Quick answer: Allergies happen when the immune system overreacts to harmless substances such as pollen, dust or pet dander. Simple habits such as nasal saline rinses, HEPA filters and showering after outdoor time reduce exposure. Quercetin, stinging nettle, vitamin C, butterbur and probiotics are commonly used natural supports, often started a few weeks before allergy season.
Why allergies happen
The immune system mistakes a harmless protein for a threat and releases histamine and other chemicals from mast cells. Gut health, inflammation, genetics and how well your body clears histamine all play a role.
Habits that reduce symptoms
- Rinse your nose with saline once or twice daily
- Use a HEPA air filter and keep windows closed on high-pollen days
- Shower and change clothes after time outdoors
- Start your plan a few weeks before your season
Natural supports commonly used
- Quercetin with bromelain: helps stabilize mast cells
- Stinging nettle leaf: traditionally used for hay fever
- Vitamin C: has mild antihistamine effects
- Butterbur: studied for hay fever; use only PA-free products
- Probiotics: may help balance immune responses
- Omega-3s: support a healthy inflammatory response
- Spirulina: studied for allergy symptoms
- Local honey: popular, though evidence is limited
Amounts should be individualized. If you work with me, the products I use are in my Fullscript dispensary.
Is testing helpful?
Allergy testing (skin or blood IgE) identifies specific triggers. In chronic cases, gut and inflammation markers can add context. Functional labs are optional. They can be helpful in more complex cases, and in my practice they are available only to patients working 1-on-1 with me.
Allergies and healthy aging
Ongoing allergic inflammation adds to the body’s overall inflammatory load and oxidative stress, and it reflects disrupted communication within the immune system. Calming it supports long-term health. Related: supporting your immune system and gut barrier support.
When to see a naturopathic doctor
- Seasonal or year-round allergies that affect sleep or daily life
- You want to rely less on allergy medications
- You have allergies along with gut or skin issues
- Your child has allergies and you want gentle options (with their pediatrician)
See a medical provider promptly or call 911 for trouble breathing, swelling of the lips, tongue or throat, or hives with dizziness. These can be signs of anaphylaxis.
