A chronic ulcer is not just a wound - it is a mirror of your body's inner vitality. By identifying whether the root is a depletion of Qi and Blood, a knot of Liver stagnation, or a flare of toxic heat, TCM can guide healing from the inside out, often with visible new granulation within 4 to 8 weeks.

Chronic ulcers aren't just a wound that refuses to close - in Traditional Chinese Medicine, they are a visible signal that the body's deepest resources are depleted. Where Western medicine focuses on the wound bed, TCM looks at why your body has stopped building new tissue. The same non-healing sore can stem from a profound lack of Qi and Blood, a long-standing emotional knot that has congealed into stuck Blood, or a sudden flare of toxic heat on top of an old weakness. Each of these patterns needs a fundamentally different treatment, which is why a one-size-fits-all approach often falls short.
A chronic ulcer is defined as a wound that has failed to heal within 4 to 12 weeks despite appropriate care. The most common types include venous stasis ulcers, arterial insufficiency ulcers, diabetic foot ulcers, and pressure injuries. Diagnosis typically involves a physical examination, wound measurement, assessment of blood flow (ankle-brachial index, Doppler ultrasound), and screening for underlying conditions like diabetes or peripheral artery disease.
Conventional treatment centers on removing dead tissue (debridement), controlling infection, managing moisture with specialized dressings, and offloading pressure. When circulation is severely compromised, surgical revascularization or amputation may become necessary. Despite these measures, many ulcers persist for months or years, significantly reducing quality of life.
Conventional treatments
Standard care includes sharp or enzymatic debridement, moisture-balancing dressings (hydrocolloids, alginates, foams), compression therapy for venous ulcers, total contact casting for diabetic foot ulcers, and systemic antibiotics when infection is present. Advanced therapies such as negative pressure wound therapy, hyperbaric oxygen, skin grafts, and growth factor gels may be used for stubborn wounds. Pain management and nutritional support are also key components.
Where conventional treatment falls short
Conventional wound care excels at managing the local environment but often overlooks the systemic factors that prevent healing - poor circulation, immune dysfunction, chronic inflammation, and nutritional deficiencies. Even with meticulous local care, many ulcers stall because the body simply lacks the raw materials and energetic drive to regenerate tissue.
Treatments like compression and offloading are essential but do nothing to correct the underlying constitutional weaknesses that allowed the ulcer to form in the first place. This is precisely where TCM's whole-body approach can make a critical difference.
How TCM understands chronic ulcers
TCM sees a chronic ulcer as a failure of the body to generate new flesh - a process governed primarily by the Spleen and Stomach, which produce Qi and Blood from the food we eat. When Spleen Qi is weak, the body cannot manufacture enough vital substance to knit the wound closed. The ulcer stays open with pale, watery granulation and the person feels exhausted, eats poorly, and looks pale. This deficiency pattern is the most common root of a chronic ulcer.
But the Spleen is only one piece of the puzzle. The Liver is responsible for the smooth flow of Qi and Blood throughout the body. Long-standing emotional stress, frustration, or anger can cause Liver Qi to stagnate and eventually congeal into Blood stasis. This creates a hard, painful nodule at the ulcer site that refuses to soften or drain. The wound feels stuck - much like the emotions that triggered it. Here the tongue often shows purple spots or a dark hue, and the pulse feels wiry and choppy.
Sometimes a chronic ulcer flares up into an acute crisis - the wound becomes red, swollen, hot, and pours thick yellow pus. This is Toxic-Heat Stagnation, an invasion of pathogens that overwhelms the body's weakened defenses. It is an excess condition on top of a deficiency background, and must be cleared quickly before it damages tissue further. Finally, in rare cases where the body's Yang fire is nearly extinguished, a Wind-Cold invasion can further congeal Qi and Blood, leaving the ulcer cold, pale, and utterly stagnant - a pattern that demands deep warming and resuscitation.
「久不收口者，气血虚也，宜补脾胃，生肌肉。」
"If the ulcer does not close for a long time, it is due to deficiency of Qi and Blood; it is appropriate to tonify the Spleen and Stomach to generate flesh."
How a TCM practitioner diagnoses chronic ulcers
Inside the consultation
A TCM practitioner begins by looking at the ulcer itself and asking about your energy, sleep, and digestion. A chronic sore that barely heals, with pale pink granulation and watery discharge, often points to a deep deficiency of Qi and Blood, especially of the Heart and Spleen. The person may feel exhausted, look pale, and have a pale, puffy tongue. This pattern is about the body lacking the resources to build new tissue.
If the ulcer feels hard like a nodule and the pain is fixed in one spot, the practitioner suspects Liver Blood Stagnation. Emotional stress or long-term frustration can cause Qi to get stuck, which eventually congeals into blood stasis. The tongue often shows purple spots or a dark hue, and the pulse feels wiry and choppy. The ulcer may resist softening or draining, reflecting the stagnation.
During an acute flare-up, the sore may become red, swollen, hot, and painful, oozing thick yellow pus. This signals Toxic-Heat Stagnation, where dampness and heat have accumulated locally. The tongue appears red with a greasy yellow coat, and the pulse is rapid and slippery. This pattern is more about an active infection or inflammation that needs clearing, unlike the slow, non-healing deficiency patterns.
Rarely, a chronic ulcer can present with a sudden onset of chills, body aches, and a pale tongue, suggesting an invasion of Wind-Cold on top of an underlying Yang deficiency. The body’s defensive energy is too weak to push the pathogen out, and the ulcer may feel cold or look stagnant. A classic formula for this is Mahuang Fuzi Xixin Tang, which warms Yang and releases the exterior.
TCM Patterns for Chronic Ulcers
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same chronic ulcers can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.

Which signs match your experience?
It’s common to see a mix of patterns. A long-standing ulcer might start with a toxic-heat flare-up but later become a deficiency pattern, or a blood stasis knot may develop because Qi and Blood are too weak to move properly. Overlap is the rule, not the exception, because chronic illness often involves both root deficiency and branch excess.
If you notice signs of both heat (redness, pus) and fatigue (pale complexion, weakness), or a hard lump alongside exhaustion, you are likely dealing with a combination. Pay attention to what makes it worse: does stress tighten the nodule? Does overwork cause more oozing? These clues help, but a professional can see the full picture by examining your tongue and pulse.
Because chronic ulcers can be stubborn and may hide deeper imbalances, self-treatment is risky. If the ulcer is rapidly expanding, extremely painful, or accompanied by fever, seek medical care immediately. A TCM practitioner can safely combine herbs to address both the root deficiency and any acute heat or stasis, guiding healing without harming your vitality.

Formulas traditionally used for chronic ulcers
5 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A classical formula that strengthens the Spleen and nourishes the Heart to address fatigue, poor appetite, insomnia, forgetfulness, palpitations, and anxiety caused by weakness of both the Heart and Spleen. It is also widely used for bleeding disorders such as heavy or prolonged menstrual periods, easy bruising, or blood in the stool that result from the Spleen being too weak to keep blood in its proper channels.
A classical formula that both nourishes and invigorates the Blood, used to address menstrual irregularities, period pain, and other conditions caused by Blood stagnation combined with Blood deficiency. It builds on the famous Si Wu Tang (Four-Substance Decoction) by adding Peach Kernel and Safflower to strengthen its ability to move stagnant Blood and promote healthy circulation.
A powerful classical formula that clears intense heat and toxins from all levels of the body. It is used for conditions involving high fever, restlessness, infections, skin eruptions, and bleeding caused by excessive internal heat. Because it is strongly cooling, it is intended only for acute, excess-heat conditions and not for long-term use.
A classical formula that uses five potent heat-clearing herbs to fight infections and inflammation, especially boils, abscesses, and other skin infections that present with redness, swelling, heat, and pain. It is one of TCM's most direct and powerful formulas for clearing toxic heat from the body.
A classical formula from the Shang Han Lun designed for people who catch a cold when their body is already weakened, particularly when they feel extremely cold, deeply tired, and have a weak pulse. It works by warming the body's core while gently helping it expel the cold from the surface. It is also widely used in modern practice for conditions like allergic rhinitis, slow heart rate, and cold-type joint pain when the underlying pattern involves Yang deficiency.
For acute Toxic-Heat flares, symptoms often improve within days of starting herbs, with the ulcer settling back to its chronic state in 1 to 2 weeks. Blood Stagnation patterns typically show softening of the ulcer edge and reduced pain within 3 to 6 weeks. Deep Qi and Blood Deficiency - the most common root - requires 3 to 6 months of consistent treatment to rebuild the body's reserves and achieve stable closure. Ulcers that have been open for years may take longer, but steady progress is the norm.
Treatment principles
Treatment of chronic ulcers in TCM always addresses both the root and the branch. The root is the underlying deficiency - usually of Qi and Blood - that has left the body unable to repair itself. The branch is the local stagnation, whether it manifests as Blood stasis, Toxic Heat, or Dampness. A typical strategy combines internal herbal formulas to tonify the Spleen, nourish Blood, move Liver Qi, or clear Heat, with external applications to directly treat the wound.
Because chronic ulcers often present as mixed patterns - a background of deficiency with a flare of Heat, or Blood stasis complicating Spleen weakness - formulas are frequently adjusted every few weeks as the wound evolves. Acupuncture and moxibustion are used to support the internal organs and improve local circulation. The goal is not just to close the skin, but to restore the body's own capacity to heal, so the closure is durable.
What to expect from treatment
You will likely begin with weekly acupuncture sessions and a daily herbal decoction or concentrated powder. External herbal washes or ointments may be applied between visits. In the first 2 to 4 weeks, you may notice less pain, reduced discharge, and a healthier wound bed. Actual wound contraction usually becomes visible by week 6.
For deep deficiency patterns, treatment may continue for several months, with gradual tapering of herbs once the ulcer is closed. Patience is essential - a wound that has been open for a year will not close in a week, but steady, predictable progress is the hallmark of successful TCM treatment.
General dietary guidance
In TCM, the Spleen and Stomach are the source of all the Qi and Blood needed to heal a wound, so diet is foundational. Eat warm, cooked foods that are easy to digest - rice congee, soups, stews, steamed vegetables. Include moderate amounts of high-quality protein (chicken, fish, eggs) and blood-nourishing foods like dark leafy greens, red dates, goji berries, and black sesame. Avoid cold drinks, raw salads, ice cream, and greasy or deep-fried foods, which damage Spleen Yang and generate Dampness. During a Toxic-Heat flare, eliminate spicy foods, alcohol, and coffee until the redness and heat subside.
Combining TCM with conventional treatment
TCM is generally safe to combine with conventional wound care, and many patients use both simultaneously. Continue your prescribed dressings, compression therapy, and offloading devices. Herbal formulas that contain Blood-moving ingredients (Dang Gui, Tao Ren, Hong Hua, Dan Shen) may potentiate anticoagulant or antiplatelet drugs - always inform your prescribing doctor and TCM practitioner of all medications.
Some herbs can affect blood sugar; diabetic patients should monitor glucose closely when starting herbs. External herbal preparations should be sterile and used only as directed. Never apply an herbal paste to a wound without your practitioner's approval, as improper application can introduce infection.

Audience-specific guidance — open what applies to you
During pregnancy, the body’s demand for Blood intensifies, which can worsen a pre-existing Blood Deficiency pattern behind a chronic ulcer. Gui Pi Tang is generally considered safe, but the Dang Gui it contains should be used cautiously and in reduced dosage, as it has a mild blood-moving property. Acupuncture is often preferred as a first-line treatment, with points like Zusanli ST-36 and Sanyinjiao SP-6 being both safe and effective. Strong blood-moving herbs such as Tao Ren and Hong Hua are contraindicated throughout pregnancy.
During breastfeeding, avoid strong bitter-cold formulas like Huang Lian Jie Du Tang, as they can diminish milk supply and may cause infant diarrhea through the breast milk. For a Toxic-Heat flare in a chronic ulcer, favour milder heat-clearing herbs such as Jin Yin Hua and Pu Gong Ying. Gui Pi Tang and Tao Hong Si Wu Tang are generally safe, but always consult a TCM practitioner to ensure no harmful amounts of active compounds pass into the milk.
Chronic ulcers are uncommon in children. When they occur, Spleen Qi Deficiency is often the root, sometimes with a component of Damp-Heat. Gui Pi Tang can be used at one-third to one-half of the adult dose, adjusted for the child’s age and weight. Acupuncture is well-tolerated by many children, but non-needle techniques such as pediatric tuina or acupressure may be preferred. Strong blood-moving herbs should be avoided.
In the elderly, chronic ulcers are frequently driven by Qi and Blood Deficiency, often complicated by Blood Stasis from long-standing vascular disease. Gui Pi Tang and Tao Hong Si Wu Tang are cornerstone formulas, but dosages should be reduced to about two-thirds of the standard adult dose. Moxibustion on Zusanli ST-36 and Guanyuan REN-4 can powerfully stimulate healing. Always monitor for potential interactions with conventional medications and adjust treatment timelines, as healing is naturally slower.
Evidence & references
Clinical research on TCM for chronic ulcers is growing but remains limited. A clinical study on a twin-herb formula combining Huang Qi (Astragalus) and Dang Gui (Angelica sinensis) showed significant improvement in wound healing and a reduction in inflammatory markers. Several Chinese-language trials have reported positive outcomes for formulas like Gui Pi Tang and topical preparations such as Xiaojie Shuang paste.
However, most studies are small, lack rigorous blinding, and are not published in English. The evidence base is not yet strong enough for definitive conclusions, but the results are promising and align with centuries of clinical experience. Acupuncture has also been shown to improve local blood flow and reduce pain in chronic wounds, though large-scale randomized controlled trials are needed.
Key clinical studies
This clinical study evaluated a decoction of Huang Qi (Astragalus membranaceus) and Dang Gui (Angelica sinensis) in patients with chronic non-healing ulcers. Results showed accelerated wound closure, reduced TNF-α and CRP levels, and improved granulation tissue formation compared to standard wound care.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for chronic ulcers.
Yes, but it works indirectly. Acupuncture does not close the wound by itself. Instead, it stimulates the body's healing resources - boosting Spleen Qi to generate new tissue, moving stagnant Liver Blood to improve local circulation, and clearing Heat and Dampness that block repair. Needles are rarely placed in the ulcer itself; points on the legs, abdomen, and back do the work. Most patients notice less pain and discharge within a few sessions.
For chronic ulcers, internal herbal formulas are usually essential because the root of the problem is a systemic imbalance. External washes, ointments, or poultices can be very helpful to clear local Heat, reduce swelling, and promote granulation, but they rarely work alone on a wound that has been open for months. A combination of internal and external treatment gives the best results.
Most patients notice a change within 4 to 6 weeks - the ulcer base may become pinker, discharge less, and the edges may begin to pull in. Actual closure depends on the size and depth of the wound and the severity of the underlying deficiency. A small ulcer might close in 2 to 3 months; a large or very old ulcer can take 6 months or more. Your TCM practitioner will check your tongue and pulse regularly to track progress even before the wound visibly shrinks.
Yes, and in fact the two approaches often work well together. Continue your prescribed dressings, compression, and offloading. Tell both your TCM practitioner and your wound care doctor about all treatments you are receiving. Certain Blood-moving herbs (such as Dang Gui, Tao Ren, and Hong Hua) can interact with anticoagulant medications like warfarin - always disclose your full medication list. External herbal applications should be prepared under sterile conditions and never applied to a wound without your practitioner's guidance.
TCM aims to prevent recurrence by correcting the underlying weakness that allowed the ulcer to form. When treatment successfully rebuilds Spleen Qi and Blood, resolves Blood stasis, and clears lurking Dampness and Heat, the healed skin is stronger and less likely to break down again. However, if the original triggers return - prolonged standing, poor diet, emotional stress, or uncontrolled diabetes - the risk remains. Your practitioner will often recommend periodic herbal 'tune-ups' and dietary habits to maintain the gain.
Diet plays a major role in TCM wound healing. Generally, avoid cold, raw, greasy, and spicy foods that damage the Spleen or create Dampness and Heat. Favor warm, cooked, easily digested meals like congee, soups, and bone broth. Blood-nourishing foods - dark leafy greens, red dates, goji berries, and small amounts of high-quality meat - can help rebuild tissue. If you have a Toxic-Heat flare, strictly avoid alcohol, chili, and fried food until it subsides.
If you notice rapidly spreading redness, fever, chills, severe pain, or foul-smelling discharge, stop home treatment and seek urgent medical care. These are signs of a serious infection that needs immediate attention. Once the acute crisis is managed, TCM can help you recover and rebuild.
