Most people know cinnamon as a cozy, comforting spice—something to sprinkle on lattes or oatmeal. In traditional Chinese medicine (TCM), however, cinnamon has been revered for centuries as a powerful healing herb used for far more than flavoring food. With warming properties and the ability to boost circulation and energy, cinnamon holds a vital role in supporting heart health, digestion, metabolism, and vitality.
Whether you’re struggling with cold hands and feet, sluggish digestion, or blood sugar swings, this time-tested spice may offer more benefits than you think.
Warms the Body, Boosts Vital Energy
In TCM, cinnamon is prized for its warming nature and sweet, pungent flavor. It’s believed to stimulate several key meridians—energy pathways linked to the kidneys, spleen, heart, and liver.
Cinnamon is traditionally used to boost yang energy, representing warmth, activity, and vitality in the body. By enhancing yang, cinnamon helps warm the body, dispel internal cold, improve blood circulation, and clear energy blockages.
One of cinnamon’s most distinctive qualities in TCM is its ability to strengthen kidney yang and ignite the “Gate of Life” (Mingmen)—a vital source of life energy located between the kidneys in the lower back region. In TCM theory, this internal fire powers the body’s core functions. Think of the kidneys as a furnace: Yang is the fire, and yin is the water. The balance between the two keeps the body running smoothly.
When this internal fire is weak, people often feel cold, tired, or prone to poor circulation. Strengthening kidney yang with cinnamon helps maintain body warmth, energizes the system, and may reduce the risk of blood clots.
Warming Cold Hands and Feet
I often encounter patients—particularly vegetarians—who experience persistent coldness in their hands and feet. The condition often persists even with the regular inclusion of fresh ginger and other warming foods in their meals.
In such cases, I typically recommend adding a small amount of cinnamon powder (no more than 0.1 ounces per day) to their food. In most instances, within a week, their extremities feel noticeably warmer, and they become less sensitive to cold.
This improvement reflects cinnamon’s unique ability in TCM to strengthen kidney yang and rekindle the fire of the Gate of Life—a key source of the body’s warmth and energy located between the kidneys in the lower back.
Relieves Angina, Provides Cardiovascular Support
In TCM, cinnamon has long been valued for improving circulation. One of its uses includes relieving angina—a type of chest pain caused by reduced blood flow to the heart, often linked to coronary artery disease.
Cinnamon may help increase oxygen delivery to the heart muscle by enhancing blood flow and easing discomfort during angina episodes.
Modern research supports some of these traditional insights. Research has shown that cinnamon can help lower blood lipid levels, prevent thrombosis, protect vascular endothelial function, and reduce the risk of atherosclerosis—a condition marked by plaque buildup in the arteries.
Supports Digestive Health
People with spleen and stomach yang deficiency—a common TCM diagnosis—often present with symptoms such as poor appetite, bloating, stomach discomfort, acid reflux, and constipation.
Although similar symptoms may also occur in those with excess heat in the digestive system, the two conditions can typically be differentiated by the presence or absence of thirst: Those with yang deficiency usually do not feel thirsty or have a desire to drink, while those with excess heat often experience a dry mouth and pronounced thirst.
For people with spleen and stomach yang deficiency, adding a small amount of cinnamon to gastrointestinal herbal prescriptions can help stimulate digestive motility and relieve symptoms.
Regulates Blood Sugar
Cinnamon contains polyphenolic compounds that may mimic certain effects of insulin, potentially helping to lower blood sugar levels.
A Swedish clinical trial found that cinnamon can enhance insulin sensitivity. Compared with when they ate meals without cinnamon, healthy participants eating meals containing 3 grams of cinnamon showed reduced insulin levels after eating without a corresponding increase in blood glucose.
Researchers suggest that cinnamon may stimulate insulin receptors, thereby decreasing the body’s demand for insulin—an effect that may be beneficial for preventing and managing Type 2 diabetes.
A 2024 trial conducted in the United States reported that cinnamon helped reduce post-meal blood sugar spikes and also exhibited lipid-lowering effects in obese adults with prediabetes.
Various cinnamon-based products—including capsules, oral solutions, and powders—have been developed in the United States and Europe as functional supplements to help regulate blood sugar.
Recommended Dosage
Adding a small amount of cinnamon—approximately 1/4 teaspoon—to herbal formulas that tonify qi and blood can enhance their overall effectiveness. Cinnamon helps stimulate circulation and warm the blood and vessels, promoting smoother flow throughout the body.
For symptoms associated with kidney yang deficiency or weakened Gate of Life fire—such as cold intolerance, cold limbs, lower back and knee soreness, impotence, infertility due to uterine cold (a condition of yang energy deficiency in the uterus and surrounding pelvic area, leading to a feeling of coldness and impaired function), frequent nighttime urination, or rheumatic joint pain—a higher dosage of approximately 1/2 a teaspoon to 1 teaspoon may be used.
Precautions for Taking Cinnamon
While beneficial for many, cinnamon isn’t suitable for everyone and should be avoided by the following:
- People with yin deficiency leading to fire hyperactivity, characterized by symptoms such as dry mouth and throat, irritability, night sweats, afternoon fevers, restless sleep, and excessive dreaming
- Pregnant women, as cinnamon has a strong warming and stimulating nature
- People with bleeding disorders, as cinnamon may increase the risk of bleeding or exacerbate related symptoms
