Food Allergies

Why it works: Mast-cell and basophil stabilization — quercetin reduces degranulation and histamine release, so it acts like a natural mast-cell stabilizer. This is a central reason it may reduce...

Instructions: Formulations used in trials. • Standard quercetin (aglycone) oral capsules — used in some trials at ~200 mg/day. European Review Examine. • “Phytosome” / lecithin-bound (bioavailab...

Warnings: Evidence-based cautions. • Pregnancy & breastfeeding: safety is not established — most authorities a...

Studies: Human clinical trials / systematic reviewsRandomized, double...

Why it works: Butterbur (Petasites hybridus) has credible evidence for treating allergic rhinitis (hay fever) and some asthma-related inflammation because constituents (chiefly petasin and relat...

Instructions: The clinical trials used standardized, PA-reduced / PA-free extracts (brand names in the literature include Ze339, Petadolex/Petasites extracts). Two typical regimens from publishe...

Warnings: Pyrrolizidine alkaloids (PAs): many butterbur plant parts naturally contain unsaturated PAs that are...

Studies: Clinical trials and post-marketing studies have shown benefi...

Why it works: Probiotics show promise — especially certain strains (eg. Lactobacillus rhamnosus GG and some multi-strain mixes) — for helping induce tolerance in some infant/child cow’s-milk all...

Instructions: Strains most commonly trialed. • Lactobacillus rhamnosus GG (LGG / ATCC 53103) — the most-studied single strain for cow’s-milk allergy. Frontiers SpringerLink. • Multi-strain mixes...

Warnings: Probiotics are widely used and generally well tolerated in healthy people, but important safety warn...

Why it works: Spirulina (Arthrospira/Limnospira) has some laboratory and clinical evidence for reducing allergic inflammation (most human trials are in allergic rhinitis or asthma), but there is...

Instructions: Allergic rhinitis (Cingi et al., double-blind randomized trial): 2,000 mg/day (given as five tablets daily) for 6 months. That study reported significant reductions in sneezing, na...

Warnings: Spirulina can itself be allergenic — rare but real anaphylaxis has been reported. Several case repor...

Studies: Human clinical / feeding studiesCingi C, Conk-Dalay M, Cakli...

Why it works: There is some biological plausibility and clinical evidence that stinging nettle (Urtica dioica) can reduce histamine-mediated symptoms (mostly allergic rhinitis/hay fever). Howeve...

Instructions: Freeze-dried leaf (acute symptomatic use): In the Mittman randomized study participants used ~300 mg freeze-dried nettle at onset of symptoms (single dose, used when symptoms appea...

Warnings: Allergic reactions to nettle: Paradoxically, nettle contact can cause urticaria / stinging and cases...

Studies: Allergic rhinitis / hay fever: Several small randomized tria...

Why it works: There is plausible mechanistic and some clinical evidence that glutamine helps intestinal barrier/immune function (which could reduce antigen exposure and downstream hypersensitivi...

Instructions: Most useful, evidence-based dosing from randomized trial(s):. • A randomized, double-blind, placebo-controlled trial in adults with post-infectious diarrhea-predominant IBS with in...

Warnings: Key safety points (with authoritative sources):. • Kidney or liver disease / severe multi-organ fail...

Studies: Randomized placebo-controlled trial (BMJ Gut) — oral glutami...

Why it works: Bromelain has anti-inflammatory and proteolytic properties that could influence allergic/inflammatory processes (and it’s been studied for sinusitis, wound healing and inflammation...

Instructions: There is no accepted clinical protocol for using bromelain specifically to treat food allergy. What follows are dosing ranges and regimens that have been used in human studies for...

Warnings: Major warnings to know before using bromelain:. • Allergic reactions / cross-reactivity: people alle...

Studies: Systematic reviews & mechanism reviews: Recent reviews s...

Why it works: FAHF-2 (Food Allergy Herbal Formula-2) is an investigational 9-herb Traditional Chinese Medicine formulation that shows promising immunomodulatory effects in animals and in vitro a...

Instructions: Phase I single-dose / short escalation study: dose escalation in early human work included up to 6.6 g (12 tablets) taken three times daily for short periods in the dose-escalation...

Warnings: Investigational status / not approved as a cure: FAHF-2 is an investigational botanical therapy stud...

Studies: Preclinical (animal) studies — strong, reproducible protecti...

Why it works: Garlic is not an established treatment for IgE-mediated food allergy. It contains compounds (allicin and other organosulfur constituents) with measurable anti-inflammatory and immu...

Instructions: Important: there is no medically accepted protocol for using garlic to treat food allergy. If someone still wants to try garlic for general immune support, these are the pragmatic...

Warnings: Garlic can be an allergen. Documented IgE-mediated reactions (including anaphylaxis in rare cases) a...

Studies: No high-quality clinical trials demonstrating that garlic tr...

Why it works: Ginger contains compounds (gingerols, shogaols, zingerone, etc.) that are anti-inflammatory, antioxidant and can reduce mast-cell/basophil mediator release and downstream cytokine...

Instructions: Forms used in studies. • Most human clinical evidence for allergic conditions uses standardized ginger extracts (ethanolic extracts with quantified 6-gingerol / 6-shogaol content),...

Warnings: Allergic reactions to ginger itself have been reported (including contact allergy and rare anaphylax...

Studies: Human clinical trialRodsarin Yamprasert et al., 2020 — “Ging...

Why it works: Curcumin (the active compound in turmeric) shows biologically plausible anti-allergic effects (mast-cell stabilisation, lower IgE/Th2 signalling, reduced allergic inflammation) and...

Instructions: Important: There is no standard, guideline-endorsed curcumin regimen for treating IgE-mediated food allergy. The information below summarizes doses and formulations used in clinica...

Warnings: Drug interactions — blood thinning and antiplatelet drugs. Curcumin/turmeric can inhibit platelet ag...

Studies: Preclinical (animal / cell) studies showing effect on food a...
