Chi Shao (赤芍), commonly known as Red Peony Root, is a traditional Chinese herb used for centuries within Traditional Chinese Medicine (TCM). It is commonly associated with species of Paeonia, particularly Paeonia lactiflora and Paeonia veitchii, depending on botanical source and herbal material.
In traditional TCM terminology, Chi Shao is classified among herbs that “clear Heat and cool the Blood.” It is also traditionally described as helping to “dispel Blood stasis.” These are concepts from the traditional Chinese medical system and should not be interpreted as claims that Red Peony Root lowers body temperature, treats inflammation, improves circulation, dissolves blood clots, or treats a medical condition.
Chi Shao is the Pin Yin name for Red Peony Root. The dried root has a long history in Chinese herbal practice and is used both individually and as an ingredient in traditional multi-herb formulas.
The name Chi Shao helps distinguish this herbal material from Bai Shao, or White Peony Root. Although both are associated with peony plants and may sometimes come from closely related botanical sources, they are prepared and classified differently within traditional Chinese herbalism.
| Pin Yin Name | Chi Shao |
| Chinese Name | 赤芍 |
| Common Name | Red Peony Root |
| Botanical Sources | Paeonia lactiflora, Paeonia veitchii, and recognized botanical sources depending on the product |
| Plant Family | Paeoniaceae |
| Part Used | Root |
| Traditional Taste | Bitter |
| Traditional Nature | Slightly cold |
| Traditional Meridians | Liver |
| Traditional TCM Category | Herbs That Clear Heat and Cool the Blood |
| Common Forms | Cut root, sliced root, powder, concentrated extract, granules, and traditional formulas |
Within Traditional Chinese Medicine, Chi Shao is traditionally described using terms such as:
These phrases have specific meanings within TCM theory. They describe traditional patterns and relationships rather than modern biomedical diagnoses.
Terms such as Heat, Blood Heat, Blood stasis, and Liver should therefore be understood within their traditional TCM context.
“Clearing Heat” and “cooling the Blood” are traditional Chinese Medicine concepts. In TCM, Heat describes a pattern that may be identified through a combination of traditional signs, symptoms, tongue appearance, pulse qualities, and other observations.
Likewise, TCM Blood is a broader functional concept than blood as defined by modern anatomy and laboratory medicine.
Saying that Chi Shao traditionally “clears Heat” or “cools the Blood” does not mean that it has been established to:
Those are modern medical claims and should not be inferred from the traditional terminology.
Chi Shao is also traditionally described as “dispelling Blood stasis” or “invigorating the Blood.”
In Traditional Chinese Medicine, Blood stasis is a traditional pattern diagnosis. It is not the same thing as a blood clot, thrombosis, blocked artery, poor circulation, or cardiovascular disease.
Likewise, the traditional phrase “invigorates the Blood” should not automatically be translated into claims that Chi Shao improves circulation, thins the blood, prevents blood clots, or protects the cardiovascular system.
Chi Shao is traditionally associated with the Liver meridian.
The Liver in TCM is a functional system with meanings that extend beyond the anatomical liver. A traditional association with the Liver meridian does not mean that Chi Shao detoxifies the liver, improves liver enzymes, treats liver disease, or repairs liver damage.
Chi Shao and Bai Shao are both peony-root herbs used in Chinese herbalism, but they are considered distinct herbal medicines within TCM.
| Herb | Common Name | Traditional TCM Emphasis |
|---|---|---|
| Chi Shao | Red Peony Root | Traditionally categorized with herbs that clear Heat and cool the Blood and described as dispelling Blood stasis |
| Bai Shao | White Peony Root | Traditionally categorized as a Blood-tonifying herb and used differently within TCM formulas |
The distinction is based on traditional herbal identification, processing, preparation, and use. The names “red” and “white” should not be interpreted simply as descriptions of the visible color of the root.
Common names can sometimes be confusing when purchasing herbs. Checking the Pin Yin name, botanical identity, plant part, and product form can help distinguish one herbal material from another.
For Chi Shao, look for:
Dried Chi Shao is generally sold as pieces or slices of root. Its appearance may range from pale tan and beige to reddish-brown or darker brown depending on the botanical source, growing conditions, age of the plant, processing, and storage.
Natural herbs vary from harvest to harvest, so differences in size, shape, and color do not necessarily indicate a difference in quality.
Chi Shao has traditionally been prepared as part of Chinese herbal decoctions and multi-herb formulas.
Today, Red Peony Root may be available in several forms:
These forms are not necessarily interchangeable by weight. Concentrated extracts, for example, differ from ordinary ground herb.
Always follow the directions supplied with the specific product you purchase.
| Form | What It Is | General Preparation |
|---|---|---|
| Cut/Sliced Root | Dried pieces of Red Peony Root | Traditionally used in decoctions |
| Root Powder | Dried root ground into powder | Follow product-specific directions |
| Extract Powder | Extracted and concentrated herbal material | Follow the concentration and serving information |
| Granules | Prepared herbal extract in granular form | Follow manufacturer directions |
| Traditional Formula | Chi Shao combined with other herbs | Follow directions for the complete formula |
Researchers have identified numerous naturally occurring compounds in peony roots.
One of the best-known constituents associated with Paeonia species is paeoniflorin. Other compounds studied in peony-root materials include:
The chemical profile can vary according to species, plant part, growing conditions, processing, storage, and extraction method.
Modern research has examined Paeonia species, Red Peony Root preparations, extracts, and individual constituents such as paeoniflorin.
Areas of scientific investigation include:
These are areas of scientific investigation, not established benefits of a Red Peony Root product.
Results involving isolated compounds, concentrated extracts, laboratory cells, or animals should not automatically be applied to ordinary Chi Shao root, powder, tea, or commercial supplements.
The following PubMed searches can be used to explore published research:
Research Note: Research involving Red Peony Root, Paeonia species, specialized extracts, isolated constituents, laboratory models, or animals does not establish that a specific Chi Shao product sold by 1st Chinese Herbs will produce the same effects. Research links are provided for educational purposes and are not product claims.
When purchasing Chi Shao, compare the identifying information supplied for the specific product.
Chi Shao should be used thoughtfully, particularly when medications or medical conditions are involved.
Consult a qualified healthcare professional before using Chi Shao if you:
Do not use Chi Shao as a replacement for prescribed medication or medical treatment.
Chi Shao is the Pin Yin name for Red Peony Root, a traditional Chinese herb prepared from the root of recognized Paeonia species.
Yes. Red Peony Root is the common English name generally used for the traditional Chinese herb Chi Shao.
No. Chi Shao and Bai Shao are considered distinct herbal medicines in Traditional Chinese Medicine. Chi Shao is known as Red Peony Root, while Bai Shao is commonly called White Peony Root. Their traditional classifications and uses differ.
The root is the part traditionally used as Chi Shao.
“Clears Heat and cools the Blood” is traditional TCM terminology describing traditional patterns. It does not mean that Chi Shao has been established to lower fever, treat infection, reduce inflammation, or treat a blood disorder.
Blood stasis is a traditional TCM pattern. It is not equivalent to a blood clot, thrombosis, blocked artery, or another modern cardiovascular diagnosis.
Traditional TCM texts describe Chi Shao as “invigorating the Blood,” but this phrase should not be interpreted as proof that Red Peony Root improves circulation or treats circulatory disease.
Researchers have investigated Red Peony Root, peony extracts, and constituents such as paeoniflorin in experimental models involving inflammatory signaling. These studies do not establish that ordinary Chi Shao products treat inflammation or inflammatory diseases in people.
Paeoniflorin is one of the naturally occurring compounds found in peony roots and is frequently studied in modern phytochemical research.
No. Ordinary powder is generally dried root that has been ground, while an extract is produced through an extraction process and may be concentrated. Follow the directions for the specific product.
If you take prescription medications, particularly anticoagulant or antiplatelet medications, consult your physician or pharmacist before using Chi Shao.
Chi Shao, or Red Peony Root, has a long history within traditional Chinese herbalism and continues to be studied for its botanical chemistry and naturally occurring constituents.
When selecting Chi Shao, check the botanical species, plant part, preparation form, concentration, origin, and directions provided for the individual product.
Terms such as “Heat,” “Blood Heat,” “cool the Blood,” “Blood stasis,” “invigorate the Blood,” and “Liver meridian” are concepts used within Traditional Chinese Medicine. They do not correspond directly to modern medical diagnoses, diseases, circulatory conditions, blood disorders, or anatomical organ function.
