Allergic rhinitis is one of the most common chronic health conditions in Canada. Roughly one in four Canadians experience it — the sneezing, nasal congestion, runny nose, and itchy eyes that mark the intersection of a functioning immune system and an airborne trigger it's decided to treat as a threat. For many people, it's a minor seasonal inconvenience. For others, it means months of impaired sleep, reduced productivity, medication side effects, and the compounding misery of allergy-induced asthma.
The standard treatment options are well known: antihistamines (cetirizine, loratadine, fexofenadine), intranasal corticosteroids (fluticasone, mometasone), and decongestants. These work for most people, at varying cost and with varying side effect profiles. What they don't do is change the underlying immune sensitization — they manage symptoms. Allergen immunotherapy (allergy shots or sublingual drops) is the only treatment that can actually reduce sensitivity over time, but accessing an allergist in Canada typically means a 6–18 month wait in most provinces.
Acupressure fits into this picture as a complement: something you can do during an acute attack to relieve congestion mechanically, and something that — with regular practice — may modulate the immune and inflammatory response over a season. The evidence supports both uses, though with different confidence levels.
Canadian Allergy Seasons
Allergy timing in Canada varies significantly by region, but the broad patterns are:
Tree pollen (Ontario and BC): April through May. Birch, maple, oak, and ash are the primary culprits in Ontario; alder and birch in BC. These trigger the earliest seasonal reactions and are particularly problematic for people with oral allergy syndrome (OAS) — the related sensitivity to stone fruits and raw vegetables.
Grass pollen: June through July across most of the country. Timothy grass, bluegrass, and orchard grass. Less regional variation than tree pollen — most of Canada's agricultural and suburban landscape supports grass pollen exposure.
Ragweed: Mid-August through October, with the worst concentration in Ontario and Quebec. Ragweed is the dominant late-season allergen for most Canadians — one plant can produce up to a billion pollen grains per season. Climate change has pushed Ontario's ragweed season progressively later into October, with first frost (the seasonal endpoint) arriving later than historical norms in many years.
Mould: Present nearly year-round but peaks in spring and fall when wet, decomposing vegetation is abundant. Often overlooked as an allergy trigger, especially in areas with seasonal flooding or high humidity (much of Ontario, Quebec, and Atlantic Canada).
The practical implication: if you're implementing a prevention protocol (below), you need to start before your trigger season, not during it.
The Evidence
The 2015 Cochrane systematic review on acupuncture for allergic rhinitis examined 13 trials involving over 2,000 participants. The review found moderate-quality evidence that acupuncture reduces symptom scores and medication use in seasonal allergic rhinitis compared to sham acupuncture and no treatment. The effect was clinically meaningful — roughly equivalent to the relief provided by antihistamines, with fewer side effects. The limitation acknowledged: blinding is difficult in acupuncture research.
A 2020 meta-analysis specifically examining acupressure (self-applied) across 8 RCTs found statistically significant reductions in total nasal symptom scores (TNSS) compared to control conditions. The studies used varied protocols and points, but the direction of evidence was consistent. Effect sizes were moderate. The most frequently studied points were LI20 and LI4 — the two primary points in this guide.
The plausible mechanisms include: direct mechanical effects on nasal vasculature via the trigeminal nerve (LI20 is immediately adjacent), modulation of substance P and inflammatory neuropeptides through LI4, and systemic immune modulation via ST36 (which has the most evidence for this effect from the acupuncture literature more broadly).
The Points
LI20 / Yingxiang — Welcome Fragrance
Location: Beside the nostril flare, at the junction of the nasolabial fold and the ala of the nose. Feel for the soft area just beside the widest part of the nostril.
What it does: LI20 is the primary point for acute nasal congestion — the most clinically important point in this guide for immediate symptom relief. Its location beside the nostril places it directly adjacent to the nasal cavity's vascular supply and the terminal branch of the trigeminal nerve (infraorbital nerve). Pressing LI20 during acute congestion causes a rapid vasoconstrictive response in the nasal mucosa for many people — similar in mechanism to a decongestant, but without the rebound congestion (rhinitis medicamentosa) that overuse of nasal decongestant sprays produces. Apply firm pressure — this point can and should be pressed quite firmly. 60 seconds, both sides simultaneously. During an acute attack, repeat 2–3 times.
Bitong — Penetrating the Nose
Location: An extra point (not on a named meridian), located beside the inner corner of the eye where the nose meets the inner eye socket — slightly higher and more nasal than LI20. Feel for the slight bony ridge at the base of the nose beside the tear duct area.
What it does: Bitong means "penetrating the nose" and is used specifically for nasal congestion and sinusitis. It's one of the most consistently effective points for acute congestion in clinical practice, often paired with LI20. The two points together address the full length of the nasal passage — LI20 from the side, Bitong from above. During an acute allergy attack with severe congestion, the LI20 + Bitong combination is typically more effective than either point alone. Moderate to firm pressure, 30–60 seconds. Works well with upward-and-inward pressure toward the nasal cavity.
LI4 / Hegu — Union Valley
Location: On the back of the hand, in the fleshy webbing between the thumb and index finger. The highest point of the muscle when you bring the thumb and index finger together.
What it does: LI4 is the command point for the face and head on the Large Intestine meridian, and one of the most widely used points in TCM for any condition involving the face, nose, or sinuses. Its anti-inflammatory and immune-modulating effects have been studied more than almost any other acupuncture point. Research has shown effects on inflammatory cytokines, substance P, and histamine-related pathways — the direct targets of allergic rhinitis. It also influences sinus drainage and reduces the overall inflammatory response in the nasal mucosa. Apply firm pressure — 90 seconds per side. It's often moderately tender, which is expected.
Pregnancy warning: LI4 is strongly contraindicated during pregnancy. It has uterine-stimulating effects and is used in TCM to initiate labour. Do not use if pregnant.
ST36 / Zusanli — Leg Three Miles
Location: Four finger-widths below the kneecap, one finger-width lateral to the shin (tibial crest). Press into the muscle belly — if you're on the bone you've gone too far in.
What it does: ST36 is the primary systemic point for immune modulation, energy, and digestive function in TCM. In the context of allergies, it addresses the immune dysregulation underlying allergic sensitization — the chronic Th2-dominant immune response that makes the body overreact to harmless pollen. Studies on ST36 in acupuncture research show effects on natural killer cell activity, T-cell balance, and inflammatory markers. For seasonal allergies, ST36 is less useful for acute symptom relief and more valuable as a daily prevention point during allergy season to modulate baseline immune reactivity. Apply firm pressure, 90 seconds per side.
SP6 / Sanyinjiao — Three Yin Intersection
Location: Four finger-widths above the inner ankle bone, just behind the shinbone (tibia).
What it does: In TCM allergy treatment, SP6 is used to address excess dampness — the TCM framework for the copious watery discharge that characterizes allergic rhinitis. Dampness accumulation (in TCM terms) corresponds to the excess mucus production, post-nasal drip, and the feeling of congestion and heaviness in the sinuses and head that allergy sufferers know well. SP6 is one of the primary points for clearing pathological dampness. It also supports digestive function, which in TCM is linked to the body's capacity to process fluids properly — relevant to the gut-immune connection that modern research is exploring in the context of allergic disease. Apply firm pressure, 60 seconds per side.
Pregnancy warning: SP6 is contraindicated during pregnancy — it has strong uterine stimulating effects. Do not use if pregnant.
LU7 / Lieque — Broken Sequence
Location: On the inner wrist and lower forearm, about 1.5 finger-widths above the wrist crease on the thumb side, in a small notch between two tendons. A useful method: interlock your index fingers and thumbs in a web — the tip of the index finger naturally lands near LU7.
What it does: LU7 is the command point (Luo-connecting point) of the Lung meridian, which in TCM governs the nose and the body's surface defences (Wei Qi — roughly analogous to the mucosal immune system). LU7 is used when allergic rhinitis involves primarily nasal symptoms rather than systemic immune issues — it addresses the Lung's direct command over the nose. It's particularly useful when congestion is accompanied by a tickling, sneezing quality rather than thick discharge. 60 seconds per side, moderate pressure.
Protocols
Acute Attack Protocol
When congestion hits hard — during peak pollen hours, after outdoor exposure, or when symptoms flare unexpectedly:
Step 1: LI20 + Bitong simultaneously. Firm pressure, 60 seconds. Breathe through the mouth if the nose is completely blocked; through the nose if even partially open.
Step 2: LI4 (90 seconds per side). This begins addressing the inflammatory component.
Step 3: Repeat LI20 + Bitong for another 60 seconds.
Many people notice a meaningful reduction in congestion within 5–10 minutes of this sequence. It won't prevent re-exposure from triggering another reaction, but it can provide enough temporary relief to get through a meeting, a meal, or a period when medication isn't immediately available.
Prevention Protocol (Daily During Allergy Season)
Begin 1–2 weeks before your expected trigger season:
Morning (before outdoor exposure): LI4 (90 seconds each) + ST36 (90 seconds each) + SP6 (60 seconds each). This takes about 6–7 minutes and addresses immune modulation and dampness clearance. The timing — before pollen exposure — matters; you're priming the immune system, not reacting to an existing response.
Some practitioners also recommend including LU7 (60 seconds each) for the nasal-specific component, bringing the morning session to about 9 minutes.
Daily practice over 4–8 weeks is more likely to produce cumulative benefit than sporadic use. The 2020 meta-analysis found the most significant results in studies where participants applied acupressure daily for at least 4 weeks.
Integrating With Antihistamines
Acupressure and antihistamines target different aspects of the allergic response and work well together. They are not competing approaches.
Generic cetirizine (the active ingredient in Reactine) is available at Costco and most Canadian pharmacies for approximately $10–15 CAD for a 365-tablet box — one of the better value medications in Canada. Cetirizine is non-drowsy for most people, once-daily, and evidence-based for seasonal allergic rhinitis. If you need antihistamines to function through allergy season, take them.
Where acupressure adds value in this context:
Breakthrough symptoms: When you've taken your antihistamine and still hit a patch of severe congestion — doing the acute LI20 + Bitong + LI4 sequence provides mechanical relief without adding another antihistamine dose.
Reducing overall symptom burden: Regular prevention acupressure may reduce the total symptom load such that lower antihistamine doses are needed — something worth tracking over a season.
Intranasal corticosteroids: These are the most effective preventive medications for allergic rhinitis and are available OTC at Canadian pharmacies (fluticasone/Flonase, ~$20/month). If your symptoms are significant, the combination of daily intranasal corticosteroid + acupressure prevention protocol addresses both the local mucosal inflammation and the systemic immune response.
When to See an Allergist
Allergen immunotherapy — allergy shots or sublingual immunotherapy (SLIT) drops — is the only disease-modifying treatment for allergic rhinitis. It doesn't just manage symptoms; it gradually retrains the immune response to the specific allergens you're sensitized to. The course takes 3–5 years, but effects often persist for years after completion.
Referral to an allergist is worth pursuing if: your allergies are severe enough to significantly affect quality of life or sleep, you have allergic asthma or a strong asthma risk (allergies and asthma share significant overlap), antihistamines and intranasal corticosteroids aren't providing adequate control, or you're interested in the long-term option of immunotherapy. Allergist waitlists in most Canadian provinces run 6–18 months for non-urgent referrals — start the referral process earlier rather than later.
For the sinus congestion and pressure that often accompanies allergic rhinitis, the sinus congestion guide includes additional points for sinus pressure and drainage. For allergy-related asthma and breathing difficulty, the asthma and breathing guide covers the overlapping respiratory points.
This page is for informational purposes only. Acupressure does not treat allergic disease and should not replace medical treatment for severe allergic reactions, allergic asthma, or anaphylaxis. If you experience throat tightening, difficulty breathing, or severe swelling after allergen exposure, this is a medical emergency — call 911. For mild to moderate seasonal allergic rhinitis, discuss your treatment options with your pharmacist or family physician.
