Also known as: Genitalia ulcers, Scrotum ulcers, Vulvar Sores, Sores On The Vulva, Vulval Ulcers
The red, weeping ulcer, the hard stubborn nodule, and the pale slow-healing sore are three different patterns - and each responds to a different herbal strategy. When the pattern is correctly identified, many genital ulcers begin to improve within one to two weeks.

Genital ulcers aren't a single condition in TCM - they're a family of five distinct patterns, each with its own cause, its own characteristic appearance, and its own treatment. Two are acute Heat patterns (Damp-Heat and Toxic-Heat) where inflammation and toxicity are the driving force.
One is a Blood Stagnation pattern where Heat has damaged the local blood flow, causing a dark, fixed sore. One is a Phlegm accumulation pattern where a stubborn, nodular ulcer resists healing. And one is a deficiency pattern (Qi and Blood Deficiency) where the body simply lacks the resources to close the wound. TCM's approach identifies which pattern is at play and treats accordingly, addressing both the ulcer and the person.
Conventional treatments
Where conventional treatment falls short
How TCM understands genital ulcers
In TCM, a genital ulcer is never just a local sore. It is a visible sign of an internal imbalance, most often involving the Liver, Spleen, and Kidney organ systems and the lower burner - the body's pelvic basin. The Liver channel wraps around the genitals, so when Heat, Dampness, or stagnation accumulates in this channel, it can erupt as a lesion.
The Spleen is responsible for transforming fluids; when it is weak, dampness gathers and can pour downward. The Kidneys govern the body's fundamental Yin and Yang, and their depletion can lead to deficiency patterns where ulcers fail to heal.
Because different imbalances produce different types of ulcers, TCM distinguishes several patterns. A red, moist, weeping ulcer with yellow discharge points to Damp-Heat - a combination of pathogenic moisture and Heat that has settled in the lower body. A hard, stubborn ulcer with swollen lymph nodes signals Toxic-Heat, a more intense, fiery toxicity.
When the ulcer is dark, fixed, and stabbing, Heat has entered the Blood level and caused stagnation. A pale, nodular, heavy-feeling ulcer suggests Phlegm - congealed dampness that has become cold and stuck. And a shallow, pale sore that just won't heal reflects Qi and Blood Deficiency, where the body lacks the vital energy and nourishment to repair tissue.
This is why two people with genital ulcers can receive completely different herbal formulas and acupuncture point prescriptions from a TCM practitioner. The treatment matches the pattern, not just the symptom. The tongue and pulse provide critical clues: a red tongue with greasy yellow coating and a slippery rapid pulse confirm Damp-Heat, while a pale tongue with a weak pulse points to deficiency. By reading these signs, the practitioner can choose the right strategy - whether to clear Heat and drain Dampness, resolve toxicity, move Blood, transform Phlegm, or nourish Qi and Blood.
「下疳者，邪淫欲火郁滞而成。其形如粟米，或如豆粒，渐渐腐烂，疼痛难忍，甚则寒热交作。」
"Xia Gan (genital chancre) arises from the stagnation of pathogenic lustful fire. It begins as a millet-sized or bean-sized lesion, gradually ulcerates, causing unbearable pain, and in severe cases, alternating chills and fever."
How a TCM practitioner diagnoses genital ulcers
Inside the consultation
When you see a TCM practitioner for a genital ulcer, they start by looking closely at the sore itself - its color, whether it is weeping or dry, how deep it is, and what the surrounding skin looks like. These local clues, combined with your overall energy and comfort, help them identify which pattern is driving the problem.
If the ulcer is red, swollen, and moist with a yellowish discharge, the main culprit is usually Damp-Heat in the Lower Burner. Your tongue will often appear red with a thick, greasy yellow coating, and your pulse feels slippery and rapid. This pattern is very common in the early stages and reflects dampness and heat pouring downward to the genital area.
When the sore is firm, stubbornly refuses to heal, and nearby lymph nodes are swollen and tender, Toxic-Heat has taken hold. The tongue coating is thick and yellow, and the pulse is rapid and forceful. This pattern may arise on its own or develop from unresolved Damp-Heat, signaling a deeper, more intense heat toxicity that needs strong clearing.
If the ulcer is deep, dark, and intensely painful, and your tongue looks purplish with a choppy pulse, Heat has moved into the Blood level and caused stagnation. This Heat and Blood Stagnation in the Lower Burner pattern often appears when the condition has been lingering or is particularly severe, and it requires both cooling the blood and moving stasis.
In longer-standing cases, the sore may feel hard or nodular, and your tongue coating is sticky and greasy while the pulse is slippery or choppy. This points to Phlegm in the Lower Burner, where dampness and heat have congealed into a more stubborn, phlegm-like blockage that is difficult to resolve.
Finally, if the ulcer looks pale, shallow, and fails to close up despite treatment, and you feel generally drained with a pale tongue and a weak, thready pulse, your body’s Qi and Blood are depleted. This Qi and Blood Deficiency pattern is more common in late or recurrent cases, where the body simply lacks the nourishment to repair the tissue.
TCM Patterns for Genital Ulcers
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same genital 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 is not unusual to see a mix of patterns in yourself. For example, a sore that starts with redness and weeping (Damp-Heat) may later become firm and stubborn (Toxic-Heat) or turn dark and painful (Blood Stasis). Overlap is common, especially in conditions that have been present for a while.
To get a clearer picture, pay attention to which feature bothers you most and what makes it feel better or worse. An ulcer that oozes and feels hot points toward damp-heat, while one that is rock-hard and unyielding leans toward toxic-heat or phlegm. If you feel exhausted and the sore just won’t heal, deficiency may be playing a role.
Because these patterns can shift and combine, and because the tongue and pulse provide essential information you cannot see on your own, a professional TCM diagnosis is very valuable. A practitioner can feel the pulse quality and inspect the tongue coating to distinguish between, say, damp-heat and blood stasis, which may require very different herbal strategies.
If the ulcer is severe, rapidly worsening, or accompanied by fever, significant weight loss, or swollen lymph nodes that do not go down, seek medical attention promptly. Self-treatment is not appropriate for serious genital sores, and a TCM practitioner can work alongside your doctor to support healing safely.

Four ways to address genital ulcers in TCM — explore each, or take the quiz to see what fits you first.
Formulas traditionally used for genital ulcers
6 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A powerful cooling formula used to address conditions caused by excess heat and dampness in the Liver and Gallbladder systems. It is commonly used for red, painful eyes, headaches, ear problems, irritability, urinary difficulties, and skin conditions like shingles, particularly when accompanied by a bitter taste in the mouth, dark urine, and a feeling of heat or inflammation along the sides of the body or in the genital area.
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 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 designed to improve blood circulation in the chest, relieve pain, and ease emotional tension. It is widely used for chronic chest pain, stubborn headaches, insomnia, and irritability caused by poor blood flow and stagnation in the upper body.
A foundational formula used to clear excess phlegm and dampness from the body, especially when they cause coughing with white phlegm, nausea, chest tightness, dizziness, or a heavy feeling in the limbs. It works by drying dampness, dissolving phlegm, and supporting healthy digestion. Named for its two key ingredients, Ban Xia and Chen Pi, which are most effective when aged.
A classical formula that simultaneously replenishes both Qi and Blood, created by combining two famous prescriptions: Si Jun Zi Tang (for Qi) and Si Wu Tang (for Blood). It is commonly used for people who feel chronically tired, look pale or sallow, have a poor appetite, experience dizziness or heart palpitations, and feel generally run down due to dual deficiency of Qi and Blood.
Acute Damp-Heat or Toxic-Heat ulcers often show reduced redness and discharge within 1-2 weeks of starting herbs and acupuncture. Blood Stagnation or Phlegm patterns may take 3-6 weeks to soften and begin healing. Deficiency patterns require longer - often 6-12 weeks - to rebuild Qi and Blood and close the ulcer. Consistent treatment and dietary adjustments are key.
Treatment principles
What to expect from treatment
General dietary guidance
To support healing, avoid foods that generate Dampness and Heat: fried foods, alcohol, spicy dishes, rich dairy, and excessive sugar. Instead, emphasize cooling, easily digestible foods like steamed vegetables, congee, and light soups. Bitter greens (dandelion, chicory) and foods like celery and cucumber help drain Damp-Heat.
If your ulcer is pale and your energy is low (deficiency pattern), you may need warmer, more nourishing foods - consult your practitioner for tailored advice. Drink plenty of room-temperature water, and avoid iced drinks, which can impair digestion.

Audience-specific guidance — open what applies to you
Pregnancy demands extreme caution when treating genital ulcers with Chinese herbs. Many of the key formulas for Damp-Heat and Toxic-Heat patterns - such as Long Dan Xie Gan Tang and Wu Wei Xiao Du Yin - contain bitter-cold, downward-draining herbs that can stimulate uterine contractions or affect fetal development. Chai Hu (Bupleurum) and Mu Tong (Akebia) are particularly avoided.
Instead, acupuncture is the preferred first-line treatment during pregnancy, using points like Sanyinjiao (SP-6) cautiously and avoiding lower abdominal points. For Qi and Blood Deficiency ulcers, gentle tonics like Ba Zhen Tang may be used under strict supervision, but only after the first trimester. Topical herbal washes with mild, cooling herbs like Jin Yin Hua (Lonicera) are generally safe and can provide local relief without systemic risk.
While breastfeeding, bitter-cold herbs such as Huang Qin (Scutellaria), Huang Lian (Coptis), and Long Dan Cao (Gentian) can pass into breast milk and cause loose stools or digestive upset in the infant. Therefore, formulas like Long Dan Xie Gan Tang and Huang Lian Jie Du Tang should be avoided or used only for very short courses under professional guidance.
Milder alternatives, such as topical applications of Jin Yin Hua (Lonicera) wash or compresses, are safer. If a systemic formula is necessary, Ba Zhen Tang for deficiency patterns is generally well-tolerated and may even support milk supply. Acupuncture remains a safe and effective option throughout breastfeeding, with points selected to clear damp-heat or tonify qi and blood without affecting milk quality.
Genital ulcers in children are uncommon and warrant thorough medical investigation. In TCM, when they do occur, they are most often due to Damp-Heat or Toxic-Heat patterns stemming from poor hygiene, dietary irregularities, or external invasion. Children's Spleen Qi is inherently immature, so dampness can easily accumulate.
Herbal dosages must be significantly reduced - typically one-third to one-half of the adult dose, depending on the child's age and weight. Bitter-cold formulas like Long Dan Xie Gan Tang should be used for the shortest time possible to avoid damaging the Spleen. Acupuncture can be replaced by acupressure or pediatric tuina on points such as Sanyinjiao (SP-6) and Zusanli (ST-36). Topical soothing washes with Jin Yin Hua are gentle and effective. The primary goal is to clear the pathogen while protecting the developing digestive function.
In elderly patients, genital ulcers are more likely to present with underlying deficiency patterns - particularly Qi and Blood Deficiency - even if some Damp-Heat or Toxic-Heat signs are present. The body's healing capacity is diminished, so ulcers tend to be pale, shallow, and very slow to close.
Treatment must prioritize supporting the patient's vital energy. Harsh, bitter-cold formulas like Long Dan Xie Gan Tang can further weaken the Spleen and Stomach, so they should be used sparingly and at reduced dosages (typically two-thirds of the adult dose). Ba Zhen Tang or modifications of it are often the cornerstone, with small amounts of damp-clearing herbs added as needed. Acupuncture is well-tolerated, but points should be needled gently and fewer needles used per session. Recovery timelines are longer, and a strong emphasis on dietary therapy with warm, nourishing foods is essential.
Evidence & references
The evidence base for TCM treatment of genital ulcers is limited and largely consists of small, uncontrolled Chinese-language studies. Most trials focus on specific conditions that cause genital ulcers, such as genital herpes or Behçet's disease, rather than the symptom itself. Acupuncture and Chinese herbal medicine, particularly formulas like Long Dan Xie Gan Tang, have shown promise in reducing ulcer healing time and recurrence rates, but the methodological quality is often low.
A 2013 systematic review of Chinese herbal medicine for Behçet's disease found that combination therapy with conventional medication improved outcomes, though the evidence was not robust. There is a clear need for well-designed, placebo-controlled RCTs to validate these preliminary findings. At present, TCM is best considered a complementary approach, and any treatment should be supervised by a qualified practitioner.
Key clinical studies
This randomized controlled trial compared Long Dan Xie Gan Tang with oral acyclovir in 60 patients. The herbal group showed a comparable reduction in healing time and significantly lower recurrence rate at 6-month follow-up, supporting its use for Damp-Heat pattern genital ulcers.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for genital ulcers.
TCM can help resolve many types of genital ulcers by addressing the underlying imbalance that allowed them to develop. However, if the ulcer is caused by an infection like syphilis or herpes, TCM should be used alongside conventional medical treatment, not as a replacement. Always get a proper diagnosis first.
Many people notice less pain and discharge within the first week. Complete healing depends on the pattern: acute heat patterns may resolve in 2-4 weeks, while chronic or deficiency-related ulcers can take 2-3 months. Your practitioner will monitor progress and adjust the formula as the ulcer changes.
Yes, TCM is often used alongside conventional medications. Herbs can support the body's healing and reduce side effects. However, always inform both your TCM practitioner and your medical doctor about all treatments you are using. Some herbs may interact with medications, so coordination is essential.
In general, avoid spicy, greasy, and overly sweet foods, as they create Dampness and Heat. Focus on cooling, light foods like cucumber, mung beans, and leafy greens. Drink plenty of water. If your ulcer is pale and slow-healing (deficiency pattern), your practitioner may recommend warming, nourishing foods instead.
Pregnancy requires special caution. Some herbs that move Blood or clear Heat are contraindicated. Always tell your practitioner if you are pregnant or trying to conceive. Acupuncture can be safe when performed by a trained professional who avoids certain points. For any genital ulcer during pregnancy, consult your obstetrician first.
TCM aims to correct the root imbalance, so recurrence is less likely once the pattern is resolved. However, if the underlying triggers - such as poor diet, chronic stress, or a weak constitution - return, the ulcer could reappear. Your practitioner will give you lifestyle and dietary advice to maintain balance.
