Huang Qi Gui Zhi Wu Wu Tang

Astragalus and Cinnamon Twig Five-Substance Decoction · 黃芪桂枝五物湯

Also known as: Huang Qi Wu Wu Tang (黄芪五物汤), Gui Zhi Wu Wu Tang (桂枝五物汤), Wu Wu Tang (五物汤),

A classical formula used to improve circulation and relieve numbness, tingling, or weakness in the limbs caused by Qi deficiency and sluggish blood flow. It is especially suited for people who are prone to sweating, tire easily, and experience worsening symptoms in cold or windy conditions. Modern practitioners commonly apply it for peripheral neuropathy, post-stroke numbness, and Raynaud's phenomenon.

Patterns Addressed

In TCM, symptoms don't appear randomly — they cluster into recognizable patterns of disharmony that reveal what's out of balance in the body. Huang Qi Gui Zhi Wu Wu Tang is designed to correct these specific patterns.

Why Huang Qi Gui Zhi Wu Wu Tang addresses this pattern

Blood Obstruction (Xue Bi, 血痹) is a specific pattern where Qi deficiency leads to sluggish Blood circulation, and mild Wind-Cold pathogenic factors lodge in the blood vessels of the skin and flesh, causing numbness and loss of sensation. Unlike painful obstruction (Feng Bi), Blood Obstruction primarily manifests as numbness rather than pain. Huang Qi Gui Zhi Wu Wu Tang addresses this by tonifying Qi with Huang Qi to restore the driving force behind Blood circulation, warming and opening the channels with Gui Zhi and Sheng Jiang to disperse the lodged Wind-Cold, and nourishing Blood with Shao Yao to restore proper nutrition to the skin and muscles. The formula simultaneously treats both root (Qi deficiency) and branch (Blood stagnation with mild Wind-Cold).

A practitioner would look for one or more of these signs

Skin Numbness

Numbness or loss of sensation in the limbs or skin, the hallmark symptom

Tingling

Tingling or 'pins and needles' sensation in the extremities

Eye Fatigue

General fatigue and weakness, worse with exertion

Excessive Sweating

Spontaneous sweating, especially on exertion

Cold Extremities

Cold hands and feet due to impaired Yang circulation

Aversion To Cold

Sensitivity to wind and cold drafts

Commonly Prescribed For

These conditions can arise from the patterns above. A practitioner would consider Huang Qi Gui Zhi Wu Wu Tang when these conditions are specifically caused by those patterns — not for all cases of these conditions.

TCM Interpretation

In TCM, diabetic peripheral neuropathy falls under the category of Blood Obstruction (Xue Bi). The condition arises when long-standing Qi and Yin deficiency (often associated with the 'wasting-thirst' disease pattern of diabetes) leads to poor Blood circulation in the limbs. When Qi is too weak to push Blood through the fine vessels of the hands and feet, these areas lose their nourishment and sensation declines. The numbness, tingling, and loss of feeling characteristic of diabetic neuropathy closely match the classical description of Blood Obstruction: the body feels 'not like one's own' and sensation is dulled or absent.

Why Huang Qi Gui Zhi Wu Wu Tang Helps

Huang Qi Gui Zhi Wu Wu Tang directly targets the core TCM mechanism of diabetic peripheral neuropathy by simultaneously boosting Qi and restoring Blood flow to the extremities. Huang Qi tonifies the Qi needed to drive Blood circulation and has been shown in modern research to improve microcirculation and nerve conduction velocity. Gui Zhi warms and opens the channels, helping Blood reach the peripheral nerves. Shao Yao nourishes the Blood to restore proper nutrition to nerve tissue. The heavy dose of Sheng Jiang propels the formula's action outward to the hands and feet where symptoms concentrate. Meta-analyses of randomized controlled trials have found that this formula, often with modifications, outperforms conventional treatments like mecobalamin for improving both symptoms and nerve conduction velocities in diabetic neuropathy.

How It Addresses the Root Cause

TCM doesn't just suppress symptoms — it aims to resolve the underlying imbalance. Here's how Huang Qi Gui Zhi Wu Wu Tang works at the root level.

This formula addresses a condition the Jin Gui Yao Lue calls Blood Bi (血痹, "blood obstruction"). The underlying disease logic begins with a person who is constitutionally deficient in Qi and Blood. Because Qi is weak, the body's defensive layer (Wei Qi) is not vigorous enough to keep pathogenic influences out. At the same time, the nutritive aspect (Ying Qi) that nourishes the blood vessels is also insufficient, so blood circulation becomes sluggish.

In this vulnerable state, even mild wind exposure — especially after physical exertion or sweating — can slip past the weakened defenses and lodge in the blood vessels and muscle layers. This external wind, combined with the pre-existing poor blood flow, causes the blood to congeal and stagnate in the peripheral channels. The result is numbness, tingling, and loss of sensation in the skin and limbs, sometimes with dull pain in fixed locations. The person's Yang Qi cannot reach the extremities, so the limbs may feel cold and heavy. The characteristic pulse is faint at the superficial positions (reflecting Qi weakness) and slightly tight at the deep position (reflecting the congealed blood). Unlike true Wind Bi (which involves strong pain that migrates from joint to joint), Blood Bi presents mainly as sensory loss and numbness, because the core problem is not rampant wind but rather insufficient Qi failing to push blood through the vessels.

The formula corrects this by simultaneously boosting Qi to restore the body's motive force and gently warming the channels to disperse the stagnation. Once Qi is strong enough to drive blood circulation and the mild wind is expelled, sensation and nourishment return to the affected tissues.

Formula Properties

Every formula has an inherent temperature, taste, and affinity for specific organs — these properties determine how it interacts with the body

Overall Temperature

Warm

Taste Profile

Predominantly sweet and pungent — sweet (Huang Qi, Da Zao, Bai Shao) to tonify Qi and nourish Blood, pungent (Gui Zhi, Sheng Jiang) to warm the channels and disperse stagnation.

King — Main ingredient driving the formula
Deputy — Assists and enhances the King
Assistant — Supports or moderates other herbs
King — Main ingredient driving the formula
Huang Qi

Huang Qi

Astragalus root

Dosage 9 - 30g
Temperature Slightly Warm
Taste Sweet (甘 gān)
Organ Affinity Spleen, Lungs

Role in Huang Qi Gui Zhi Wu Wu Tang

The chief herb of the formula, Huang Qi is sweet and warm. It powerfully tonifies Qi, strengthens the body's defensive (Wei) Qi at the surface, and drives the movement of Qi and Blood through the channels. By bolstering Qi, it addresses the root deficiency that allows pathogenic Wind to lodge in the blood vessels and cause numbness.
Deputies — Assists and enhances the King
Gui Zhi

Gui Zhi

Cinnamon twig

Dosage 9 - 15g
Temperature Warm
Taste Acrid / Pungent (辛 xīn), Sweet (甘 gān)
Organ Affinity Heart, Lungs, Urinary Bladder

Role in Huang Qi Gui Zhi Wu Wu Tang

Gui Zhi is acrid and warm. It warms and opens the channels, disperses Wind-Cold, and promotes Yang Qi circulation through the limbs. When paired with Huang Qi, the two reinforce each other: Gui Zhi helps Huang Qi reach the surface and extremities, while Huang Qi ensures that Gui Zhi's dispersing action does not weaken the body's defenses.
Bai Shao

Bai Shao

White peony root

Dosage 9 - 15g
Temperature Slightly Cool
Taste Bitter (苦 kǔ), Sour (酸 suān)
Organ Affinity Liver, Spleen

Role in Huang Qi Gui Zhi Wu Wu Tang

Shao Yao nourishes the Blood and harmonizes the nutritive (Ying) layer. Paired with Gui Zhi, it balances Yin and Yang and regulates the interplay between the body's nutritive and defensive systems. It also softens and relaxes the blood vessels, helping to relieve the stiffness and impaired sensation caused by Blood stagnation.
Assistants — Supports or moderates other herbs
Sheng Jiang

Sheng Jiang

Fresh ginger rhizome

Dosage 15 - 30g
Temperature Slightly Warm
Taste Acrid / Pungent (辛 xīn)
Organ Affinity Lungs, Spleen, Stomach

Role in Huang Qi Gui Zhi Wu Wu Tang

Used at double the dosage of the other main herbs in the original formula, Sheng Jiang is acrid and warm. It strongly disperses Wind-Cold from the surface and carries the power of Huang Qi and Gui Zhi outward to the skin and extremities. Its large dose is key to the formula's effectiveness: it propels the other herbs to the body surface where the obstruction resides.
Da Zao

Da Zao

Chinese date (Jujube fruit)

Dosage 4 - 12 pieces
Temperature Warm
Taste Sweet (甘 gān)
Organ Affinity Spleen, Stomach, Heart

Role in Huang Qi Gui Zhi Wu Wu Tang

Da Zao is sweet and warm. It nourishes the Blood and Qi, supports the Spleen and Stomach to strengthen the source of Qi and Blood production, and harmonizes all the other herbs. Paired with Sheng Jiang, it helps regulate the nutritive and defensive systems together.

Why This Combination Works

How the herbs in Huang Qi Gui Zhi Wu Wu Tang complement each other

Overall strategy

The formula targets Blood Obstruction (Xue Bi) arising from underlying Qi deficiency and impaired circulation of the nutritive and defensive systems. The prescription strategy is to powerfully boost Qi while simultaneously warming and opening the channels, so that Blood can flow freely and numbness resolves. As later commentators noted, this is essentially Gui Zhi Tang (Cinnamon Twig Decoction) with Zhi Gan Cao removed and Huang Qi added, shifting the formula's focus from harmonizing the surface toward actively driving Yang Qi outward to overcome obstruction.

King herb

Huang Qi serves as the King because the root cause of Blood Obstruction is Qi deficiency. When Qi is too weak to propel Blood through the vessels, stagnation develops and numbness results. Huang Qi's sweet, warm nature directly tonifies the defensive Qi at the body's surface and gives the formula the driving force needed to push through the obstruction. Its strong, upward-and-outward moving quality makes it ideal for conditions affecting the skin and limbs.

Deputy herbs

Gui Zhi warms the channels and unblocks Yang Qi, directly addressing the Cold obstruction in the blood vessels. Together with Huang Qi, it creates a powerful Qi-boosting and channel-warming partnership: Gui Zhi enables Huang Qi's tonifying power to reach the extremities, while Huang Qi prevents Gui Zhi from over-dispersing and weakening the body. Shao Yao nourishes Blood and harmonizes the nutritive layer, pairing with Gui Zhi to regulate the Ying-Wei (nutritive-defensive) balance and ensure the formula does not only push outward but also nourishes the blood vessels from within.

Assistant herbs

Sheng Jiang (reinforcing assistant) is used at double dose in the original formula. It amplifies Gui Zhi's dispersing and warming action, carrying the formula's therapeutic power outward to the skin and flesh where the obstruction lodges. Da Zao (reinforcing assistant) nourishes Qi and Blood to support Huang Qi and Shao Yao's tonifying functions, and strengthens the Spleen as the source of new Qi and Blood production.

Notable synergies

The Huang Qi plus Gui Zhi pairing is the formula's signature combination: Qi tonification plus Yang warming creates a synergy where the body's own Qi is strong enough to push pathogenic factors out of the blood vessels. The Gui Zhi plus Shao Yao pairing harmonizes Ying and Wei, inherited from Gui Zhi Tang, ensuring that the defensive and nutritive systems work in concert. The removal of Gan Cao (licorice) from the Gui Zhi Tang base is itself strategically significant: Gan Cao's moderating, retaining quality would slow the formula's outward-moving momentum, which is precisely what this formula needs to reach the body surface.

How to Prepare

Traditional preparation instructions for Huang Qi Gui Zhi Wu Wu Tang

The original text instructs: combine the five ingredients with approximately 1,200 mL of water. Bring to a boil, then simmer until reduced to approximately 400 mL. Strain and divide into three portions. Take each portion warm, three times daily.

In modern practice: soak the herbs in water for 30 minutes before cooking. Bring to a boil over high heat, then reduce to low heat and decoct for 20 to 30 minutes. The decoction is typically divided into two servings taken warm, morning and evening. Fresh Sheng Jiang (ginger) should be sliced thickly before adding.

Common Modifications

Contraindications

Situations where Huang Qi Gui Zhi Wu Wu Tang should not be used or requires extra caution

Caution

Yin deficiency with Heat signs (e.g. night sweats, hot flashes, red tongue with scanty coating). This warming, Yang-promoting formula can worsen Yin-deficient Heat.

Caution

Excess Heat or active inflammatory conditions with redness, swelling, and heat. The warm nature of Gui Zhi and Sheng Jiang can aggravate excess Heat patterns.

Caution

Wind-Cold-Damp Bi syndrome (true Wind Bi) with strong exterior pathogenic factors and no underlying Qi deficiency. Blood Bi (which this formula treats) and Wind Bi have different pathomechanisms and require different strategies.

Caution

Patients with significant bleeding disorders or those on high-dose anticoagulant therapy, as the formula promotes blood circulation. Use with caution and clinical monitoring.

Special Populations

Important considerations for pregnancy, breastfeeding, and pediatric use

Pregnancy

Generally considered safe for use during pregnancy, as none of the five herbs (Huang Qi, Gui Zhi, Bai Shao, Sheng Jiang, Da Zao) are classified as pregnancy-prohibited or pregnancy-cautious substances in standard TCM pharmacopoeias. Gui Zhi is warm and mildly activating but is used at moderate dosage in this formula and is well-balanced by Bai Shao. However, as with any herbal formula during pregnancy, use should be supervised by a qualified practitioner who can adjust the dosage appropriately. The heavy dose of Sheng Jiang (fresh ginger) in the original prescription may warrant reduction in pregnancy to avoid excessive dispersing action.

Breastfeeding

No specific concerns have been identified for breastfeeding. All five herbs in the formula (Huang Qi, Gui Zhi, Bai Shao, Sheng Jiang, Da Zao) are common food-grade or mild medicinal substances with a long history of safe use. Huang Qi is traditionally used postpartum to support Qi recovery. No adverse effects on lactation or infant health have been reported in the literature. Standard clinical precautions apply: use under practitioner guidance and monitor for any changes in the infant.

Children

This formula can be used in children with appropriate dosage reduction based on age and weight. General guidelines: children under 5 years should receive approximately one-quarter to one-third of the adult dose; children ages 5-10 may receive one-third to one-half; adolescents may take two-thirds to the full adult dose. The formula's ingredients are all mild and food-grade in nature, making it relatively well-tolerated in pediatric populations. However, the large dose of Sheng Jiang (fresh ginger) in the classical prescription may be too pungent for very young children and should be reduced. As always, pediatric use should be supervised by a qualified practitioner.

Drug Interactions

If you are taking pharmaceutical medications, be aware of these potential interactions with Huang Qi Gui Zhi Wu Wu Tang

Anticoagulants and antiplatelet agents (e.g. warfarin, heparin, aspirin, clopidogrel): Gui Zhi (cinnamon twig) and Bai Shao (white peony root) have mild blood-activating properties. Concurrent use may theoretically enhance anticoagulant effects, potentially increasing bleeding risk. Clinical monitoring of coagulation parameters is advisable.

Hypoglycemic medications (e.g. metformin, insulin): Huang Qi (astragalus) has documented hypoglycemic effects. When this formula is used for diabetic peripheral neuropathy alongside glucose-lowering drugs, blood sugar should be monitored more closely, as additive hypoglycemic effects are possible.

Immunosuppressants (e.g. cyclosporine, tacrolimus): Huang Qi has well-documented immunomodulatory properties and can stimulate immune function. This may theoretically counteract the effect of immunosuppressive drugs. Caution and clinical supervision are warranted in transplant patients or those on immunosuppressive therapy.

Usage Guidance

Practical advice for getting the most out of Huang Qi Gui Zhi Wu Wu Tang

Best time to take

Warm, 30 minutes after meals, two to three times daily. Classical instructions specify taking approximately 200ml warm per dose, three times daily.

Typical duration

Chronic conditions: typically 4-12 weeks, reassessed regularly by a practitioner. May be taken for longer periods with modifications for chronic neuropathy.

Dietary advice

While taking this formula, favour warm, cooked, easily digestible foods that support Qi and Blood, such as congee, soups, warm grains, dates, and lightly cooked vegetables. Avoid cold and raw foods (salads, iced drinks, raw fish), greasy or heavy foods, and excessive dairy, as these can impair Spleen function and counteract the warming, Qi-tonifying action of the formula. The Jin Gui Yao Lue advises against cold exposure during treatment. Light physical activity is encouraged to promote Qi and blood circulation, but overexertion and heavy sweating should be avoided, as these deplete the Qi this formula is designed to restore.

Huang Qi Gui Zhi Wu Wu Tang originates from Jin Gui Yao Lue (金匮要略, Essential Prescriptions of the Golden Chamber) by Zhang Zhongjing Eastern Hàn dynasty, ~200 CE

Classical Texts

Key passages from the classical Chinese medical texts that first described Huang Qi Gui Zhi Wu Wu Tang and its clinical use

Jin Gui Yao Lue (《金匮要略》), Chapter 6, Blood Bi and Consumptive Disease:

「血痹阴阳俱微,寸口关上微,尺中小紧,外证身体不仁,如风痹状,黄芪桂枝五物汤主之。」

"When Blood Bi shows both Yin and Yang as faint, the pulse at the wrist [cun kou] and the guan position is faint, and the chi position is slightly tight, the external signs are numbness of the body resembling Wind Bi — Huang Qi Gui Zhi Wu Wu Tang governs this."


Jin Gui Yao Lue Lun Zhu (《金匮要略论注》) by Xu Bin (徐彬), Ming Dynasty:

「此由全体风湿血相搏,痹其阳气,使之不仁。故以桂枝壮气行阳,芍药和阴,姜、枣以和上焦荣卫,协力驱风……此即桂枝汤去草加芪也,立法之意,重在引阳,故嫌甘草之缓小,若黄芪之强有力耳。」

"This arises from wind, dampness, and blood mutually contending throughout the body, obstructing the Yang Qi and causing numbness. Therefore Gui Zhi strengthens Qi and promotes Yang, Shao Yao harmonises the Yin, and Jiang and Zao harmonise the upper burner's nutritive and defensive Qi, working together to dispel wind… This is simply Gui Zhi Tang with Gan Cao removed and Huang Qi added. The intent of the prescription focuses on leading Yang. Gan Cao was considered too mild and slow, whereas Huang Qi is strong and powerful."


Jin Gui Fang Ge Kuo (《金匮方歌括》) by Chen Nianzu (陈念祖), Qing Dynasty:

「此即桂枝汤去甘草之缓,加黄芪之强有力者,于气分中调其血,更妙倍用生姜以宣发其气,气行则血不滞而痹除。」

"This is Gui Zhi Tang with the mild Gan Cao removed and the strong Huang Qi added. It regulates the Blood within the Qi aspect. The brilliant doubling of Sheng Jiang further disseminates Qi — when Qi moves, Blood does not stagnate and the obstruction is resolved."

Historical Context

How Huang Qi Gui Zhi Wu Wu Tang evolved over the centuries — its origins, lineage, and place in the broader tradition of Chinese medicine

Huang Qi Gui Zhi Wu Wu Tang ("Astragalus and Cinnamon Twig Five-Substance Decoction") was created by Zhang Zhongjing (张仲景) in the Eastern Han Dynasty (circa 200 CE) and recorded in his Jin Gui Yao Lue (Synopsis of Prescriptions of the Golden Chamber), Chapter 6 on Blood Bi and Consumptive Disease. The formula is structurally a modification of the famous Gui Zhi Tang (Cinnamon Twig Decoction), with two key changes: Gan Cao (licorice) is removed and Huang Qi (astragalus) is added, while the dose of Sheng Jiang (fresh ginger) is doubled. Ming Dynasty commentator Xu Bin explained that Gan Cao was considered "too mild and slow" for the task of leading Yang Qi outward, whereas Huang Qi provides a "strong and powerful" upward and outward force. The doubling of Sheng Jiang further strengthens the formula's dispersing action to reach the exterior.

Throughout history, the formula has also been known by several aliases, including Huang Qi Wu Wu Tang (《三因极一病证方论》), Gui Zhi Wu Wu Tang (《赤水玄珠》), and simply Wu Wu Tang (《东医宝鉴》). In modern clinical practice, the formula's scope has expanded dramatically beyond its original Blood Bi indication. It is now widely used for conditions involving numbness, poor peripheral circulation, and nerve dysfunction, including diabetic peripheral neuropathy, post-stroke sequelae, cervical spondylosis, Raynaud's phenomenon, carpal tunnel syndrome, and chemotherapy-induced peripheral neuropathy. This broad modern application reflects the enduring clinical insight that Qi deficiency with blood stasis in the peripheral vessels underlies many conditions Western medicine classifies separately.

Modern Research

4 published studies investigating the pharmacological effects or clinical outcomes of Huang Qi Gui Zhi Wu Wu Tang

1

Meta-analysis of 16 RCTs on HGWWD for Diabetic Peripheral Neuropathy (2016)

Pang B, Zhao TY, Zhao LH, Wan F, Ye R, Zhou Q, Tian F, Tong XL. Neural Regeneration Research, 2016, 11(8): 1347-1358.

This meta-analysis pooled data from 16 randomized controlled trials to assess the formula's effectiveness for diabetic peripheral neuropathy. Treatment groups receiving the formula (alone or with mecobalamin) showed significantly better clinical outcomes than control groups. Nerve conduction velocities for both motor and sensory nerves in the median and peroneal nerves were significantly improved compared to mecobalamin alone.

2

Meta-analysis of 32 RCTs on HGWD for Chemotherapy-Induced Peripheral Neuropathy (2024)

Yang XR, Zhang XY, Xia YJ, Fu J, Lian XX, Liang XR, He YQ, Li ZH. Journal of Pain Research, 2024, 17: 2605-2628.

This systematic review and meta-analysis of 32 randomized controlled trials evaluated the formula for preventing and treating chemotherapy-induced peripheral neuropathy (CIPN). Results showed that the formula could safely and effectively prevent CIPN, reduce symptoms, improve quality of life, and reduce the impact of chemotherapy drugs on sensory nerve conduction.

3

Systematic Review and Meta-analysis on HGWWD for Oxaliplatin-Induced Peripheral Neurotoxicity (2024)

Yu J, Chen S, Wei G, Gu J, Huo J, Ding R, Li L. Alternative Therapies in Health and Medicine, 2024, 30(1): 446-453.

This meta-analysis of 18 RCTs (1,087 patients) found that the formula significantly reduced both the overall incidence and the severity of oxaliplatin-induced peripheral neurotoxicity compared to controls. The treatment group showed an overall neurotoxicity rate 0.27 times that of the control group. No increase in chemotherapy-related adverse reactions was observed.
