Also known as: Febrile Diseases With Bleeding, Febrile Illness With Bleeding, Hemorrhagic Febrile Diseases, Hemorrhagic Fever, Severe viral haemorrhagic fevers, Early Stage Hemorrhagic Fevers, Haemorrhagic fevers (early stage), Epidemic Hemorrhagic Fever, Epidemic Hermorrhagic Fever
TCM doesn't treat hemorrhagic fever as one illness with one protocol - it follows the toxin's march through the body's layers, adjusting treatment at each stage to clear heat, stop bleeding, open the urine, or rebuild the Kidneys. This staged approach can help reduce the severity of the acute crisis and speed recovery from the profound weakness that follows.

Hemorrhagic fevers are a group of severe viral illnesses caused by several families of viruses, including hantaviruses, arenaviruses, and filoviruses. They are characterized by sudden onset of high fever, fatigue, muscle pain, and headache, followed by bleeding from mucous membranes and internal organs, and in some types, kidney failure.
The viruses damage blood vessels and disrupt clotting, leading to shock and multi-organ failure. Diagnosis is confirmed through blood tests detecting viral RNA or specific antibodies. Treatment is primarily supportive - maintaining fluid balance, blood pressure, and organ function - with the antiviral ribavirin effective for some types. Mortality rates vary widely depending on the virus and access to intensive care.
Conventional treatments
Conventional management focuses on intensive supportive care in a hospital setting. This includes intravenous fluids, electrolyte management, blood pressure support with vasopressors if needed, and blood transfusions for severe bleeding. Ribavirin, an antiviral, has shown benefit in Lassa fever and some hantavirus infections if given early. For other hemorrhagic fevers, no specific antiviral is available. Dialysis may be required for acute kidney injury. Prevention relies on rodent control and avoiding exposure to infected animals or bodily fluids.
Where conventional treatment falls short
While supportive care can be lifesaving, it does not directly target the underlying mechanisms of the disease from a constitutional perspective. The antiviral ribavirin is only effective for a narrow range of viruses and must be given early.
Even with intensive care, mortality remains high for certain hemorrhagic fevers, and survivors often face prolonged fatigue, kidney dysfunction, and other post-viral syndromes. Conventional medicine treats all patients with the same protocol, without differentiating the individual’s pattern of heat, fluid loss, or organ vulnerability that TCM identifies as crucial to tailoring recovery.
How TCM understands hemorrhagic fevers
TCM views hemorrhagic fevers as a severe invasion of epidemic heat-toxin (瘟邪疫毒), a pathogen far more virulent than ordinary external wind-heat. This toxin typically enters through the nose and mouth, and unlike a common cold, it penetrates the body’s defensive Wei layer almost instantly, lodging deep in the Qi level. There it generates intense fever, facial flushing, and raging thirst - the classic early stage of Qi Level Heat. The speed of this progression is a hallmark of epidemic disease, and TCM practitioners monitor it closely because it signals the need for aggressive clearing of heat before it sinks further.
If the heat is not cleared, it dives into the deeper Ying (Nutritive) and Blood levels. This is when bleeding begins - first as tiny red skin spots (petechiae), then as frank hemorrhage from the gums, nose, or internal organs. TCM explains this as Heat victorious agitating Blood: the pathogenic fire scorches the blood, forcing it out of the vessels.
At the same time, the heat disturbs the Heart Shen, causing restlessness, insomnia, and even delirium. The tongue turns deep crimson, a critical sign that the disease has reached the Blood level and that cooling the blood and stopping bleeding is now the top priority.
As the illness progresses, the epidemic toxin’s heat consumes the body’s Yin fluids and congeals the blood into stasis. This leads to the oliguric stage, where Heat and Blood Stagnation in the Lower Burner block the passage of urine. The patient passes scant, dark urine and feels a fixed, pressure-sensitive pain in the lower abdomen. TCM recognizes this as a dual pathology of heat and stasis, requiring herbs that both cool the blood and unblock the water passages.
Finally, once the toxin is cleared, the Kidneys are often left severely depleted - a pattern called Kidney Qi not Firm, characterized by excessive clear urination and deep fatigue. This recovery phase demands gentle tonification to rebuild Kidney Qi and consolidate the bladder.
「疫邪传里，胃腑受之，则潮热谵语，舌黄，腹满，不大便，此为里实，当下之。若舌紫赤，烦躁，发斑，此热入血分，宜犀角地黄汤。」
"When the epidemic pathogen penetrates the interior and lodges in the Stomach, there is tidal fever, delirium, a yellow tongue coat, abdominal fullness, and constipation - this is interior excess and should be purged. If the tongue becomes purple-red, with restlessness and skin blotches, the heat has entered the blood level; Xi Jiao Di Huang Tang is appropriate."
How a TCM practitioner diagnoses hemorrhagic fevers
Inside the consultation
A TCM practitioner traces hemorrhagic fever as a fast-moving invasion of epidemic toxin. The first question is how deep the heat has penetrated. In the earliest stage, called Qi Level Heat, the person runs a high fever, feels intense thirst, and the face and neck are visibly flushed.
The tongue is red with a dry yellow coat, and the pulse feels rapid and slippery. At this point there is no frank bleeding or mental agitation, though tiny petechiae may appear. This helps separate it from the later stages where bleeding becomes more pronounced.
When the same epidemic toxin begins to disturb the mind and the blood vessels, the pattern shifts to Heat in the Ying Level. The fever persists but now the person becomes irritable, restless, or has trouble sleeping, and tiny red spots called petechiae may appear under the skin. The tongue turns deep red with little coating, and the pulse becomes rapid and thready. This is the turning point where bleeding risk first appears.
If the heat pushes into the blood itself, the pattern becomes Heat victorious agitating Blood. Widespread bleeding follows-nosebleeds, gum bleeding, blood in the stool or urine, and large bruises. The tongue is dark red or purple, and the pulse is rapid and thready. A practitioner distinguishes this from Ying level heat by the severity and frankness of the bleeding, rather than just spots or restlessness.
As the toxin damages the lower body, Heat and Blood Stagnation in the Lower Burner takes over. Urine output drops sharply, the lower abdomen feels distended, and there may be dark, scant urine. The tongue is dark red with a thin yellow dry coat, and the pulse is deep and thready or choppy.
Later, during recovery, the pattern Kidney Qi not Firm appears: the kidneys cannot hold urine, so the person passes large amounts of clear urine, feels exhausted, and the tongue is red with little coating and a weak pulse. This sequence of change from fever to bleeding to urination problems is the key diagnostic map.
TCM Patterns for Hemorrhagic Fevers
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same hemorrhagic fevers can come from several different patterns, each treated differently. The quickest way to find yours is the quiz below.
Find your pattern
Tap any sign that fits how yours feels.
- 1Your signs
- 2What makes it worse
- 3What helps
Which signs match your experience?
It is natural to see yourself in more than one pattern because hemorrhagic fever is a single illness that moves through stages. You might have a high fever and thirst one day, then notice a few skin spots the next, which means the heat is crossing from the Qi level into the Ying level. This overlap is not a contradiction; it is the disease progressing.
To make sense of what you are experiencing, focus on the most prominent feature right now. If the main problem is still fever and thirst without bleeding, the picture leans toward the earlier heat patterns. If bleeding or dark urine becomes the dominant worry, the deeper patterns are active. The change in urine output-from very little to suddenly very much-is especially telling and marks the shift from the oliguric stage to the polyuric recovery stage.
Because hemorrhagic fevers can worsen rapidly, any combination of high fever, bleeding, and reduced urine should be treated as a medical emergency. A TCM practitioner confirms the pattern with tongue and pulse examination, but in an acute outbreak, the priority is to seek professional care immediately. Do not attempt to self-treat with herbs or acupuncture without guidance, as the wrong approach can aggravate bleeding or strain the kidneys.
If you have been exposed to rodents or traveled in an area where hemorrhagic fever is known, and you develop flu-like symptoms with any bleeding, see a doctor or TCM practitioner right away. Early differentiation of the stage allows for targeted therapy that can cool the blood, stop bleeding, and protect the kidneys before the condition deepens.

A powerful Heat-clearing formula used for severe epidemic febrile diseases where intense Heat and toxic pathogens have invaded both the Qi and Blood levels of the body. It addresses dangerously high fever, delirium, skin rashes, and bleeding by simultaneously cooling the blood and draining fire. This is an emergency formula for critical, life-threatening heat conditions and is not intended for mild or cold-type illnesses.
A classical formula for serious febrile (feverish) illnesses where Heat has penetrated deep into the body, causing high fever that worsens at night, restlessness, disturbed sleep, and sometimes delirium. It works by clearing deep-seated Heat, protecting the body's fluids from being dried out, and guiding the pathogenic Heat back outward where the body can expel it more easily.
A classical emergency formula used when severe internal Heat has entered the Blood, causing abnormal bleeding (nosebleeds, vomiting blood, blood in stool or urine), dark purple skin discolouration, high fever, and mental confusion or agitation. It works by powerfully cooling the Blood, clearing Heat toxins, nourishing depleted body fluids, and dispersing blood clots that form when Heat scorches the Blood. Originally using rhinoceros horn, modern versions substitute water buffalo horn.
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.
A classical three-herb formula used to restore vitality when both Qi and body fluids have been depleted. It addresses fatigue, shortness of breath, excessive sweating, dry throat, and weak pulse caused by heat exhaustion, chronic illness, or prolonged coughing that has weakened the Lungs. In modern practice, it is also widely used as supportive treatment for heart conditions including heart failure and irregular heartbeat.
A classical three-herb formula used to warm the Kidneys and help the Bladder hold urine properly. It is commonly used for frequent urination, bedwetting in children, and nighttime urination caused by coldness and weakness in the lower body.
In the acute hospital setting, TCM herbal treatment is intensive - decoctions may be given every few hours to aggressively clear heat and toxin. Fever and bleeding typically begin to respond within 2-4 days of combined care. The post-fever recovery phase, where Kidney Qi is rebuilt and energy restored, often requires several weeks to a few months of daily or twice-daily herbal formulas, along with acupuncture 1-2 times per week. Patients with severe Kidney damage may need longer convalescence, but TCM can help reduce the duration of weakness and support return to normal function.
Treatment principles
The overarching principle in TCM treatment of hemorrhagic fevers is to clear epidemic toxin and protect Yin and Blood at every stage. In the early Qi-level stage, the focus is on clearing heat and toxin with cold, bitter herbs. As the disease penetrates deeper, treatment shifts to cooling the blood, stopping bleeding, and opening the orifices to calm the Shen. In the oliguric stage, the strategy adds resolving stasis and unblocking water passages.
Finally, in recovery, the priority becomes nourishing Yin, tonifying Kidney Qi, and consolidating the bladder. Throughout, the goal is not just to fight the virus but to support the body’s own ability to contain the damage and restore balance.
What to expect from treatment
In the acute hospital phase, TCM treatment is intensive - herbal decoctions may be given multiple times daily, and acupuncture can be performed daily to manage fever and pain. As the patient stabilizes, treatment frequency reduces to 1-2 times per day for herbs and 2-3 times per week for acupuncture. During the convalescent phase, patients typically take herbs twice daily and receive acupuncture once or twice a week. Most notice gradual improvement in energy and reduction in urinary frequency over 4-8 weeks.
Severe cases may require longer, but TCM aims to accelerate the natural healing process.
General dietary guidance
During the acute febrile stage, the diet should be light, cooling, and easy to digest. Favor congee, steamed vegetables, and plenty of fluids like chrysanthemum tea or pear juice to support Yin and clear heat. Avoid spicy, greasy, or fried foods that can generate more internal heat. During the oliguric stage, fluid intake may need to be restricted under medical guidance, but cooling, blood-nourishing foods like spinach and cucumber can help.
In the recovery phase, gradually introduce nourishing, warming foods such as bone broths, black sesame, walnuts, and kidney beans to rebuild Kidney Qi. Avoid cold, raw foods that can further weaken the digestive fire.
Combining TCM with conventional treatment
TCM for hemorrhagic fevers must always be integrated with conventional hospital care - never as a standalone treatment. Herbal formulas can complement intravenous fluids, vasopressors, and antiviral medications, but they must be prescribed by a TCM practitioner who communicates with the medical team. Some herbs, particularly blood-moving ones like Dan Shen (Salvia root) and Tao Ren (Peach seed), may increase bleeding risk if used incorrectly, so careful monitoring is essential.
Acupuncture is safe when performed by a trained professional using sterile needles, but points on the lower back and abdomen may be avoided if there is a risk of internal bleeding. Always keep your doctors informed of all TCM treatments you are receiving.

Hemorrhagic fever during pregnancy is an extreme emergency with a high risk of miscarriage, hemorrhage, and maternal death. In TCM, pregnancy adds the complexity of the Chong and Ren channels and the need to preserve the fetus, but the overwhelming priority is to save the mother’s life by clearing the epidemic toxin.
Formulas that are heavily cold and bitter, or that strongly move blood - such as strong purgatives or blood-breaking herbs like Tao Ren - are generally avoided unless the situation is desperate and the benefit outweighs the risk.
Modified versions of Qing Wen Bai Du Yin that focus on cooling the blood without harsh movement may be used under strict specialist supervision. Acupuncture points that strongly stimulate Qi and blood downward, such as Hegu LI-4 and Sanyinjiao SP-6, are also avoided because of their traditional association with inducing labor. Every treatment decision must be made in a hospital setting with full emergency support. Self-treatment with herbs or acupuncture is absolutely contraindicated.
The severity of hemorrhagic fever means that breastfeeding must be suspended temporarily - not only because the mother is too ill but also because the epidemic toxin and the strong cold-bitter herbs used to treat it can pass into the milk and harm the infant. The mother’s body is in a fierce battle, and her Qi and fluids are being rapidly consumed, so lactation usually diminishes on its own.
Once the fever breaks and the bleeding stops, the focus shifts to restoring Yin and Qi with gentle tonics like Sheng Mai San or Liu Wei Di Huang Wan. These are safer during lactation, but a return to breastfeeding should only happen after a full recovery and with a practitioner’s guidance. Any lingering heat-clearing herbs should be cleared from the system before the infant nurses again.
In children, the epidemic toxin can move even faster because their Yin and Yang are still immature and their defensive Qi is not yet fully developed. The fever may spike abruptly, and dehydration, convulsions, and shock can develop within hours. The patterns are the same - Qi Level Heat, Ying Level Heat, Blood Heat - but the transition between them is often blurred and rapid, making continuous observation critical.
Herbal dosages must be reduced to one-quarter to one-half of the adult dose, depending on the child’s age and weight. Bitter-cold herbs should be used cautiously to avoid damaging the immature Spleen and Stomach. Acupuncture can be applied with very light stimulation or replaced by acupressure at points like Dazhui DU-14 and Quchi LI-11.
Because young children cannot describe their symptoms, the practitioner relies heavily on tongue and pulse examination, skin inspection, and close monitoring of urine output to gauge the disease’s depth and adjust treatment in real time.
Elderly patients with hemorrhagic fever face a double threat: the epidemic toxin attacks with full force while the body’s underlying Kidney and Spleen deficiencies make it harder to mount a defense and recover. Shock and acute kidney injury occur more frequently, and the polyuric recovery phase can be prolonged and exhausting.
The patterns still follow the same progression, but deficiency signs - a pale tongue body beneath the red, a weak and thready pulse - often coexist with the heat-toxin, making pure cooling formulas too harsh.
Treatment must therefore balance clearing the toxin with protecting the upright Qi. Formulas like Qing Wen Bai Du Yin may be modified by adding herbs like Dang Shen and Mai Dong to support Qi and Yin. Dosages are typically reduced to two-thirds of the adult standard, and careful attention is paid to drug interactions with any existing medications.
Acupuncture is often better tolerated than strong herbal decoctions, and gentle moxibustion on points like Guanyuan REN-4 can help support Kidney Qi during the recovery phase.
Evidence & references
The TCM treatment of hemorrhagic fevers has been studied most extensively in China, where epidemic hemorrhagic fever (Hantavirus) has been a significant public health problem. The work of Prof. Zhou Zhongying and others at Nanjing University of Chinese Medicine produced a systematic approach using Qing Wen Bai Du Yin and related formulas, with clinical reports suggesting reduced mortality and faster recovery when integrated with Western medicine.
Most published studies are observational or non-randomized and appear in Chinese-language journals, so the evidence, while clinically compelling, does not yet meet the highest international standards.
For dengue hemorrhagic fever, a 2025 Taiwanese population-based study using a national health insurance database found that several TCM formulas and single herbs were associated with a lower risk of progressing to severe dengue. These include Lonicerae Japonicae Flower, Scutellaria Root, and Gan-Lu-Yin, all of which align with the TCM principle of clearing heat and detoxifying.
Rigorous randomized controlled trials are still needed, but the existing clinical experience and preliminary data support a valuable role for TCM as an adjunctive treatment in severe viral hemorrhagic diseases.
Key clinical studies
This nationwide cohort study analyzed Taiwanese health insurance data to identify TCM formulas and herbs associated with reduced progression to severe dengue hemorrhagic fever. Herbs such as Lonicerae Japonicae Flower (Jin Yin Hua), Scutellaria Root (Huang Qin), and formulas like Gan-Lu-Yin were significantly protective, supporting the heat-clearing and detoxifying approach used in TCM for hemorrhagic fevers. In vitro assays confirmed antiviral and anti-inflammatory effects of several key herbs.

「太阳病不解，热结膀胱，其人如狂，血自下，下者愈。其外不解者，尚未可攻，当先解其外；外解已，但少腹急结者，乃可攻之，宜桃核承气汤。」
"When a Taiyang disease does not resolve and heat binds in the bladder, the patient behaves as if manic, and blood may pass spontaneously - if it does, recovery follows. If the exterior is not yet resolved, do not attack; first release the exterior. Once the exterior is resolved, if there is only acute tightness in the lower abdomen, then attack, using Tao He Cheng Qi Tang."

Frequently asked questions
Common questions about using Traditional Chinese Medicine for hemorrhagic fevers.
No. Hemorrhagic fevers are medical emergencies that require immediate hospitalization. TCM treatment for this condition is always integrated with intensive conventional care - never self-administered at home. If you have high fever with bleeding, severe headache, or reduced urine, go to an emergency room immediately. TCM herbs can support recovery after the acute phase under professional guidance, but the acute illness must be managed in a hospital.
In a hospital setting, acupuncture can be used to support organ function and manage symptoms. Points like Hegu LI-4 and Quchi LI-11 help reduce fever; Xuehai SP-10 and Sanyinjiao SP-6 help cool the blood and stop bleeding; and Shenshu BL-23 and Guanyuan REN-4 support kidney function during the oliguric and polyuric stages. Acupuncture is not a substitute for emergency care but can be a valuable adjunct to help the body cope with the severe stress of the illness.
The formulas depend entirely on the stage. In the early Qi Level Heat stage, Qing Wen Bai Du Yin (Clear Epidemics and Overcome Pathogenic Influences Decoction) with herbs like Shi Gao (Gypsum) and Huang Lian (Coptis) is used to clear intense heat. When heat enters the Blood level, Xi Jiao Di Huang Tang (Rhinoceros Horn and Rehmannia Decoction) or modifications with Di Huang (Rehmannia) and Mu Dan Pi (Moutan) cool the blood and stop bleeding. For the oliguric stage, Tao He Cheng Qi Tang (Peach Pit Decoction to Order the Qi) unblocks the lower burner.
During recovery, Suo Quan Wan (Shut the Sluice Pill) with Wu Yao and Yi Zhi Ren consolidates Kidney Qi. All are prescribed by a trained practitioner and are not for self-use.
In the oliguric stage, TCM aims to resolve blood stasis and open the urine passage with herbs like Tao Ren (Peach Seed) and Da Huang (Rhubarb), which may help restore urine output and reduce the burden on the kidneys. While severe cases may still require dialysis, TCM can support kidney recovery and potentially shorten the duration of renal support. This is always done under close medical supervision in a hospital.
The acute phase with fever and bleeding usually lasts 1-2 weeks. With integrated TCM care, the fever may break sooner and bleeding may be controlled more quickly. The convalescent phase - marked by fatigue, frequent urination, and lower back soreness - can last several weeks to months. TCM herbs and acupuncture during this time can significantly speed recovery of Kidney Qi and overall energy, with many patients feeling substantially stronger within 4-8 weeks of consistent treatment.
Yes, TCM herbs and acupuncture are generally safe when used alongside ribavirin and supportive hospital care, provided both your TCM practitioner and medical team are fully informed. Some herbs, particularly those that move blood (like Dan Shen, Tao Ren), may interact with anticoagulants or affect clotting, so it’s critical that all medications are disclosed. Never combine TCM with conventional treatment without the knowledge of your doctors.
