Hayfever affects around one in four adults in the UK, with symptoms typically beginning as tree pollens rise in early spring and continuing through grass pollen season into summer. The conventional explanation – immune overreaction to airborne allergens – is well established. But TCM offers an additional layer of understanding: one that may help explain why some people suffer badly and others not at all, and why natural approaches taken before the season begins can make a meaningful difference.
The TCM View of Allergic Reactions
In Traditional Chinese Medicine, hayfever and seasonal allergies are understood as a combination of external and internal factors. Externally, the rising Wind energy of spring carries pollen and triggers the body's response. Internally, two organ systems are most often implicated: the Lung (which governs the surface of the body, the skin, and the mucous membranes – the body's first line of defence) and the Liver (whose overactivity in spring can generate heat that rises to the head, worsening symptoms).
People who tend to suffer from hayfever often have what TCM calls Wei Qi deficiency – a weakening of the body's defensive Qi that makes the surface of the body less able to regulate its response to external pathogens like pollen. Interestingly, many of these people also tend to feel the cold easily, be prone to catching colds, and experience fatigue – all signs of a Lung Qi pattern that TCM practitioners would address as part of allergy treatment.
The Liver connection is more specific to spring: when Liver Qi is stagnant or the Liver is overheated, the rising yang energy of spring can cause symptoms to manifest in the head – red, itchy eyes (the Liver opens to the eyes), congestion, headaches, and skin reactions. This is why TCM practitioners often treat hayfever partly through the Liver as well as the Lung.
Building Resilience Before the Season
One of the most consistent pieces of advice from both TCM and natural medicine approaches is to begin supporting the body before pollen season arrives. Many of the most effective natural approaches take weeks to build up, and beginning in late winter or very early spring – before the first tree pollens appear – may result in a noticeably less reactive season.
Nettle (Urtica dioica) is one of the best-evidenced natural approaches for hayfever. It contains compounds including quercetin that may help stabilise the mast cells responsible for releasing histamine. Regular nettle tea or freeze-dried nettle capsules taken from late winter onwards is a traditional approach that many people find reduces the severity of their seasonal symptoms. Fresh young nettles, foraged in early spring, are the most potent form – but both tea and capsules are effective and widely available.
Quercetin itself – found in onions, capers, apples, and particularly in red onion skin – is a natural anti-histamine compound. Including quercetin-rich foods regularly through late winter and spring may help modulate the immune response to pollen. Some people also supplement quercetin directly during allergy season.
Dietary Approaches
There is reasonable evidence that a high-histamine diet can worsen hayfever symptoms in sensitive individuals, because the body is already managing a histamine load from the allergic response. During the peak season, some people find it helpful to reduce fermented foods (including alcohol, aged cheese, vinegar, and fermented vegetables), which are high in histamine or which encourage histamine release. This isn't a permanent change – fermented foods have significant health benefits – but a temporary moderation during the worst weeks may help.
Conversely, foods that are naturally anti-inflammatory may help reduce the severity of the immune response. This means the general spring dietary shift recommended in TCM – more fresh greens, lighter foods, less meat and dairy – is supportive from an allergy perspective too. Omega-3 fatty acids (from oily fish, flaxseed, and walnuts) have anti-inflammatory properties that may help dampen allergic reactivity over time.
In TCM, dairy and rich, mucus-generating foods (what the tradition calls Damp-producing foods) are thought to increase the production of phlegm and worsen respiratory allergies. Many people who suffer from hayfever find that reducing dairy during the season reduces congestion and catarrh – a common clinical observation across both TCM and naturopathic approaches.
Herbal and Natural Remedies
Beyond nettle, several other herbs have traditional use and some supporting evidence for seasonal allergies:
- Elderflower (Sambucus nigra) – a traditional European remedy for hay fever. Elderflower tea or elderflower tincture is used to reduce mucous membrane reactivity, ease congestion, and soothe inflamed sinuses. Dried elderflowers make a pleasant daily tea through spring.
- Eyebright (Euphrasia officinalis) – traditionally used specifically for allergic eye symptoms – redness, itching, and watering. Available as a tea, tincture, or eyedrop preparation. Often combined with elderflower in herbal allergy formulas.
- Plantain leaf (Plantago lanceolata) – ribwort plantain is a common hedgerow plant with documented mucilaginous and anti-inflammatory properties. It is traditionally used to soothe irritated mucous membranes in the nose and throat.
- Chrysanthemum flowers (Ju Hua) in TCM – cooling and specifically directed at the Liver and eyes, chrysanthemum tea may help reduce the red, itchy, watery eye symptoms that many hayfever sufferers find most distressing. Simple to make as a daily tea from dried flowers, available in Chinese supermarkets.
- Bi Yan Pian – a classical TCM formula commonly used for nasal allergies and congestion. It combines herbs that clear Wind, reduce inflammation, and open the nasal passages. Available from specialist TCM dispensaries and some health food stores.
Practical Lifestyle Measures
Simple practical measures can make a significant difference during peak pollen season. Pollen counts are typically highest in the early morning and early evening – adjusting outdoor activity to midday when counts are lower, and keeping windows closed in the morning, can reduce exposure meaningfully. Showering and washing hair after being outdoors removes pollen from the body before it has time to accumulate.
Nasal rinsing – using a neti pot or saline nasal rinse – is used across many traditions as a way to physically clear pollen from the nasal passages. There is reasonable evidence that regular nasal irrigation reduces symptom severity and frequency in seasonal allergy sufferers. It may take some getting used to but is very well tolerated once the habit is established.
Local raw honey – specifically honey made by bees foraging in your own region – is a popular folk remedy based on the idea of gradual desensitisation to local pollens. The evidence is modest, but many people include a spoonful of local raw honey in their daily routine from late winter onwards as a gentle, pleasant practice with no downside.
When to Seek Further Support
If hayfever significantly affects sleep, concentration, or quality of life, it's worth discussing with a GP. Antihistamines and nasal steroid sprays are effective first-line treatments. Allergen immunotherapy (desensitisation) is available via referral for those with severe, persistent symptoms. A TCM practitioner may also be able to address the underlying pattern – particularly if there is a constitutional tendency towards immune reactivity, repeated colds, or respiratory sensitivity – rather than managing symptoms season by season.
