Dang Gui (当归): The Queen of Herbs and Premier Blood Tonic

Dang Gui: The Queen of Herbs

Dang Gui (当归, Dāng Guī), also known as Angelica sinensis or Chinese Angelica, is arguably the most important blood-tonifying herb in Traditional Chinese Medicine. If Ginseng is the “King of Herbs” for Qi, then Dang Gui is undeniably the “Queen of Herbs” for Blood.

The name 当归 carries a poetic meaning — “shall return” — reflecting the ancient belief that this herb helps bring the body’s blood and vitality back to their proper state. It has been used in Chinese medicine for over 2,000 years and remains one of the most prescribed herbs today.

Properties and Channel Entry

Property	Description
Taste	Sweet, pungent (辛甘)
Temperature	Warm (温)
Channels entered	Heart, Liver, Spleen (归心、肝、脾经)
Category	Blood-tonifying herb (补血药)

The sweet taste nourishes and tonifies, while the pungent taste moves and invigorates. This combination gives Dang Gui its remarkable dual action.

Key Functions

1. Tonify Blood (补血)

Dang Gui is the premier blood tonic in the Chinese pharmacopoeia. It nourishes and builds blood, making it essential for all patterns of blood deficiency — from pale complexion and dizziness to numbness and menstrual irregularity.

2. Invigorate Blood (活血)

Unlike most tonifying herbs that are purely nourishing, Dang Gui also actively moves blood. This makes it invaluable for conditions where blood is both deficient and stagnant — a common combination in clinical practice.

3. Regulate Menstruation (调经)

Dang Gui’s dual blood-tonifying and blood-invigorating actions make it the most important herb for menstrual disorders. It can both build blood when it’s deficient and move blood when it’s stagnant, addressing the root of most menstrual issues.

4. Moisten the Intestines (润肠通便)

Blood deficiency often leads to intestinal dryness and constipation, especially in the elderly and postpartum women. Dang Gui’s moistening nature addresses this by providing fluid through the blood.

The Unique Dual Action

What makes Dang Gui truly special among blood herbs is its ability to both tonify and invigorate blood simultaneously. Most herbs do one or the other:

Herb	Tonifies Blood	Invigorates Blood
Dang Gui	Yes	Yes
Shu Di Huang (熟地黄)	Yes (strongly)	No
Chuan Xiong (川芎)	No	Yes (strongly)
Bai Shao (白芍)	Yes	No

This dual action explains why Dang Gui appears in more formulas than any other blood herb — it addresses both the deficiency and the stagnation that often coexist.

Head, Body, and Tail: Different Parts, Different Actions

TCM traditionally distinguishes three parts of the Dang Gui root, each with a different emphasis:

Part	Chinese Name	Primary Action	Clinical Use
Head	当归头	Tonifies blood	Blood deficiency with no stagnation
Body	当归身	Tonifies blood (moderate)	General blood deficiency
Tail	当归尾	Invigorates blood	Blood stasis and pain
Whole	全当归	Tonifies + Invigorates	Blood deficiency with mild stagnation

This nuanced usage demonstrates the sophistication of TCM herbal practice — the same plant can be directed toward different therapeutic goals depending on which part is selected.

Clinical Applications

Menstrual Disorders

Dang Gui is considered the most essential herb for women’s health in TCM:

Amenorrhea (absent periods) — tonifies blood to restore flow
Dysmenorrhea (painful periods) — invigorates blood to relieve pain
Irregular menstruation — regulates by both nourishing and moving
Scanty periods — builds blood volume
Menorrhagia (heavy periods) — when combined with astringent herbs

Anemia and Blood Deficiency

Signs of blood deficiency that Dang Gui addresses:

Pale or sallow complexion
Dizziness and lightheadedness
Blurred vision and dry eyes
Numbness or tingling in extremities
Pale lips and nails
Insomnia (Heart blood deficiency)

Postpartum Recovery

After childbirth, women lose significant blood. Dang Gui is a cornerstone of postpartum care in TCM, helping to:

Rebuild blood volume
Promote lochia discharge
Relieve postpartum abdominal pain
Restore energy and vitality

Abdominal Pain

Dang Gui treats abdominal pain caused by blood stasis or blood deficiency, particularly:

Cold-induced abdominal pain
Pain that is fixed and stabbing (blood stasis)
Pain improved by warmth and pressure (blood deficiency)

Constipation from Blood Deficiency

Especially common in:

Elderly patients
Postpartum women
Chronic illness with blood depletion
After major surgery

Famous Formulas Containing Dang Gui

Si Wu Tang (四物汤) — Four Substance Decoction

The foundation of all blood-tonifying formulas, composed of:

Shu Di Huang — strongly tonifies blood
Bai Shao — nourishes blood, softens the Liver
Dang Gui — tonifies and invigorates blood
Chuan Xiong — invigorates blood, moves Qi

This formula from the Song Dynasty is considered the “mother of all blood formulas” and is the basis for dozens of derived prescriptions.

Dang Gui Bu Xue Tang (当归补血汤)

A remarkably simple yet powerful two-herb formula:

Huang Qi (Astragalus) — 5 parts
Dang Gui — 1 part

Based on the principle that “Qi is the commander of Blood” — by strongly tonifying Qi, blood production is stimulated. Used for blood deficiency with fever or sweating.

Gui Pi Tang (归脾汤)

“Tang that returns to the Spleen” — tonifies both Spleen Qi and Heart Blood. Used for insomnia, anxiety, poor memory, and fatigue from overthinking. Contains Dang Gui along with Qi tonics and calming herbs.

Dang Gui vs. Ginseng: Queen of Blood and King of Qi

Raw (生当归)	Dried, unprocessed	Invigorate blood, moisten intestines
Wine-fried (酒当归)	Stir-fried with rice wine	Enhances blood-invigorating action
