However, their differences lie in: Wild red peony root is used medicinally in its raw form, excelling at cooling the blood and expelling stasis; cultivated white peony root undergoes peeling, boiling, slicing, and sun-drying, excelling at nourishing blood and replenishing yin. Among these, peony root from Zhejiang Province is considered the finest quality, known as "Hangzhou White Peony Root."
Hundreds of ancient formulas feature white peony root as a primary ingredient. For instance, "Cinnamon Twig Decoction" uses peony root to harmonize the nutritive and defensive qi of the skin surface; "Scutellaria Decoction" employs it to harmonize the nutritive qi within the abdomen; and "Fried Licorice Decoction" utilizes it to replenish yin fluids in the blood vessels. In gynecological and obstetric clinical practice, peony root finds even broader application.Below are several real-life examples.
Danggui Shaoyao San
Xiao Jiang, a 26-year-old netizen, had suffered from severe abdominal pain during her menstrual period for three years. Despite multiple doctor visits, no relief was found. In recent years, the pain worsened to an unbearable level, often causing her limbs to grow cold. Her flow was scant, dark in color with clots, accompanied by aching in her lower back and waist.During her monthly period, she was tormented to the point of losing her appetite and struggling to sleep. Later, upon a friend's recommendation, she tried some Danggui Shaoyao San. To her surprise, by the second month, her menstrual cramps were significantly less severe, and her back pain had eased. More importantly, as her menstrual flow normalized, Xiao Jiang's complexion regained its former rosy glow, and her mood improved considerably.So why do peony and angelica treat menstrual cramps? The Danggui Shaoyao San formula—comprising peony, angelica, white atractylodes, polygonum, alisma, and chuanxiong—promotes blood circulation, removes stasis, drains dampness, generates new fluids, regulates qi and blood, and alleviates pain. It avoids extremes and lacks drying, heating, or clogging properties.Therefore, this formula can be modified and applied to treat various gynecological disorders caused by the mutual entanglement of dampness and stasis, concurrent blood and fluid disorders, disharmony of qi and blood, liver-spleen disharmony, or spleen retention of dampness—with remarkable efficacy.
Cinnamon Twig and Peony Decoction
A friend of mine once suffered greatly from dysmenorrhea. During her menstrual period, she experienced pain in the lower abdomen and waist, with the first day being the most severe—so much so that bed rest was necessary.During her period, her complexion was poor, her hands and feet were cold, she felt exhausted, experienced dizziness upon standing, had acne on her face, and felt tenderness when pressing on both sides below her navel. Her tongue was moist with no coating. One summer vacation, her mother insisted on brewing Cinnamon Twig and Peony Root Decoction for her. After three months, her menstrual cramps never returned.
Gui Zhi Sha Yao Tang is actually quite simple to prepare. Its main ingredients are: Cinnamon Twig (9g), Peony Root (18g), Fried Licorice Root (6g), Jujube (3 pieces), and Ginger (9g). Though made with basic materials, this decoction effectively warms the spleen, harmonizes the middle burner, and alleviates acute pain. Those who experience menstrual cramps may wish to give it a try.
Peony's Multiple Medicinal Values: Comprehensive Care for Women
White Peony Root paired with Prepared Rehmannia Root nourishes both liver and kidneys. For blood and qi deficiency—manifesting as delayed puberty, late menstruation, or scant, pale flow—use Four Substances Decoction with peony and rehmannia as primary herbs.Typically, 30g of prepared rehmannia root (substitute charcoal-processed rehmannia for those with weak spleen/stomach function) and 12g of stir-fried white peony root are used to greatly replenish yin blood and nourish kidney essence.Chuanxiong is renowned for tonifying liver qi. For those with excess qi, sour substances are essential to restrain it. Bai Shao, with its sour taste, is known as the "liquid that restrains the liver." Using 9 grams each of Bai Shao and Chuanxiong (both lightly stir-fried), this combination invigorates qi transformation and regulates menstruation for those with irregular qi movement, erratic menstrual cycles, or difficult flow.For heavy menstrual flow, use 12 grams of roasted white peony root and 4.5 grams of roasted chuanxiong rhizome. The combination of peony root and chaihu (Bupleurum root) finds its most potent expression in the ancient formula "Xiaoyao San" (Free and Easy Wanderer Powder).Ancient physicians held that women's health fundamentally relies on blood. Often, blood is deficient while qi is excessive. When emotional distress obstructs smooth flow, the liver loses its harmonious nature, leading to rebellious liver qi. Symptoms like flank pain and alternating chills and fever are most commonly observed.
The Free and Easy Wanderer Decoction employs white peony root to nourish blood and nourish the liver, paired with bupleurum root to disperse and regulate liver excess. Clinically, we often combine these two herbs with cyperus rhizome, angelica sinensis root, curcuma rhizome, artemisia argyi, and citrus leaf to treat premenstrual breast distension, breast lobular hyperplasia, and milk stasis due to liver stagnation, all with remarkable efficacy.
Furthermore, in gynecology, red peony root is combined with rhubarb and heat-clearing agents to treat acute and chronic pelvic inflammatory disease; paired with white atractylodes to address metrorrhagia and menorrhagia caused by liver-spleen dysfunction; and combined with wolfberries to manage menopausal syndrome. Such applications are too numerous to list exhaustively.Peony root, with its ability to nourish blood, consolidate yin, tonify without causing greasiness, soften the liver, soothe the middle burner, relieve pain, and stop sweating, finds extensive application in TCM clinical practice, particularly in gynecology and obstetrics. It can be said that peony root is a common medication throughout a woman's life. Truly, it lives up to its reputation as the flower of gynecology and a trusted friend to women.
