Seasonal allergies come down to one over-eager response: the immune system over-reacts to harmless triggers like pollen, mast cells release histamine, and the familiar itchy, sneezy, congested symptoms follow. The natural approach is interesting because it works upstream of where antihistamines act. Our allergy & hayfever collection tackles the response at several points.

Upstream vs downstream — the key distinction

A standard antihistamine blocks the histamine receptor after histamine has already been released. The natural strategy works one step earlier:

• Quercetin — a flavonoid that helps stabilise mast cells so they release less histamine in the first place. High-absorption forms make a meaningful dose practical.
• Vitamin C — a natural antihistamine that's also a cofactor for DAO (diamine oxidase), the enzyme that breaks histamine down — helping empty the "histamine bucket."
• Traditional herbs — perilla and Baical skullcap (rich in luteolin and baicalein) and Albizia, traditionally used for allergic, itchy and hypersensitivity symptoms.
• Gut & immune tolerance — much of immune tolerance is shaped in the gut, so probiotics are part of the longer-term picture. See Digestion & Gut Health and Immunity.

Frequently asked questions

How is quercetin different from an antihistamine? It acts a step earlier — stabilising the mast cells that release histamine, rather than blocking the receptor afterward.
When should I start? Begin a few weeks before your trigger season rather than waiting for symptoms to peak — mast-cell support builds with consistent use.
Is allergy linked to the gut? Closely — immune tolerance is heavily influenced by the gut microbiome.
