Di Ding Dang Gui Tang: Benefits, Uses, and How to Make It

Introduction to Herbal Soups

Zihuadiding Danggui Tang (Viola yedoensis and Angelica sinensis Soup) is a classic formula originating from traditional Chinese medicine dietary therapy. Combining Viola yedoensis (Zihuadiding) and Angelica sinensis (Danggui) as core ingredients, with a small amount of seasoning, this preparation, based on the principle of medicine and food sharing the same source, helps maintain comfort during occasional imbalances related to blood heat and stasis or accumulation of internal toxins.Viola yedoensis is cold in nature, with bitter and pungent taste. Traditionally, it has been used to help maintain a balanced internal environment, promote comfort, support normal blood function, and assist with occasional swelling.

Angelica sinensis is warm in nature, with sweet and pungent taste. It is a commonly used food ingredient that supports blood nourishment, promotes healthy blood circulation, helps maintain normal menstrual regularity, and provides comfort for occasional discomfort.

Together, the cold and warm natures, along with the clearing and nourishing actions, harmonize to support a balanced state of cleansing and replenishment.

This soup has long been passed down in folk tradition and is especially suitable for women who experience occasional menstrual cycle irregularities or discomfort due to Blood Heat accompanied by Stasis, as well as for individuals dealing with initial localized skin issues such as redness, swelling, heat, and discomfort arising from internal heat accumulation. It is simple to prepare, with a mild and slightly sweet flavor, and can be enjoyed as a daily health-supporting soup or used under professional guidance to help maintain general well-being. Modern research has found that Viola yedoensis (Zihuadiding) contains flavonoids and coumarins, which exhibit broad-spectrum antibacterial and soothing properties; Angelica sinensis (Danggui) contains ferulic acid and volatile oils that help support microcirculation and immune regulation. The synergistic action of these two ingredients allows the soup to clear heat without impairing vital Qi, and to nourish the blood without retaining pathogenic factors, thus promoting a balanced internal environment.

Health benefits

The core function of Zi Hua Di Ding Dang Gui Tang (Viola yedoensis and Angelica sinensis Decoction) is to support the body’s natural cooling processes, helps with occasional, promote healthy blood circulation, and help with occasional swelling. Zi Hua Di Ding (Viola yedoensis) is particularly adept at supporting the body’s ability to maintain a cool and balanced condition in the blood aspect, helping to helps with occasional redness, occasional swelling, heat, and discomfort associated with temporary heat accumulation, as well as local skin discomfort. When combined with Dang Gui (Angelica sinensis), it enhances the ability to support healthy blood circulation and reduce stagnation, providing an outlet for temporary heat, while Dang Gui’s warming nature moderates the cool nature of Zi Hua Di Ding to help maintain normal Spleen and stomach function over time.

On the other hand, this formula also helps maintain regular menstrual cycles and period comfort. For conditions such as early menstruation, dark and clotted menstrual blood, and stabbing lower abdominal pain during menstruation—which may arise from blood heat with stagnation—the combination of *Viola yedoensis* (Zihuadiding) and *Angelica sinensis* (Danggui) can help clear heat without retaining blood, and promote blood circulation without aggravating heat, thus assisting in clearing heat and resolving stasis to support normal menstrual flow. Furthermore, this decoction also helps helps with occasional discomfort such as thick yellow leukorrhea and scanty dark urine caused by damp-heat descending to the lower burner, reflecting the TCM principle of “supports different wellness with the same method” (Yi Bing Tong Zhi).

Recommended Usage Scenarios

This formula is primarily indicated for TCM patterns such as “Heat Toxin and Stasis” or “Blood Heat with Stasis.” It is commonly associated with facial skin discomfort accompanied by redness, swelling, and pustules; early localized breast swelling; and temporary skin irritations involving follicular and minor localized reactions. It is also used to support women’s health when occasional pelvic discomfort and changes in vaginal discharge are present.

Properties of Food Ingredients

From the perspective of nature, flavor, and meridian tropism, *Viola yedoensis* (Zihuadiding) has a bitter and pungent taste, cold nature, and enters the Heart and Liver Meridians. Bitter taste can clear and drain, as well as dry dampness; pungent taste can dissipate masses and unblock collaterals; cold nature can clear and resolve heat-toxicity. Therefore, it supports clearing heat from the Heart and Liver Meridians, helping maintain a balanced internal environment during times of excessive internal heat. *Angelica sinensis* (Danggui) has a sweet and pungent taste, warm nature, and enters the Liver, Heart, and Spleen Meridians. Sweet taste can tonify and helps with occasional tension; pungent taste can promote movement and invigorate blood; warm nature can facilitate the flow of blood vessels. It is regarded as the “Qi-moving herb within the blood realm,” supporting both nourishing and invigorating blood flow, thereby promoting healthy blood circulation. When used together, *Viola yedoensis* (Zihuadiding) clears heat to help reduce the source of heat-related factors, while *Angelica sinensis* (Danggui) invigorates blood to help disperse stagnation, complementing each other’s functions.

Specifically, the flavonoids found in Viola yedoensis (Zi Hua Di Ding) possess notable soothing and antioxidant properties that support the body’s natural defense mechanisms against common bacteria such as Staphylococcus aureus. The ferulic acid in Angelica sinensis (Dang Gui) helps maintain healthy platelet activity, supports smooth blood circulation, and promotes oxygen supply to areas of local inflammation. When used together, these two herbs combine the dual actions of clearing heat and soothing tissues, as well as promoting blood circulation to remove stasis—thereby addressing the underlying pattern of “Heat accumulation with Blood Stasis,” a key principle in traditional Chinese medicine for managing abscesses, ulcers, and Heat-related blood conditions. In addition, Angelica sinensis nourishes the Yin and Blood that may be depleted by Heat, helping to expel pathogenic factors without compromising the body’s healthy Qi (vital energy).

Suitable Population

This soup is especially suitable for individuals with a constitution characterized by internal heat and toxin abundance, as well as sluggish blood circulation. Common manifestations include recurring red, swollen, and painful pimples or folliculitis on the face or back, or the sudden appearance of red, hard, hot, and tender nodules in localized areas of the body. It may also serve as a supportive dietary option for women experiencing Blood-Heat constitution accompanied by a tendency toward earlier menstrual cycles, increased menstrual flow, dark menstrual blood, lower abdominal discomfort during menstruation, premenstrual breast distension, as well as acute flare-ups of chronic pelvic discomfort with yellow vaginal discharge and a bearing-down sensation in the lower abdomen.

Additionally, for adolescents or young adults with a constitution prone to internal heat (e.g., dry stools, dark yellow urine), when experiencing mild skin discomfort or occasional feminine imbalance, this may be used according to pattern differentiation. For individuals under long-term work stress or who favor spicy, greasy foods leading to accumulated internal heat, taking 2–3 times per month is a suitable choice to support a balanced internal environment and promote general well-being.

Cautions

Individuals with a Spleen and Stomach Deficiency Cold constitution should use with caution or avoid. Those who typically experience occasional cold sensations and discomfort in the stomach, loose stools, poor appetite, tastelessness in the mouth, aversion to cold, and cold extremities may find that consuming cooling herbs such as Viola yedoensis (Zihuadiding) could exacerbate these tendencies, potentially leading to temporary digestive upset or further discomfort. Pregnant women should use under the guidance of a qualified professional, as Angelica sinensis (Danggui) may influence uterine muscle activity, and Viola yedoensis (Zihuadiding) is cooling in nature, which may not support optimal maternal health during pregnancy.

In addition, individuals with extreme Qi and Blood deficiency and without heat signs (such as pale complexion, shortness of breath and reluctance to speak, dizziness and palpitations, pale tongue and weak pulse) should not use this formula alone, as its strong heat-clearing properties may further deplete Yang Qi. This formula is contraindicated in those allergic to ingredients such as Viola yedoensis (Zihuadiding) or Angelica sinensis (Danggui). Women with heavy menstrual bleeding should use caution during their menstrual period, as Danggui’s blood circulation-supporting properties may increase menstrual flow. Those taking anticoagulant medications (e.g., warfarin) should consult a professional before use to avoid potential interactions.

Ingredient ratio of the formula

The standard single-serving formula for Zihuadiding Danggui Tang (Viola yedoensis and Angelica sinensis Decoction) is as follows:

• Viola yedoensis (Chinese Violet, dried): 15 g
• Angelica sinensis (Danggui) (whole root or body): 10 g
• Ziziphus jujuba (Hongzao, pitted): 3 pieces (approx. 10 g)
• Zingiber officinale (Shengjiang): 3 slices (approx. 5 g)
• Purified water: 800 ml
• Salt or honey: in moderation (for seasoning only, not for medicinal use)

If used for acute localized redness, swelling, heat, and pain with pronounced internal heat, the amount of Viola yedoensis (Zihuading) may be increased to 18 grams; if signs of blood deficiency are evident or to support regular menstrual cycles, Angelica sinensis (Dang Gui) may be increased to 12 grams. It is recommended to start with the standard formula and consult a TCM practitioner to adjust the dosage based on individual constitution.

Preparation Method

Step 1: Rinse Viola yedoensis (Zihuadiding) and Angelica sinensis (Danggui) quickly with clean water to remove surface dust. Clean the red dates (Hongzao) and tear or cut them open to allow the release of active constituents. Clean the ginger (Shengjiang) and slice it.

Step 2: Take a clay pot or stainless steel pot (avoid iron or aluminum pots to helps maintain ingredients from reacting with metal). Add 800 ml of purified water, then add Viola yedoensis (Zi Hua Di Ding), Angelica sinensis (Dang Gui), red dates (Hong Zao), and fresh ginger slices. Soak for 20 minutes to allow the ingredients to fully absorb water.

Step 3: Place the pot over high heat until it reaches a boil, then reduce to low heat and maintain a gentle simmer for 30 minutes. During this time, do not open the lid frequently to helps maintain the loss of aromatic components.

Step 4: After boiling, strain the solid residues using a fine mesh sieve or gauze, collecting approximately 300–400 ml of liquid. At this point, the decoction can be flavored according to personal preference: add a pinch of salt (to make a savory soup), or, after allowing the liquid to cool slightly (below 60°C/140°F), add an appropriate amount of honey (honey is sensitive to high temperatures, so wait until the temperature drops before adding). Stir well and then consume.

Recommended Usage

It is recommended to take it once daily, warmed, on an empty or half-empty stomach. The duration of continuous use should not exceed seven days. For acute discomfort, it may be taken twice daily, once in the morning and once in the evening, with at least six hours between doses. Discontinue use once the condition has resolved. Long-term continuous use is not recommended, as its cooling and draining nature may affect the stomach.

2. During consumption, avoid spicy, greasy, raw and cold foods, as well as seafood ‘hair’ foods (fa wu), such as chili, lamb, crab, and chives. These may interfere with the effects of the ingredients or aggravate Damp-Heat. At the same time, it is recommended to drink plenty of warm water to support metabolism and waste elimination.

3. If there is no improvement in signs of imbalance after three days, or if adverse reactions such as stomach discomfort, diarrhea, or skin rash occur, please discontinue use and consult a qualified professional. This soup is a medicinal dietary supplement and is not a substitute for standard medical supports. For conditions involving systemic signs of imbalance such as fever or swollen lymph nodes—particularly those associated with suppurative processes—please seek prompt medical attention.
