Pulmonary Edema

What is Pulmonary Edema?

Pulmonary edema is an abnormal buildup of fluid in the lung tissue and air sacs, which reduces gas exchange and can lead to respiratory failure.^[1] It can be life-threatening and needs emergency medical care. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

Common symptoms

The main symptoms are increasing shortness of breath, abnormal crackling sounds in the lungs on examination and falling oxygen levels.^[1] People often feel more breathless lying flat, and may cough up frothy or pink-tinged sputum, wheeze, breathe rapidly and feel anxious or restless. A bluish tint to the lips or skin signals low oxygen and is an emergency.^[2]

Causes and risk factors

Pulmonary edema is either cardiogenic, from the heart being unable to clear blood from the lung circulation, or non-cardiogenic, from direct injury to the lungs.^{[1, 3]} Cardiogenic causes include heart failure, heart attack, valve disease and abnormal heart rhythms, and any heart condition that raises pressure on the left side of the heart can cause it.^[2]

Non-cardiogenic causes include acute respiratory distress syndrome (ARDS), a severe inflammatory lung injury that can follow infection, trauma or inhaled toxins.^[4] Kidney failure, rapid ascent to high altitude and severe pneumonia are other recognized causes.^[1]

How it is diagnosed and treated conventionally

Doctors diagnose pulmonary edema from your history, a physical examination, and tests such as chest imaging, lung ultrasound, an echocardiogram and natriuretic peptide blood levels.^[2] Identifying the type matters because it determines treatment.^[2]

Treatment is given urgently and depends on the cause. Non-invasive ventilation is considered early, and diuretics and vasodilators are used to relieve congestion in the lungs.^[2] The heart condition behind it then needs ongoing care. In acute heart failure, treatment is mostly aimed at relieving congestion, and readmission to hospital remains common.^[5]

Why Pulmonary Edema calls for a whole-person approach

Pulmonary edema is a sign of another problem, so lasting management means looking after the heart, kidneys and lungs, and the person living with them. The medical team treats the cause. Supportive care, if used at all, addresses how a person copes during and after recovery.^{[1, 5]}

The heart and circulation

Most cardiogenic pulmonary edema comes from raised pressure on the left side of the heart.^[2] In acute heart failure, symptoms and signs mostly reflect congestion, and the underlying heart disease and the triggers for a flare vary widely between people.^[5] This is why ongoing cardiology follow-up matters.

Fluid balance and the kidneys

Kidney failure can cause the body to retain fluid and lead to pulmonary edema.^[1] Fluid balance is therefore managed by your physicians, not through diet or herbs chosen on your own.

Anxiety and stress

Breathlessness is frightening, and anxiety and fatigue are common in people living with heart failure. In a systematic review of 24 trials of mind-body approaches such as Tai Chi, yoga and relaxation in heart failure, nearly all reported small to moderate gains in quality of life, depression, anxiety and fatigue.^[6] These are the symptom-level areas where supportive care may help.

Acupuncture as supportive care in Pulmonary Edema

What the research shows

No clinical trials of acupuncture for pulmonary edema itself were found. The closest evidence is for heart failure, the most common cause, and it is limited and inconclusive.

A systematic review of seven randomized trials of acupuncture in heart failure found most had considerable methodological flaws. In one acute heart failure trial, acupuncture shortened intensive care stay and lowered readmission, but mortality was not affected. In chronic heart failure, trials reported better exercise capacity and quality of life. The authors concluded that effectiveness remains inconclusive.^[7]

A 2024 meta-analysis of eight trials combining acupuncture and herbal medicine with standard care found better heart function measures and quality-of-life scores than standard care alone. Because acupuncture and herbs were given together, it cannot separate their effects.^[8] A 2025 meta-analysis of 22 trials of moxibustion alongside standard care reported better clinical response and exercise capacity, and called for larger trials with standard methods.^[9]

An umbrella review of integrative medicine for chronic heart failure found low to very low certainty evidence that acupuncture may improve BNP, a blood marker of heart strain, and concluded that evidence for most such approaches is limited.^[10]

How acupuncture may work

The proposed explanations are speculative, and none has been shown to apply to pulmonary edema. The heart failure studies measured changes in hemodynamic measures, heart rate variability and a heart strain marker, but the reviews do not establish how any such change would occur.^[7]

What treatment involves

Acupuncture is considered only once your condition is under medical management and your physicians know about it. It uses fine, sterile, single-use needles, usually left in place for about 20 to 40 minutes, with a short course of visits and reassessment. Our aim is to support relaxation, sleep and comfort, not to treat fluid in the lungs.

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[11] Tell the practitioner first if you have a pacemaker or implanted defibrillator (relevant to electroacupuncture), take blood thinners, or have a bleeding disorder.

Ayurvedic medicine as supportive care in Pulmonary Edema

The Ayurvedic view

Ayurveda has no classical diagnosis that matches pulmonary edema. Breathlessness is traditionally described under Shvasa and heart conditions under Hridroga, and fluid retention is traditionally linked to Kapha and sluggish digestion and metabolism (agni). These are traditional frameworks, not biomedical diagnoses, and they do not replace emergency assessment.

Therapies that may be used

For a person who is medically stable, care is individualized and usually gentle:

• Regular, light, warm meals and steady sleep and rest routines, within any salt and fluid limits set by your physicians
• Gentle breathing practices and relaxation, if your physicians agree
• Individually prescribed herbs only after your cardiology team has reviewed them, because many herbs affect blood pressure, fluid balance and heart medicines

Panchakarma procedures such as induced vomiting, purging or medicated enemas are not appropriate here. They can shift fluid and electrolytes and are unsuitable during acute illness, with heart or kidney disease, or in frailty, so they are not appropriate for this condition.

What the research shows

No clinical trials of Ayurvedic medicine for pulmonary edema were found, and we did not find reliable trials of Ayurvedic treatment for heart failure either. Any benefit is therefore unknown. A review of mind-body approaches in heart failure included yoga trials and reported small to moderate gains in quality of life and mood, which is relevant to gentle breathing and relaxation practices but is not evidence for Ayurvedic herbs.^[6] An umbrella review found the benefit of yoga in heart failure was unclear.^[10]

Herbal medicine as supportive care in Pulmonary Edema

Herbs and formulas that have been studied

No trials of herbal medicine for pulmonary edema itself were found. In heart failure, the most studied example is Oryeongsan, a traditional East Asian formula used to manage fluid imbalance, and other formulas given by mouth or by injection in China.^{[10, 12]}

What the research shows

The evidence is limited. A meta-analysis of 59 trials with 5,069 participants found that adding Oryeongsan or its variants to standard heart failure care improved heart function and other measures compared with standard care alone, with no significant difference in adverse events. When compared with standard care plus placebo, the improvements in ejection fraction and overall effectiveness were not significant, and the authors called for further validation.^[12]

An umbrella review judged intravenous Chinese herbal medicines as possibly improving BNP, on low to very low certainty evidence, and found that vitamin E may increase hospitalization in heart failure and should be avoided.^[10] None of these studies tested herbs as a treatment for fluid in the lungs during an acute episode.

Safety and herb-drug interactions

People with heart and lung disease usually take several medicines, so herb-drug interactions are the main concern. Reported interactions include bleeding when warfarin is combined with herbs such as ginkgo, danshen, dang gui, ginger and garlic, and raised digoxin levels with Siberian ginseng.^{[13, 14]} Tell us about every medicine you take, including diuretics, blood thinners and heart rhythm drugs, and never add a herb without your cardiologist's review.

Product quality also matters. In one study, about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[15] Tell us if you are pregnant or breastfeeding, or have kidney or liver disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine describes fluid retention and breathlessness through ideas such as impaired movement and transformation of fluids by the lung, spleen and kidney, and an Oryeongsan-type formula is traditionally used for fluid imbalance.^[12] In biomedical terms, researchers instead measure pressure in the heart and lung circulation, congestion and heart strain markers.^{[2, 5]}

Ayurveda's Kapha excess and weak agni describe heaviness, retained fluid and breathlessness. No study has shown that a dosha corresponds to a specific biological process, and these ideas offer no way to treat acute pulmonary edema.

How this care fits with your medical care

Pulmonary edema needs medical treatment, and our care is supportive only. Keep your physician, cardiologist or pulmonologist, and do not stop or change prescribed medicines, oxygen, diuretics or follow-up testing without your prescriber. We do not diagnose pulmonary edema or manage fluid balance.

Complementary care is considered only after your condition is under medical management. Bring your diagnosis, a recent discharge summary or test results, and a full list of medicines and supplements. We ask that your treating team knows you are receiving complementary care.

When to seek urgent medical care

Pulmonary edema can progress within minutes to hours and should be treated as an emergency.^{[1, 2]}

• Sudden or rapidly worsening shortness of breath, especially when lying flat or waking at night gasping
• Coughing up frothy, pink or blood-tinged sputum
• Blue or gray lips or skin, or confusion
• Chest pain or pressure, fainting, or a very fast or irregular heartbeat
• Rapid weight gain with new leg or abdominal swelling in someone with heart failure
• Breathlessness after a rapid climb to high altitude, smoke inhalation or severe infection

If any of these occur, call 911 or go to the nearest emergency department. Do not wait for an appointment or try to treat it with herbs or acupuncture.
