Also known as: Ongoing Lochia, Persistent Postpartum Bleeding, Prolonged Postpartum Bleeding, Continuous Lochia, Lochia Retention, Postpartum Discharge Retention, Retained Lochia, Abnormal Lochia, Excessive Postpartum Discharge, Lochiorrhea, Failed Afterbirth Delivery, Persistent vaginal discharge after childbirth (lochia), Prolonged postpartum bleeding (lochia), Unresolved postpartum lochia
The colour and consistency of your lochia tell a TCM practitioner more than any ultrasound. Pale, thin bleeding points to exhaustion; dark, clotted bleeding points to stagnation; red, sticky bleeding points to hidden heat - and each responds to a completely different treatment. Most women see their bleeding resolve within two to four weeks of starting pattern-specific herbs.

In TCM, lochia that continues beyond the normal three to four weeks is never just 'bleeding that won't stop.' It's a signal that the body's postpartum recovery has gone off course - and the reason could be exhaustion of Qi and blood, retained clots, or a low-grade heat that keeps the uterus from closing. Each pattern has its own characteristic discharge, its own accompanying symptoms, and its own treatment. The page below explains these patterns so you can understand what your body is trying to tell you.
In Western medicine, lochia is the normal vaginal discharge after childbirth, consisting of blood, mucus, and uterine tissue. It typically lasts three to four weeks, transitioning from red to brown to yellowish-white. When bleeding persists beyond six weeks, it is considered abnormal and may be investigated for retained placental fragments, uterine atony, infection, or subinvolution of the uterus. Diagnosis usually involves ultrasound and pelvic examination.
Conventional treatments
If retained products of conception are found, a dilation and curettage (D&C) may be performed. Antibiotics are used for infection. Uterotonics like oxytocin may be given to help the uterus contract. In cases of atony, ergometrine or misoprostol may be prescribed. Iron supplements may be recommended if blood loss has caused anemia.
Where conventional treatment falls short
While Western medicine effectively addresses mechanical causes such as retained tissue or infection, many cases of prolonged lochia remain unexplained or are attributed to 'uterine subinvolution' without a clear cause. Treatment is often limited to watchful waiting, uterotonics, or a D&C, which carries its own risks. Conventional care does not differentiate between a pale, thin discharge due to exhaustion and a dark, clotted discharge due to stagnation - yet these two presentations point to very different underlying imbalances, which TCM is designed to treat.
How TCM understands prolonged lochia
In TCM, the uterus is governed by the Chong and Ren vessels, two deep meridians that regulate menstruation, pregnancy, and postpartum recovery. Childbirth depletes Qi and blood, leaving these vessels weakened. If the Spleen and Stomach - the organs responsible for producing new Qi and blood - are too slow to replenish what was lost, the uterus lacks the strength to contract and seal its vessels. The result is a pale, thin, and often profuse lochia that continues because the body simply cannot hold blood in.
But not all prolonged bleeding comes from weakness. Sometimes the problem is stagnation. If lochia is not fully expelled after delivery, or if cold enters the lower body, blood can congeal and form clots that obstruct the uterus. These clots prevent the uterus from contracting properly, so bleeding drags on - dark, clotted, and intermittent - with a characteristic fixed pain that eases after a clot passes. This is a pattern of excess, not deficiency, and it requires moving the blood rather than tonifying.
There is also a third common scenario: Yin deficiency with empty heat. Childbirth consumes a great deal of blood and Yin, the body's cooling and moistening resources. When Yin is too depleted, a low-grade internal heat can develop. This heat agitates the blood in the uterus, preventing the vessels from closing, so lochia continues longer than normal. The discharge tends to be red, thick, and sometimes slightly smelly, accompanied by night sweats, a dry mouth, and a feeling of heat in the palms and soles. Each of these patterns requires a completely different herbal strategy - which is why TCM always begins by reading the colour, consistency, and accompanying sensations of the lochia.
「产后恶露不行，腹痛，宜生化汤主之。」
"If lochia does not flow after childbirth and there is abdominal pain, Sheng Hua Tang should be used."
How a TCM practitioner diagnoses prolonged lochia
Inside the consultation
A TCM practitioner begins by asking about the colour, consistency, amount and smell of the lochia, as well as any accompanying sensations like pain or fatigue. Because postpartum recovery draws heavily on Qi and Blood, these clues quickly point toward one of the main patterns behind prolonged lochia.
When the lochia is pale, thin and profuse, and the person feels exhausted, breathless and looks pale, the picture is one of Qi and Blood Deficiency. The tongue tends to be pale with a thin white coating, and the pulse is thready and weak, confirming that the Chong and Ren vessels lack the strength to hold blood.
If the bleeding is dark, clotted and comes and goes with a fixed, pressing lower abdominal pain that feels worse with pressure, Blood Stagnation in the Directing and Penetrating Vessels is likely. The tongue may appear dark purple or show stasis spots, and the pulse is often deep and choppy, signalling that retained lochia or cold has obstructed the uterus.
When the discharge is red, thick and sticky, sometimes with a faint foul odour, and the person notices a dry mouth, warm palms or night sweats, the pattern shifts to Empty-Heat caused by Yin Deficiency. The tongue is red with little or no coating, and the pulse is thready and rapid, reflecting yin-blood loss that has allowed deficiency heat to agitate the blood.
Less commonly, if the lochia is purplish, sticky and distinctly foul-smelling, accompanied by lower abdominal distension and a sensation of heat, the pattern is Heat and Blood Stagnation in the Lower Burner. Here the tongue is reddish-purple with stasis spots and a dry yellow coating, and the pulse is deep, choppy and rapid, reflecting trapped damp-heat and blood stasis in the pelvis.
TCM Patterns for Prolonged Lochia
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same prolonged lochia 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 perfectly normal to recognise pieces of yourself in more than one pattern, because childbirth often creates a mix of deficiency and stagnation. You might feel drained (Qi and Blood Deficiency) yet also notice some dark clots (Blood Stagnation), or have a red, sticky discharge that hints at both heat and stasis.
To narrow things down, focus on the dominant feature: the colour and consistency of the lochia, and what makes any pain better or worse. Pale, thin bleeding that worsens with exertion leans strongly toward deficiency, while dark, clotted bleeding that eases with movement points toward stagnation. A red, thick discharge with night sweats suggests yin deficiency heat.
If the lochia has a foul smell, you feel feverish or your lower belly is very tender, see a healthcare professional promptly - these signs can indicate infection. Because tongue and pulse are essential for a precise diagnosis, a TCM practitioner can help untangle overlapping patterns and select the right herbs or acupoints for your unique postpartum state.

Formulas traditionally used for prolonged lochia
4 formulas across the patterns above. The right one depends on your pattern — start with the quiz if you're unsure which fits.
A foundational formula for strengthening the digestive system and lifting the body's Qi when it has sunk or become depleted. It is commonly used for persistent fatigue, poor appetite, loose stools, and conditions involving organ prolapse (such as rectal or uterine prolapse) caused by weakness of the Spleen and Stomach. It is one of the most widely used formulas in all of Chinese medicine.
A classical postpartum recovery formula used to help the body expel residual Blood and tissue (lochia) from the uterus after childbirth, relieve lower abdominal cold pain, and support the formation of new, healthy Blood. It works by gently warming the body and promoting circulation in the uterus, making it one of the most widely used formulas for postpartum care in the Chinese medicine tradition.
A classical formula from Zhang Jingyue's Jing Yue Quan Shu designed for conditions where depleted Yin leads to internal Heat that causes abnormal bleeding. It is especially used for gynecological issues such as heavy menstrual periods, prolonged bleeding, uterine bleeding, and threatened miscarriage when accompanied by signs of Heat like warm palms and soles, a red tongue, and a rapid pulse. The formula works by simultaneously cooling the Blood to control bleeding and rebuilding the body's Yin reserves to address the root cause.
A classical formula used to break up blood stasis and clear heat from the lower abdomen. It is commonly applied for lower abdominal pain with a sense of tightness and fullness, dark-coloured menstrual blood or stools, restlessness, and nighttime fevers caused by stagnant blood binding with heat in the lower body.
For Qi and Blood Deficiency, herbs and acupuncture often reduce bleeding within two to three weeks, but full recovery of energy may take two to three months. Blood Stagnation patterns typically respond faster - within one to two weeks - as clots are cleared. Yin Deficiency with Empty Heat often improves in two to four weeks, but night sweats and dryness may take longer to resolve. Heat and Blood Stagnation, being more complex, may require three to six weeks of consistent treatment.
Treatment principles
All TCM treatments for prolonged lochia aim to restore the uterus's ability to close and to replenish what childbirth has consumed. The strategy, however, depends entirely on the underlying pattern: tonifying Qi and blood when the body is too weak to hold blood, moving stasis when clots obstruct the uterus, or clearing heat when it agitates the blood. Because postpartum women are often in a mixed state of deficiency and stagnation, formulas are carefully balanced to avoid harsh herbs that could further weaken the body.
What to expect from treatment
Most women begin with a combination of daily herbal decoctions or granules and weekly acupuncture sessions. The first sign of improvement is often a change in the colour and amount of the lochia within the first week. Bleeding typically tapers off over two to four weeks, though energy and other symptoms may take longer. Consistent treatment is key; stopping herbs too early can allow the bleeding to return.
General dietary guidance
Focus on warm, easily digestible foods that nourish Qi and blood: bone broths, congee, stewed meats, dark leafy greens, and small amounts of organ meats. Avoid cold, raw foods and icy drinks, which can constrict the uterus and promote stagnation. Minimize spicy, greasy foods that can generate heat. Ginger tea with brown sugar is a classic postpartum drink to warm the uterus and promote circulation.
Combining TCM with conventional treatment
TCM can be used alongside conventional care, but always inform both your TCM practitioner and your doctor about all treatments you are receiving. Herbs that move blood (such as Dang Gui, Chuan Xiong, and Yi Mu Cao) may increase bleeding risk if you are taking anticoagulants or have a bleeding disorder. If you have had a D&C or are on antibiotics, TCM can support recovery, but timing should be coordinated. Do not stop prescribed medications without medical advice.

Audience-specific guidance — open what applies to you
During breastfeeding, choose herbs that do not harm the infant or reduce milk supply. Bitter-cold herbs like Da Huang (rhubarb), used in Tao He Cheng Qi Tang for Heat and Blood Stagnation, may cause loose stools in the baby if used in high doses. For such patterns, milder alternatives like Yi Mu Cao (motherwort) and Pu Gong Ying (dandelion) are preferred, and acupuncture can be a safe adjunct.
Formulas that tonify Qi and Blood, such as Bu Zhong Yi Qi Tang, are generally safe and may even support lactation by boosting the mother's energy. Always consult a TCM practitioner to adjust dosages and monitor both mother and infant.
Evidence & references
Most clinical evidence for TCM treatment of prolonged lochia comes from Chinese-language randomized controlled trials. A systematic review of Sheng Hua Tang for postpartum recovery found that it significantly reduces lochia duration and promotes uterine involution, though the overall quality of trials is moderate. Acupuncture and moxibustion have also been studied, with some trials showing reduced bleeding time and improved postpartum recovery.
However, the evidence base is limited by small sample sizes and lack of blinding, and more rigorous international studies are needed to confirm these findings and establish standardized protocols.

Frequently asked questions
Common questions about using Traditional Chinese Medicine for prolonged lochia.
Most women notice a change in the colour and amount of lochia within the first week of herbs and acupuncture. Bleeding typically tapers off over two to four weeks, though the exact timeline depends on the underlying pattern. Blood Stagnation patterns often clear fastest; Qi and Blood Deficiency can take a little longer because the body needs time to rebuild reserves.
Yes, many postpartum herbal formulas are specifically designed to be safe during breastfeeding. In fact, they can support milk production by nourishing Qi and blood. However, it is essential to work with a qualified TCM practitioner who can select herbs appropriate for your pattern and avoid any that might pass into breast milk in amounts that could affect the baby. Always inform your practitioner that you are nursing.
TCM can often be used alongside conventional medications, but coordination is critical. Herbs that move blood, such as Dang Gui and Yi Mu Cao, may increase bleeding risk if you are taking anticoagulants. If you have been prescribed antibiotics or uterotonics, tell both your doctor and TCM practitioner so they can adjust timing and dosages. Never stop a prescribed medication without medical advice.
Passing small clots is common in Blood Stagnation patterns and may actually bring relief from pain. However, clots larger than a golf ball or any sudden increase in clot size can signal a more serious problem, such as retained placental tissue. In these cases, seek medical attention immediately. Your TCM practitioner can help you distinguish between normal stasis-related clotting and a red flag.
Yes. Acupuncture points such as Sanyinjiao (SP-6), Guanyuan (REN-4), and Zusanli (ST-36) are used to strengthen the Chong and Ren vessels, improve uterine contraction, and promote involution. Combined with herbs, acupuncture can accelerate the uterus's return to its pre-pregnancy size and help stop the bleeding more quickly.
Diet plays a major role in postpartum recovery from a TCM perspective. Focus on warm, nourishing foods like bone broths, congee, stewed meats, and dark leafy greens. Avoid cold, raw foods and icy drinks, which can constrict the uterus and promote stagnation. Spicy and greasy foods should be minimized as they can generate heat. Ginger tea with brown sugar is a classic postpartum drink that warms the uterus and supports circulation.
Absolutely. A C-section is a major surgery that depletes Qi and blood and can introduce cold into the lower body. TCM can be especially helpful in restoring energy, promoting healing of the incision, and addressing any lingering blood stasis from the surgery. The same pattern differentiation applies, and your practitioner will adjust herbs and points to account for the surgical recovery.
