Dang Gui (Angelica sinensis)

What is Dang Gui (Angelica sinensis)?

Dang Gui is the dried root of Angelica sinensis, a fragrant plant native to the mountain regions of China, Korea, and Japan. Known as the 'female ginseng,' it has been a cornerstone of Traditional Chinese Medicine for over two millennia and remains one of the most widely used herbal medicines in the world. It's treasured for its ability to nourish and move the blood — a concept in TCM that broadly covers circulation, hormonal health, and reproductive vitality.

How does Dang Gui (Angelica sinensis) work?

Dang Gui works through several pathways at once. Its key compound, Z-ligustilide, relaxes smooth muscle in the uterus, which helps ease cramping and regulate uterine contractions. Ferulic acid acts as a potent antioxidant and may help modulate inflammation and pain signals. The herb also appears to gently influence estrogen-related pathways — not by acting like estrogen itself, but by supporting the body's own hormonal signaling — which may explain its benefits for menopausal symptoms.

What forms does Dang Gui (Angelica sinensis) come in?

Traditional decoctions (boiling the whole root) remain common in TCM practice and are considered the most potent form. Standardized capsules and extracts offer convenience and consistent dosing. Tinctures absorb quickly and are easy to add to water or tea. For women using it alongside a practitioner, it is often combined with other herbs like Bai Shao (White Peony) or Chuan Xiong in classical formulas such as Si Wu Tang.

Where it comes from:

Dang Gui's use in Chinese medicine dates back at least 2,000 years, with its first formal documentation in the Shennong Bencao Jing (Divine Farmer's Classic of Materia Medica), one of the oldest Chinese herbal texts. It has historically been prescribed for virtually every major gynecological condition in TCM — from irregular periods to postpartum recovery — and its nickname 'female ginseng' reflects its revered status as a foundational tonic for women's health across East Asian medical traditions.

What does Dang Gui (Angelica sinensis) help with?

Dang Gui is the root of Angelica sinensis, a plant in the celery family. Chinese medicine has used it for more than 2,000 years. It is one of the best known women's health tonics in that tradition.

• Hot flashes and night sweats in menopause
  Early evidence — several human studies, all of multi-herb formulas that contained Dang Gui. Several studies of combination formulas with Dang Gui found fewer and milder hot flashes and night sweats. Other herbs sat in those formulas, so Dang Gui's own share of the change is unclear. The reports describe a gentle effect on estrogen-related signals, not a direct stand-in for estrogen.
  Evidence grade C · Traditional tier T3
• Periods that come at odd times
  Long traditional use · not yet tested in trials — some clinical work, mostly on traditional multi-herb formulas. Some clinical work has reported better cycle regularity. Most of that work used Dang Gui inside traditional formulas, not on its own. Chinese medicine has used it this way for centuries, linking odd cycles to poor blood flow or hormone shifts.
  Evidence grade D · Traditional tier T3
• Period pain and cramps
  Long traditional use · not yet tested in trials — lab work on womb muscle plus long traditional use; no human trial on file. Dang Gui is best known in tradition for painful periods. In lab work, its key compound relaxed the smooth muscle of the womb and raised blood flow to the pelvis. That may ease the heavy, achy feeling, but no human trial of this use is on file here.
  Evidence grade insufficient · Traditional tier T3
• PMS: bloating, cramping and low mood before a period
  Long traditional use · not yet tested in trials — traditional formula use plus lab work on muscle and blood flow. Chinese medicine uses Dang Gui for the mix of bloating, cramping and mood change before a period. It is nearly always one part of a formula, not a stand-alone remedy. The reasoning rests on lab findings about muscle relaxing and blood flow, not on human trials held here.
  Evidence grade insufficient · Traditional tier T3
• Poor circulation, cold hands and feet
  Long traditional use · not yet tested in trials — lab work on its coumarins and phthalides; user reports only. Dang Gui holds compounds called coumarins and phthalides. In lab work, these widened blood vessels and raised blood flow to the limbs. People who run cold often report more warmth with steady use, but that is not trial evidence.
  Evidence grade insufficient · Traditional tier T3
• Low energy and mild anemia ("blood deficiency")
  Long traditional use · not yet tested in trials — lab work on ferulic acid and polysaccharides, plus tradition. In Chinese medicine, Dang Gui is a main herb for what is called blood deficiency. That picture is tiredness, pale skin, dizziness and poor focus, and it overlaps with mild anemia. Lab work suggests ferulic acid and plant sugars may aid red cell making and iron handling.
  Evidence grade insufficient · Traditional tier T3
• Sore, stiff joints
  Long traditional use · not yet tested in trials — lab work on ferulic acid; use in classical pain formulas. Dang Gui appears in old Chinese formulas for pain, above all pain tied to poor blood flow. Lab work points to ferulic acid and other compounds that calm swelling. Human trials for mild joint pain are not on file here.
  Evidence grade insufficient · Traditional tier T3
• Fibroid pain and heavy bleeding, as support beside medical care
  Long traditional use · not yet tested in trials — traditional formula use only; no trial of the herb alone. TCM formulas for fibroids often include Dang Gui. The stated aim is to ease pain and heavy bleeding, not to shrink the fibroids. It is used beside standard medical care, and no trial of Dang Gui alone is on file.
  Evidence grade insufficient · Traditional tier T3
• Recovery after birth, once breastfeeding has ended
  Long traditional use · not yet tested in trials — centuries of traditional use; no human studies on file. Tonics used after birth have included Dang Gui for centuries. The traditional aim is to rebuild blood, restore energy and ease womb recovery. Safety during breastfeeding has not been established, so this use applies only after nursing has stopped.

What Dang Gui (Angelica sinensis) has not been shown to do

• It has not been shown to shrink uterine fibroids; the traditional role is easing pain and heavy bleeding.
• It has not been shown to work as a swap for estrogen therapy in menopause.
• The hot flash studies tested multi-herb formulas, so Dang Gui on its own has not been shown to cut hot flashes.
• It has not been shown to make periods regular on its own, apart from traditional formulas.
• No human study on file shows it raises iron levels or red blood cell counts, so it is not a stand-in for anemia care.
• It has not been shown to be safe while breastfeeding.

How to read this:

These grades describe the evidence, not the strength of the herb. A means steady trials in people. B means at least one good trial. C means small, mixed or early human studies. D means weak or clashing human results. Insufficient means no human study at all, only lab work, animal work or custom. This page sets out options and findings, not advice, and it is not a treatment plan. Talk with a clinician first, above all if you are pregnant, breastfeeding, taking blood thinners, or living with a hormone-sensitive condition.

What can Dang Gui (Angelica sinensis) help prevent?

• Recurrent menstrual cycle irregularity with consistent long-term use
• Oxidative stress-related cellular damage (via ferulic acid antioxidant activity)

Which foods are rich in Dang Gui (Angelica sinensis)?

1. Beets: Rich in nitrates and iron, beets support blood flow and red blood cell health — mirroring Dang Gui's core role as a blood-nourishing, circulation-enhancing herb.
2. Leafy greens (spinach, kale): High in iron, folate, and magnesium, leafy greens support the same blood-building and anti-fatigue effects central to Dang Gui's use for blood deficiency and low energy.
3. Black sesame seeds: Prized in TCM as a blood and yin tonic, black sesame seeds are often eaten alongside Dang Gui formulas to amplify nourishing effects and support hormonal balance.
4. Walnuts: A TCM 'blood-warming' food, walnuts provide omega-3s and phytosterols that support circulation and anti-inflammatory pathways similar to those Dang Gui targets.
5. Red dates (Jujube / Da Zao): One of the most common companion foods in TCM alongside Dang Gui, red dates tonify blood, reduce fatigue, and are traditionally prepared together in warming teas and soups.

What are the side effects of Dang Gui (Angelica sinensis)?

• Mild digestive upset, nausea, or bloating (especially on an empty stomach)
• Increased photosensitivity: skin may burn more easily in sunlight
• Heavy or altered menstrual flow in some women
• Mild headache or dizziness, particularly when starting
• Allergic reactions in people sensitive to plants in the Apiaceae/carrot family (celery, parsley, fennel)
• Contraindicated in pregnancy: may stimulate uterine contractions
• Not recommended during active heavy bleeding or hemorrhagic conditions
• Not established as safe during breastfeeding: avoid until more evidence exists

Good to know:

Dang Gui has a long history of safe use and is well-tolerated by most healthy adults when taken at recommended doses. It is not appropriate during pregnancy, and women with hormone-sensitive conditions should consult a doctor before use.

How much Dang Gui (Angelica sinensis) should you take?

• Recommended daily: Dried root decoction: 3–15 g per day (traditional TCM range). Standardized extract capsules: typically 500–1,000 mg, 2–3 times daily (follow product label). Tincture: 2–4 mL, 2–3 times daily. Doses vary significantly by form and whether used alone or in a combination formula.
• Best time of day: Traditionally taken in the morning and early afternoon. Avoid late evening if it causes any digestive stimulation.
• With or without food: Best taken with food or shortly after a meal to reduce the chance of nausea or digestive discomfort.
• Time to effect: Circulatory and cramping relief may begin within the first 1–2 cycles (2–4 weeks). Hormonal and menopausal symptom benefits typically require 6–12 weeks of consistent use.
• How long to take it: Safe for continuous use of 3–6 months when taken at standard doses. For menstrual regulation, many practitioners recommend cycling — taking it in the first half of the menstrual cycle and pausing during menstruation. Long-term use beyond 6 months should be guided by a qualified herbalist or integrative practitioner.
