a conscious wellness routine aimed at normal blood circulation, normal immune support, normal thermoregulation and overall warming energy, especially when they are cold-sensitive, have poor circulation or wish to support their normal immune response. The herb works optimally in tea, in formulas, combined with regular movement (especially warming exercises) and adequate rest.Many users see cinnamon twig (Gui Zhi) as part of an annual preventive practice – as a supportive element to help prevent normal immune challenges, alongside professional guidance and regular medical care when needed.
