Hives

What is Hives?

Hives (urticaria) are itchy welts, called wheals, that appear on the skin, sometimes with deeper swelling called angioedema. They happen when mast cells in the skin release histamine and other substances.^[1] Up to 20% of people have hives at some point in life.^{[1, 2]}

Common symptoms

The main symptoms are raised, itchy welts that can be red or skin-colored, and that often fade within hours while new ones appear elsewhere.^[1]

• Welts of varying size and shape that move around the body
• Itching, which may be intense
• Angioedema, which is swelling of deeper skin layers, most often around the eyes, lips, hands or feet
• Welts that leave no scarring when they clear

Swelling that involves the throat or tongue can block the airway and is an emergency.^[3]

Causes and risk factors

Acute urticaria lasts 6 weeks or less and is often linked to infections, drugs or foods. Chronic urticaria lasts longer than 6 weeks and is either spontaneous, with no single trigger, or inducible, with definite triggers such as cold, pressure, heat or sunlight.^[1]

In chronic spontaneous urticaria, which affects about 1% of people, autoantibodies that activate mast cells are involved in more than half of cases. It is most common in women aged 30 to 50 and often lasts more than a year.^[4]

How it is diagnosed and treated conventionally

Diagnosis is clinical, based on your history and the appearance of the welts. Tests may be used to exclude other conditions and to find triggers in chronic hives.^[1] Allergy testing is useful when a specific allergic trigger is suspected.

Second-generation antihistamines are first-line treatment, and about 40% of people with chronic spontaneous urticaria respond well. Omalizumab (an anti-IgE antibody) is the second-line medicine, and cyclosporine is a third-line option with possible side effects on kidney function and blood pressure.^{[2, 4]} Avoiding known triggers also helps.^[1]

Why Hives calls for a whole-person approach

Chronic hives are more than a skin reaction. The immune system, the nervous system and emotional state all interact, and the condition can affect sleep, mood and daily life.

Medical treatment aims to control the immune and mast cell activity. Complementary care is aimed at the surrounding factors that affect how a person feels and copes.

Immune activity and autoimmunity

Chronic spontaneous urticaria is often driven by autoimmune mechanisms, and it is associated with autoimmune thyroiditis in about 20% of patients.^[4] This is one reason a physician's evaluation matters.

Itch and nerve signaling

Persistent itch can sensitize the nervous system and feed an itch-scratch cycle in chronic hives. Nerve signaling and mast cells interact in this process.^[5]

Stress, anxiety and mood

Psychological factors such as stress, anxiety and depression can make chronic hives worse, and they are linked to changes in the body's stress-response systems.^[5] Anxiety affects about 10% to 31% of people with chronic spontaneous urticaria, and depression about 7% to 29%.^[4]

Quality of life

About 40% of people with chronic spontaneous urticaria report a very large or extremely large effect on quality of life.^[4] Sleep loss from nighttime itch is a common part of this burden.

Acupuncture for Hives

What the research shows

Research suggests acupuncture may reduce symptoms of chronic spontaneous urticaria, but the effect found so far is small. We found no acupuncture trials for acute hives.

The largest trial randomly assigned 330 people with chronic spontaneous urticaria in China to acupuncture, sham acupuncture or a waitlist for 4 weeks. Symptom scores fell by 8.2 points with acupuncture, 4.1 with sham and 2.2 with waitlist. The difference from sham did not reach the threshold for a clinically important change. Mild, short-lived side effects occurred in about 14% of the acupuncture group. The trial did not allow antihistamines and was not fully blinded.^[6] A smaller sham-controlled pilot of 80 people found a trend toward benefit that was not statistically significant.^[7]

A 2025 meta-analysis of 6 trials with 615 participants found 4 weeks of acupuncture lowered urticaria activity, improved quality of life and sleep, and eased anxiety and depression scores compared with sham or no acupuncture. It also found more bruising under the skin.^[8] Another 2025 meta-analysis of 8 trials with 564 participants found acupuncture better than antihistamines on several measures, but rated the certainty of evidence as low.^[9] Earlier reviews of Chinese trials also found benefit over antihistamines alone or as an add-on to medication. One rated the evidence as low level with high risk of bias, and the other called for higher-quality studies.^{[10, 11]}

How acupuncture may work

How acupuncture might affect hives is not settled. Some trials in the 2025 review reported lower IgE and interleukin-4 levels and higher interferon-gamma levels with acupuncture, which hints at an effect on immune signaling.^[9] These are proposed explanations from small studies, not settled mechanisms.

What treatment involves

Treatment uses fine, sterile, single-use needles placed at points on the arms, legs and body, usually left in place for about 20 to 40 minutes. The pilot trial gave 5 sessions a week for 2 weeks, while the larger trial treated for 4 weeks.^{[6, 7]} We reassess after a short course of visits.

Serious problems are rare. In prospective studies about 9 in 100 patients had a minor reaction such as brief bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[12] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Hives

The Ayurvedic view

Ayurveda compares hives to Shitapitta (also spelled Sheetapitta), a condition described as an imbalance of the doshas that is treated with purification procedures.^[13] This is a traditional framework, not a biomedical diagnosis.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine adjusted to the person, such as avoiding foods one has noticed trigger hives
• Herbs prescribed individually, taken by mouth or applied to the skin
• Panchakarma procedures such as Vamana (therapeutic emesis) and Virechana (medicated purging), where traditionally appropriate^{[13, 14]}

Panchakarma is not appropriate during pregnancy, acute illness, frailty, or while swelling of the lips or throat is present, and should only follow a medical evaluation. Herbal preparations applied to the skin (transdermal medication therapy) may be considered, but a new product can itself cause hives, so skin reactions should be watched closely.

What the research shows

The research on Ayurveda for hives is very limited, and we found no randomized trials. The published reports are two single case reports of people with chronic spontaneous urticaria who had not responded to conventional treatment and who were treated with Panchakarma procedures plus internal medicines. Both reported large improvements in symptom scores.^{[13, 14]} A single case cannot show that a treatment caused the improvement, and hives can fluctuate and settle on their own.

Herbal medicine for Hives

Herbs and formulas that have been studied

Most research is on Chinese herbal formulas. One that has been pooled in a meta-analysis is Xiaofeng powder, which TCM uses for wind-related rashes.^[15] A review of Asian herbal medicine for chronic urticaria describes the herbs commonly used and their proposed anti-allergic and anti-inflammatory actions.^[16]

What the research shows

The evidence is limited and the trials are of low quality. A 2024 meta-analysis of 11 trials with 1,076 patients found modified Xiaofeng powder gave higher response rates and lower recurrence than antihistamines. The authors said the included trials were of relatively low quality and need confirmation.^[15] An umbrella review of 41 systematic reviews of treatments for chronic urticaria found that most reported positive results, but the methods and evidence quality were generally poor.^[17]

Safety and herb-drug interactions

Herbs can cause allergic reactions, including hives. For example, turmeric's active compound curcumin has been reported to cause contact urticaria.^[18] A new herb or skin product should be introduced one at a time.

Herbs can also interact with medicines, including blood thinners and immune-suppressing drugs. St John's wort, for example, has been reported to lower ciclosporin levels, which matters for people using cyclosporine for hives.^[19] In one study, about one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, have liver or kidney disease, or take omalizumab, cyclosporine or any prescription medicine.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine attributes sudden, itchy, shifting wheals to wind, and often to wind combined with heat, damp or blood deficiency.^[15] Researchers instead study mast cell activation, autoantibodies and immune signaling molecules such as IgE and interleukins.^{[1, 9]}

Ayurveda's Shitapitta describes itchy, raised rashes as an imbalance of the doshas.^[13] No study has shown that a dosha or a pattern corresponds to a specific immune process.

How this care fits with your medical care

Integrative care for hives is complementary. Keep seeing your physician, allergist or dermatologist, keep taking prescribed antihistamines and other medicines as directed, and do not stop or change them without your prescriber. We do not diagnose the cause of hives, and new or severe hives should be medically evaluated.

Please bring your diagnosis, any allergy or blood test results, a full list of medicines and supplements, and a record of when hives appear and what you were doing or eating.

When to seek urgent medical care

Hives can be the first sign of a severe allergic reaction, and swelling of the airway can be life-threatening.^[3]

• Swelling of the lips, tongue, face or throat
• Trouble breathing, wheezing, a tight throat or a hoarse voice
• Dizziness, fainting or a racing heartbeat with hives
• Hives that appear within minutes of a sting, a food or a new medicine
• Repeated vomiting or severe abdominal pain with hives or swelling
• Individual welts that last more than a day, are painful or leave bruising, or hives with fever and joint pain

If any of these occur, call 911 or go to the nearest emergency department.
