Urticaria

What is Urticaria?

Urticaria is an inflammatory skin condition in which mast cells in the skin release histamine and other chemicals, causing itchy wheals (hives), swelling under the skin (angioedema), or both.^[1] Up to 1 in 5 people have an episode at some point in life.^[1]

Common symptoms

The main symptom is raised, itchy welts of varying size that appear and fade, often in different places from one day to the next.^[1] Some people also have angioedema, a deeper swelling that often affects the lips or eyelids.^[2]

Chronic urticaria affects quality of life, and it is linked with poor sleep, anxiety and low mood.^{[1, 3]}

Causes and risk factors

Acute urticaria lasts 6 weeks or less and can be linked to infections, medicines or foods.^[1] Chronic urticaria lasts longer than 6 weeks and is either spontaneous (no outside trigger) or inducible (set off by a specific trigger such as cold, pressure or heat).^[1]

In chronic spontaneous urticaria, more than half of people have autoimmune forms in which antibodies activate mast cells. It is most common in women aged 30 to 50 and is often associated with autoimmune thyroid disease.^[3]

How it is diagnosed and treated conventionally

Urticaria is diagnosed from the history and the appearance of the skin. Tests are used to rule out other conditions or to look for causes in chronic cases.^[1]

Treatment follows steps. Second-generation H1 antihistamines come first, omalizumab is the usual second step, and cyclosporine is a third option.^{[2, 3]} About 40% of people with chronic spontaneous urticaria respond well to antihistamines, and at least 30% do not respond enough to omalizumab.^[3]

Why Urticaria calls for a whole-person approach

Hives are driven by mast cell activation, but several other factors can influence how often they flare and how much they affect daily life. Chronic urticaria lasts more than a year in most people, so symptom control, sleep and stress become part of the picture.^[3]

Care that addresses these factors alongside medical treatment is a reasonable addition, as long as the medical side is in place.

Immune activity and autoimmunity

Autoantibodies, complement and coagulation pathways are all involved in how chronic spontaneous urticaria develops.^[1] This is why a physician's evaluation, including a check for autoimmune thyroid disease, matters before anything else.^[3]

Stress and the nervous system

A systematic review of 13 human studies noted that some people with chronic urticaria report a significant stressor before onset, and that nerve signals, stress hormones and skin immune cells appear to interact. Whether stress causes urticaria or only worsens it is still unclear.^[4]

Anxiety, depression and sleep

A meta-analysis of 12 observational studies found that people with chronic urticaria had higher odds of anxiety and depression than others.^[5] Itch and poor sleep can feed each other, so mood and sleep are worth addressing along with the skin.

Acupuncture for Urticaria

What the research shows

Acupuncture may reduce symptoms in chronic spontaneous urticaria, but the effect in the best trial was small. In a three-hospital Chinese trial of 330 people, acupuncture lowered the weekly urticaria activity score more than sham acupuncture or no treatment over 4 weeks. The authors said the difference did not reach the threshold for a clinically important change. Participants could not use antihistamines during the trial, mild or brief side effects were more frequent with acupuncture, and follow-up was short.^[6]

A 2025 meta-analysis of 6 trials with 615 people found that 4 weeks of manual acupuncture, compared with sham or no acupuncture, improved urticaria scores, quality of life, sleep, anxiety and depression scores.^[7] A larger review of 18 studies with 1,829 patients found acupuncture was better than sham acupuncture or waitlist for urticaria scores. It found no clear difference when compared with medicines.^[8]

Another 2025 review of 8 trials found acupuncture beat antihistamines on response rate and recurrence, but it rated the certainty of the evidence as low and noted possible publication bias.^[9] An overview of 41 systematic reviews of treatments for chronic urticaria found the methods of many reviews were poor.^[10]

How acupuncture may work

How acupuncture might affect urticaria is not established. In pooled trials, acupuncture was associated with lower IgE and interleukin-4 levels and higher interferon-gamma, which suggests an effect on allergic immune signaling, but these are lab measures from low-certainty studies.^[9] Better sleep, mood and quality of life in the trials suggest effects on stress and sleep as well.^[7]

What treatment involves

Treatment uses fine, sterile, single-use needles at points on the arms, legs and body, usually left in place for about 20 to 40 minutes. The reviewed trials gave a course of several sessions over about 4 weeks, and we reassess after a short course of visits.^{[6, 7]}

Serious problems are rare. 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.^[11] One meta-analysis found more small bleeds under the skin with acupuncture.^[7] 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 Urticaria

The Ayurvedic view

Ayurveda describes a condition resembling urticaria as Sheetapitta, understood as an imbalance of the doshas, in which the body is described as responding to cold, damp or incompatible influences with itchy swellings, commonly involving Pitta and Kapha, sometimes with Vata.^[12] These are traditional categories used to plan care, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine, such as avoiding foods a person notices triggering hives and keeping regular meals and sleep
• Cooling, soothing external care for the skin, chosen to suit the person
• Herbs used traditionally in Ayurveda for itching and skin conditions, prescribed individually
• Panchakarma purification procedures in selected cases

Panchakarma is not appropriate during pregnancy, acute illness or frailty, and should be considered only after the diagnosis has been confirmed by a physician. Its emesis and purgation procedures are not part of every plan. We can also discuss whether a herbal preparation applied to the skin (transdermal therapy) is suitable, but no research supports it for urticaria.

What the research shows

The research on Ayurveda for urticaria is very limited. A PubMed search found no clinical trials and no systematic reviews. It found two single-patient case reports of chronic spontaneous urticaria that had not responded to conventional medicines. Both reported improvement after Panchakarma procedures plus internal medicines, with one describing complete remission.^{[12, 13]} A single case cannot show that a treatment caused the change, and chronic urticaria can fluctuate over time.

Herbal medicine for Urticaria

Herbs and formulas that have been studied

Chinese herbal formulas in trials are often given together with antihistamines.^[14] A review of 14 trials found the most often used herbs included saposhnikovia (windbreak), licorice, Chinese angelica (Angelica sinensis), schizonepeta, cicada slough and astragalus.^[15] Named formulas that have been studied include Xiaofeng powder, Danggui Yinzi, Yupingfeng powder and Guizhi decoction.^{[14, 16]}

What the research shows

The evidence is limited. A review of 14 trials with 1,192 patients found Chinese herbal medicine had a higher response rate than control treatment and lower recurrence, though symptom scores did not differ significantly and the authors noted shortcomings in how treatment effect was measured.^[15] A review of 11 trials of Xiaofeng powder reported better outcomes than antihistamines and fewer recurrences, but described the study quality as low.^[16]

A network analysis of 50 trials with 5,814 patients found that several classical formulas added to antihistamines were better than antihistamines alone. The certainty of evidence for efficacy was mostly moderate and for safety relatively low, and head-to-head trials are still needed.^[14]

Safety and herb-drug interactions

Herbs are active substances and can interact with medicines. Reported interactions include bleeding when warfarin is combined with danshen, and lower levels of ciclosporin with St John's wort, which has led to organ rejection.^[17] This matters here because cyclosporine is used for refractory urticaria, and people on it or other immune-suppressing drugs need a physician's review before taking any herb.^[3]

Herbal and dietary supplements account for about 20% of drug-induced liver injury in the United States.^[18] In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[19] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, or have liver or kidney disease. Some herbs can themselves cause allergic reactions, so report any new rash or swelling right away.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes hives as wind combined with heat, dampness or blood deficiency, and Ayurveda describes Sheetapitta as disturbed doshas.^{[12, 16]} Researchers studying urticaria measure different things: mast cell activation, autoantibodies, allergic immune signaling such as IgE and interleukin-4, and stress-nervous system-skin interactions.^{[1, 4, 9]}

The "wind" that comes and goes may loosely parallel wheals that move and fade. No study has shown that a traditional pattern corresponds to a specific biological process.

How this care fits with your medical care

Integrative care for urticaria is complementary. Keep your physician, allergist or dermatologist, and do not stop or change antihistamines, omalizumab, cyclosporine or any other prescribed treatment without your prescriber. We do not diagnose the cause of hives or manage the disease itself.

Please bring your diagnosis, any allergy or thyroid test results, a full list of medicines and supplements, and a record of when hives flare. Tracking flares with a symptom score can help your physician and us see whether anything is helping.

When to seek urgent medical care

Hives can sometimes be part of a serious allergic reaction, so some symptoms need emergency care.^[2]

• Swelling of the lips, tongue, face or throat
• Trouble breathing, wheezing or tightness in the chest
• Trouble swallowing or a hoarse voice
• Dizziness, fainting or a racing heartbeat with hives
• Hives that follow a new medicine, food or insect sting and spread quickly
• Hives that last several weeks without a medical evaluation

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