How TCM understands delirium
「陽明者……病甚則棄衣而走，登高而歌，或至不食數日，逾垣上屋，所上之處，皆非素所能也。」
"When the Yangming is severely diseased, the patient will throw off their clothes and run about, climb to high places and sing, or go without food for days, leaping over walls and onto roofs - places they could never reach in normal health. This describes the hyperactive, agitated type of delirium."
How a TCM practitioner diagnoses delirium
Inside the consultation
A TCM practitioner approaches delirium by listening carefully to the story: when it started, how the person behaves, and what their body reveals. The quality of the confusion-quiet and withdrawn, or loud and agitated-is a key first clue, along with tongue and pulse signs that point toward the underlying imbalance.
When phlegm turbidity clouds the mind, the person appears dull, lethargic, and confused-often the quiet, hypoactive type of delirium. They may mumble, seem indifferent, or have a greasy tongue coating and a slippery pulse. The practitioner suspects this pattern when confusion is heavy and muffled rather than fiery, often in older or chronically ill individuals with weak digestion.
If the delirium is hyperactive-shouting, restlessness, aggression, red face, and a sensation of heat-this points to phlegm-fire flaring upward. The tongue is red with a yellow greasy coating, and the pulse is rapid and slippery. This pattern often arises suddenly, driven by intense emotional upset or an acute illness that generates internal fire and phlegm.
A deficiency pattern emerges when the mind loses its anchor from prolonged strain, poor nutrition, or chronic illness. The person is anxious, easily startled, fatigued, with palpitations and poor appetite. The tongue is pale and the pulse is thin and weak. This type of delirium is more subdued, marked by mental clouding and a sense of being ungrounded rather than agitation.
In the context of a high fever, pathogenic heat can directly invade the pericardium, the protective layer around the heart. The person becomes acutely confused, delirious, and may have convulsions. The tongue is deep red and dry, and the pulse is rapid. This is a critical pattern seen in severe febrile illnesses, where the heat has bypassed the body's usual defenses.
After prolonged fire or illness has damaged yin fluids, residual empty-heat agitates the mind. The person may be irritable, restless, and have a flushed face in the afternoon, with a thin body and a red tongue with little coating. The pulse is thin and rapid. This quieter, wasting type of delirium often appears in later stages, when the body is depleted but still simmering with heat.
TCM Patterns for Delirium
In TCM, the aim is to address the root cause, not just the symptom — it calls that root cause a “pattern.” The same delirium 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 common to see a bit of yourself or a loved one in more than one pattern. Delirium rarely fits neatly into one box, especially because phlegm and fire can coexist, and deficiency can underlie an acute flare. The key is to notice what is dominant: is the person withdrawn and drowsy, or agitated and shouting? Is there a high fever, or is this a slow decline? These clues help separate the patterns.
Overlap is particularly common between Phlegm Misting the Heart and Phlegm-Fire harassing the Heart, as phlegm can transform into fire when stagnation persists. Similarly, chronic Heart and Spleen Deficiency can create a vulnerability where a sudden infection triggers Heat invading the Pericardium. A professional can untangle these layers by examining the tongue and pulse and tracing the timeline of symptoms.
Because delirium can signal a serious underlying condition-such as a severe infection, metabolic disturbance, or advanced organ failure-it is never a symptom to self-treat. If you suspect a pattern like Heat invading the Pericardium or Phlegm-Fire harassing the Heart, seek emergency medical care. Even for milder, chronic presentations, a TCM practitioner’s diagnosis ensures the right herbs and acupuncture are used, as some formulas are strong and require precise differentiation.
If you are using the Me & Qi pattern quiz and your result feels mixed, pay attention to the strongest feature: the presence or absence of fever, the energy level (agitated vs. lethargic), and the tongue appearance. These three factors often point clearly toward one pattern. But always consult a qualified practitioner, especially when consciousness is altered.

Formulas traditionally used for delirium
7 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 used to clear Phlegm and restore harmony between the Gallbladder and Stomach. It is commonly used for people experiencing insomnia, anxiety, restless sleep with vivid dreams, dizziness, nausea, or heart palpitations caused by Phlegm and stagnant Qi disturbing the mind. Despite its name ("Warm the Gallbladder"), the formula's overall effect is gently clearing and calming rather than warming.
A classical formula used to clear Heat and resolve Phlegm that is disturbing the mind and digestive system. It is commonly used for insomnia, restlessness, nausea, and a bitter taste in the mouth caused by the accumulation of Phlegm-Heat in the Gallbladder and Stomach. Think of it as a formula that calms both an agitated mind and an upset stomach by addressing the underlying combination of inflammatory Heat and sticky Phlegm.
A classical formula for calming severe mental agitation, mania, and emotional disturbances caused by an accumulation of internal Heat and Phlegm disturbing the mind. It uses heavy mineral substances to anchor and settle the spirit while clearing Heat and dissolving Phlegm from the Heart and Liver. Commonly applied in cases of acute psychiatric episodes, severe insomnia with agitation, and epilepsy related to Phlegm-Fire patterns.
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 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 renowned emergency formula used for severe febrile illnesses where extreme heat invades the Pericardium, causing loss of consciousness, high fever, delirium, and convulsions. It is one of the most famous TCM rescue medicines, historically described as capable of 'saving the critically ill in an instant.' This is a powerful prescription for acute crises and is not suitable for daily use or prevention.
A classical formula that nourishes the body's cooling Yin fluids while clearing excess internal heat. It is commonly used for symptoms such as hot flashes, night sweats, tinnitus, sore throat, dry mouth, and low back aching that arise when the Kidneys become depleted and the body overheats from within. It builds on the famous Liu Wei Di Huang Wan (Six Ingredient Rehmannia Pill) with two additional cooling herbs.
Acute patterns like Heat invading the Pericardium or Phlegm-Fire harassing the Heart often respond within days when treated promptly with herbs and acupuncture alongside conventional care. Chronic patterns rooted in deficiency, such as Heart and Spleen Deficiency or Yin Deficiency with Empty-Heat, may take several weeks to months to rebuild the body's reserves and stabilize the mind. Because delirium is a serious symptom, any complementary treatment plan must be coordinated closely with the patient's medical team.

Audience-specific guidance — open what applies to you
Delirium during pregnancy is a medical emergency, often signaling severe preeclampsia, infection, or metabolic crisis. In TCM, the most likely pattern is Heat invading the Pericardium, which requires urgent Western medical intervention alongside cautious herbal support. Many classic formulas for acute delirium - such as An Gong Niu Huang Wan or Sheng Tie Luo Yin - contain heavy, settling minerals and strong cold herbs that may be contraindicated in pregnancy.
Acupuncture can be a safer adjunct, but points traditionally forbidden in pregnancy, including LI4, SP6, BL60, and lower abdominal points, must be strictly avoided. Any herbal treatment must be guided by an experienced practitioner, with preference given to mild, cooling herbs like Zhu Ye or Lian Zi Xin, and only after the acute danger has passed.
When a breastfeeding mother experiences delirium, treatment must consider both the urgency of her condition and the safety of the infant. Bitter-cold herbs like Huang Lian and Da Huang, often used to clear Heat and Phlegm-Fire, can pass into breast milk and cause infant diarrhea or digestive upset. Milder alternatives such as Zhu Ru or Dan Dou Chi may be substituted where appropriate.
Acupuncture is generally safe during breastfeeding and can help calm the mind without exposing the infant to medication. Points like Shenmen HT-7 and Neiguan PC-6 can be used to settle the Shen. However, any acute delirium warrants immediate medical evaluation, and TCM treatment should be integrated with, not replace, standard emergency care.
In children, delirium most often appears as a complication of high fever, especially during acute infectious diseases. The pattern is almost always Heat invading the Pericardium, presenting as febrile convulsions followed by confusion or unconsciousness. Children's immature digestive systems also make them prone to Phlegm-Fire from food stagnation, which can suddenly cloud the mind.
Herbal dosages must be reduced according to age and weight - typically one-quarter to one-half the adult dose for young children. Acupuncture can be challenging in an agitated child, so acupressure at points like Baihui DU-20 and Yongquan KI-1 is often used instead. Immediate fever management and medical attention are paramount; TCM plays a supportive role in clearing Heat and reviving consciousness.
Elderly patients are particularly vulnerable to delirium, and TCM patterns in this age group often involve underlying deficiency. Heart and Spleen Deficiency is common, where chronic illness and poor nutrition leave the mind unanchored, producing a quiet, foggy confusion. Phlegm Misting the Heart is also frequent, as aging weakens the Spleen's ability to transform fluids, leading to phlegm accumulation that clouds the mind.
Treatment must be gentle and nourishing. Strong purging or cold herbs can further damage the Spleen and Stomach Qi. Herbal dosages are typically reduced to two-thirds of the adult dose. Acupuncture is well tolerated, but points should be needled with lighter stimulation. Polypharmacy is a major concern - many elderly patients take multiple medications, and herb-drug interactions must be carefully screened. Recovery is often slower, and treatment focuses on rebuilding Qi and Blood over weeks rather than days.
Evidence & references
The evidence base for TCM treatment of delirium is still developing. Most published studies are small, uncontrolled case series or retrospective chart reviews, often focusing on acupuncture for postoperative or intensive care unit delirium. A few systematic reviews suggest that acupuncture may reduce the incidence and duration of delirium, but the overall quality of evidence is rated as low due to risk of bias and small sample sizes.
Chinese herbal medicine for delirium, particularly in cancer patients, has been reported in Chinese-language journals with encouraging results, but rigorous randomized controlled trials are lacking. Given the acute and serious nature of delirium, TCM is best used as an integrative adjunct alongside standard medical care, and more high-quality research is needed to define its role clearly.
Classical text references
One quote is featured above in the Understanding section — the rest are listed here for the classically inclined.
「二症之因，或大怒而動肝火，或大驚而動心火，或痰為火升，升而不降，壅塞心竅，神明不得出入，主宰失其號令，心反為痰火所役。」
"The causes of these two conditions [quiet withdrawal and manic agitation] are either great anger stirring Liver Fire, or great fright stirring Heart Fire, or phlegm rising with fire and failing to descend, obstructing the heart orifices so that the spirit cannot enter or exit, the master loses command, and the heart is instead enslaved by phlegm-fire."

Frequently asked questions
Common questions about using Traditional Chinese Medicine for delirium.
Yes, acupuncture can be a powerful supportive tool. Points like Baihui (DU-20), Shenmen (HT-7), and Neiguan (PC-6) are used to calm the mind and clear orifices. In acute settings, even a single session may help reduce agitation and improve orientation. However, acupuncture is never a substitute for emergency medical evaluation - it works best as part of a comprehensive plan that addresses the underlying cause of the delirium, such as infection or metabolic imbalance.
For acute, heat-based patterns, herbal formulas like An Gong Niu Huang Wan or Qing Ying Tang can bring noticeable improvement in mental clarity within a day or two when the pattern is correctly identified. For phlegm-dominant patterns, it may take 3-7 days to see the fog lift. In chronic deficiency states, improvement is gradual - often 2-4 weeks before the mind feels steadier and less prone to confusion. Consistency with herbs and addressing the root cause are key.
This must be managed carefully. Many delirium patients are on multiple medications, including sedatives, antibiotics, or blood thinners. Some herbs, such as Dang Gui (Angelica sinensis) or Dan Shen (Salvia miltiorrhiza), can interact with anticoagulants. Always give your TCM practitioner a complete list of your medications, and inform your doctor that you are using herbs. Never stop prescribed medications without medical supervision. In an inpatient setting, herbal treatment should only be given with the hospital team's knowledge.
TCM always aims to treat the root. For example, if delirium is caused by phlegm-fire, the herbs will clear heat and transform phlegm - the very factors generating the confusion. If it stems from Heart and Spleen deficiency, the formula will tonify Qi and Blood to anchor the mind. By addressing the underlying imbalance, TCM not only helps resolve the current episode but also strengthens the body against future occurrences, especially in vulnerable individuals.
In general, avoid greasy, fried, and dairy-heavy foods that create phlegm, as well as spicy and alcohol that stir up fire. Favor warm, easily digested meals like congee, steamed vegetables, and light broths. For deficiency patterns, nourishing soups with ingredients like Chinese yam, lotus seeds, and goji berries can help rebuild Qi and Blood. For heat patterns, cooling foods like mung beans, cucumber, and pear are beneficial. Specific advice will depend on the individual pattern.
Yes, TCM can be used proactively. For an elderly person with Spleen deficiency who is prone to phlegm, pre-operative acupuncture and herbs that strengthen digestion and resolve phlegm may reduce the risk of post-operative delirium. Similarly, someone with Yin deficiency might receive nourishing herbs to prevent empty-heat from flaring under the stress of illness. This preventive approach is an area of growing interest and should be discussed with both the surgical and TCM teams.
