Histamine intolerance is a condition that can cause a wide array of uncomfortable symptoms, from headaches and hives to digestive issues and fatigue. Unlike a traditional allergy, histamine intolerance results from an accumulation of histamine in the body, often due to the inability to break it down efficiently. While antihistamines are commonly prescribed, many individuals seek natural remedies to manage their symptoms with fewer side effects and better long-term health outcomes.
Understanding histamine intolerance and the natural ways to support the body’s detoxification and enzyme production processes can provide a meaningful path to relief. This comprehensive guide explores evidence-based natural remedies, dietary strategies, lifestyle modifications, and supplements that may help minimize histamine intolerance symptoms and improve overall well-being.
What Is Histamine Intolerance?
Histamine is a naturally occurring compound involved in the immune system, digestion, and central nervous system. In healthy individuals, enzymes like diamine oxidase (DAO) and histamine-N-methyltransferase (HNMT) break down histamine efficiently. However, when histamine levels exceed the body’s ability to degrade it, symptoms can arise.
Common symptoms include:
- Skin flushing, rashes, or hives
- Nasal congestion
- Headaches or migraines
- Bloating and digestive issues
- Fatigue and irritability
Histamine intolerance is often confused with food allergies or sensitivities. For a detailed breakdown of the condition, Cleveland Clinic offers an in-depth explanation.

Dietary Approaches to Reduce Histamine Load
One of the most effective natural strategies for managing histamine intolerance is through diet. Reducing high-histamine foods and focusing on fresh, whole ingredients can significantly lower histamine levels in the body.
High-Histamine Foods to Avoid
- Aged cheeses
- Cured meats
- Fermented foods (sauerkraut, yogurt, kombucha)
- Alcohol, especially red wine
- Vinegar-containing foods (pickles, ketchup)
Low-Histamine Foods to Include
- Fresh meat and poultry
- Eggs
- Gluten-free grains like rice and quinoa
- Leafy greens, zucchini, and cucumbers
- Blueberries, apples, and pears
Natural Supplements That Support Histamine Breakdown
Natural supplements can play a significant role in managing symptoms by supporting enzyme activity, gut health, and reducing inflammation.
DAO Enzyme Supplements
DAO (diamine oxidase) supplements provide the enzyme directly to help break down dietary histamine. These are particularly helpful before meals containing higher histamine levels.
Quercetin
A potent natural antihistamine, quercetin stabilizes mast cells and reduces histamine release. Found in apples, onions, and capers, it is also available in capsule form.
Vitamin C
Vitamin C can help degrade histamine and support the immune system. According to Healthline, regular supplementation may lower blood histamine levels.
Probiotics (Selective Strains)
While many probiotics increase histamine, strains such as Lactobacillus rhamnosus and Bifidobacterium infantis are considered histamine-neutral or degrading. For a probiotic guide, Dr. Axe provides a breakdown.

Gut Health and Histamine Intolerance
A healthy gut plays a crucial role in histamine metabolism. Dysbiosis, or imbalance of gut flora, can impair DAO production and lead to increased histamine levels.
How to Support Gut Health
- Eat fiber-rich, whole foods
- Use selective probiotics
- Avoid overuse of antibiotics
- Incorporate bone broth and fermented (low-histamine) foods cautiously

Herbal Remedies for Histamine Relief
Several herbs may naturally reduce histamine levels or support the immune system without suppressing its function entirely.
Stinging Nettle
This herb is a natural antihistamine that can ease nasal congestion and allergic symptoms. It is commonly used in tea or capsule form.
Butterbur
Shown to reduce inflammation and alleviate headaches and hay fever, butterbur is widely used in Europe for histamine-related symptoms.
Turmeric
With its anti-inflammatory and antioxidant properties, turmeric may help manage histamine intolerance by reducing systemic inflammation.
Use herbal remedies with guidance from a qualified practitioner, especially if taking other medications.
Lifestyle Adjustments for Managing Symptoms
Managing stress, sleep, and environmental triggers is essential for those with histamine intolerance.
Stress Reduction
Chronic stress elevates cortisol, which can destabilize mast cells. Practices such as yoga, meditation, and nature walks help balance the nervous system.
Environmental Allergen Control
Dust mites, mold, and pollen can aggravate histamine intolerance. Use HEPA filters, keep windows closed during high pollen seasons, and clean living spaces regularly.
Regular Movement
Gentle exercise supports circulation and detoxification. Opt for activities like swimming, walking, or Pilates.
When to Seek Professional Help
Histamine intolerance symptoms can overlap with other conditions such as mast cell activation syndrome (MCAS), allergies, or gastrointestinal diseases. Consulting with a functional medicine doctor or allergist can help tailor a comprehensive care plan.
