Radix Paeoniae Rubra, also known as red peony root or “赤芍” (Chì Sháo in Chinese), is a traditional herbal medicine derived from the dried roots of Paeonia lactiflora Pall. or Paeonia veitchii Lynch.
This herb has been a cornerstone of Traditional Chinese Medicine (TCM) for centuries, prized for its ability to cool the blood, alleviate pain, and treat various conditions related to heat and blood stagnation1.
In this article, we’ll delve into its origins, benefits, modern research, and practical applications, making it easier to understand why Radix Paeoniae Rubra has remained popular across generations.
What is Radix Paeoniae Rubra
Radix Paeoniae Rubra originates from Paeonia lactiflora or Paeonia veitchii, both belonging to the Ranunculaceae (buttercup) family. The roots are harvested in spring or autumn, cleaned, dried, and prepared for medicinal use. In TCM, the herb is classified as bitter and slightly cold, targeting the liver meridian. Its primary functions include clearing heat, cooling the blood, dispersing stagnation, and relieving pain2.
Historically, red peony root has been mentioned in classical Chinese texts such as Shen Nong Ben Cao Jing (Divine Farmer’s Materia Medica) and Ben Cao Gang Mu (Compendium of Materia Medica)3. These ancient texts highlight its ability to “disperse evil blood, alleviate abdominal pain, and treat heat-induced ailments.” Over the centuries, it has been used in various formulations to address conditions ranging from bruises to systemic inflammation4.

Health benefits and Medical uses
1. Clearing Heat and Cooling the Blood
Radix Paeoniae Rubra is widely recognized for its ability to reduce excessive heat in the blood. In TCM, conditions like fever, rashes, and nosebleeds are often attributed to “heat invading the blood level.” This herb works by cooling the blood and reducing symptoms such as5:
- Skin rashes caused by heat, including measles-like eruptions.
- Nosebleeds and gum bleeding due to heat-induced blood vessel rupture.
- Fever with dark red tongue or other signs of heat entering the deeper layers of the body.
2. Dispersing Blood Stasis and Relieving Pain
One of Radix Paeoniae Rubra’s most significant benefits is its ability to improve blood circulation and reduce stagnation, making it effective for6:
- Menstrual disorders like dysmenorrhea (painful periods) and amenorrhea (absence of menstruation).
- Physical trauma, such as bruises, swelling, and pain from injuries.
- Abdominal pain caused by blood stasis or “blockages” in the liver meridian.
For example, formulations like Gui Zhi Fu Ling Wan (Cinnamon Twig and Poria Pill) often include Radix Paeoniae Rubra to address menstrual irregularities and pelvic inflammation.
3. Treating Eye Conditions
In TCM, eye redness and swelling are often linked to liver heat. Radix Paeoniae Rubra, with its liver-meridian affinity, is commonly combined with other cooling herbs like chrysanthemum (Ju Hua) and prunella (Xia Ku Cao) to treat conditions such as7:
- Red, swollen eyes caused by liver fire.
- Blurred vision due to heat or stagnation in the liver meridian.
Radix Paeoniae Rubra cools blood, reduces heat, improves circulation, relieves pain, and treats menstrual disorders, injuries, and eye conditions linked to liver heat.
What Does Modern Science Say?
Modern pharmacological research has begun to validate many of the traditional claims surrounding Radix Paeoniae Rubra. Here are some key findings:
1. Anti-Inflammatory and Pain-Relieving Effects
Studies have shown that compounds in Radix Paeoniae Rubra, such as paeoniflorin and tannins, exhibit significant anti-inflammatory and analgesic (pain-relieving) properties8. These compounds reduce inflammation by inhibiting pro-inflammatory cytokines and enzymes, making it useful for conditions like arthritis, muscle pain, and even systemic inflammation.
2. Cardiovascular Protection
Radix Paeoniae Rubra has been found to improve blood flow and protect the cardiovascular system9 10. It can:
- Dilate blood vessels, improving circulation and reducing blood pressure.
- Prevent blood clots by inhibiting platelet aggregation, reducing the risk of stroke or heart attack.
- Protect the heart from ischemia (lack of blood supply) during stress or injury.
3. Neuroprotective Properties
Emerging research suggests that this herb may offer benefits for the nervous system, including protection against neurodegenerative diseases11. Its active compounds have antioxidant and anti-inflammatory effects that could reduce brain inflammation and oxidative stress, potentially aiding in conditions like Alzheimer’s disease.
4. Antimicrobial Activity
Traditional usage often involved applying Radix Paeoniae Rubra to wounds or infections12. Modern studies confirm that it has mild antimicrobial properties13, offering protection against certain bacteria and fungi.
Modern science shows Radix Paeoniae Rubra has anti-inflammatory, pain-relieving, heart-protective, brain-protective, and antimicrobial benefits.
How to Use it
Dosage and Preparation
Radix Paeoniae Rubra is typically consumed as a decoction (herbal tea) or included in herbal formulas. The typical dosage ranges from 6 to 15 grams per day, depending on the condition14. It may also be processed into capsules, powders, or tinctures for easier consumption.
Popular Formulas
- Gui Zhi Fu Ling Wan: Used for menstrual irregularities and pelvic inflammation.
- Xue Fu Zhu Yu Tang: Relieves chest pain and blood stasis.
- Dan Pi Tang: Cools blood and treats skin conditions like rashes.
Precautions
- Contraindications: This kind of herb is not recommended for individuals with “cold-induced blood stasis” or those experiencing menstrual irregularities due to deficiency rather than excess15.
- Pregnancy: Use with caution during pregnancy, as it may stimulate uterine contractions.
- Allergies: Always consult your healthcare provider if you’re allergic to peonies or related plants16.
Radix Paeoniae Rubra vs. White Peony Root
While both red peony root (Radix Paeoniae Rubra) and white peony root (Radix Paeoniae Alba) come from the same plant species, their properties and uses differ significantly17 18:
| Aspect | Radix Paeoniae Rubra (Red Peony) | Radix Paeoniae Alba (White Peony) |
|---|---|---|
| Taste and Nature | Bitter, slightly cold | Sour, slightly cold |
| Primary Function | Facilitates blood flow, clears heat | Nourishes blood, calms the liver |
| Main Usage | Treats blood stasis and heat-related issues | Addresses blood deficiency and spasms |
As the famous Chinese medical text Ben Cao Gang Mu states: “White peony nourishes, while red peony disperses.19“
