A simple pot to pour saline through your nasal passages

Why it may be relevant

If you would like a hands-on way to flush your nose, a neti pot delivers a gentle saline rinse to clear the mucus behind the drip.

Why try it

A neti pot is a traditional yogic irrigation device that streams warm saline through one nostril and out the other, washing out mucus and allergens.

Dose or use

Fill with lukewarm saline made from distilled, sterile, or boiled-and-cooled water; lean over a sink, tilt your head, and pour through one nostril at a time.

Time to results

Many people notice some relief soon after rinsing; use daily during flares.

Key study

Systematic review (2018, PMID 29932206): Saline irrigation for allergic rhinitis. A neti pot is one gravity-based way to deliver the saline nasal irrigation this Cochrane review found improves rhinorrhoea and nasal symptoms in randomized trials. The trials studied allergy-driven nasal discharge rather than post-nasal drip by name, so the evidence is strong support rather than proof for this specific use.

Caution

Only ever use distilled, sterile, or previously boiled water, and rinse and dry the pot fully between uses to prevent infection.

Flushes mucus and irritants straight out of your nose

Why it may be relevant

You want to clear your passages directly, and a saline rinse physically washes out the mucus and allergens feeding the drip.

Why try it

Salt-water irrigation thins mucus and rinses irritants from the nasal passages; it is a long-standing first-line home measure for post-nasal drip.

Dose or use

Rinse one or both nostrils once or twice a day using a pre-mixed saline or a sachet, made up with distilled, sterile, or previously boiled and cooled water.

Time to results

Many people feel clearer within minutes; regular use helps most over 1-2 weeks.

Key study

Systematic review (2018, PMID 29932206): Saline irrigation for allergic rhinitis. This Cochrane review of randomized trials found nasal saline irrigation improves rhinorrhoea and nasal symptoms with no important side effects. Because the trials studied allergy-driven nasal discharge rather than post-nasal drip by name, the evidence is applied here as strong support rather than proof for this specific use.

Caution

Always use distilled, sterile, or boiled-and-cooled water, never straight tap water, to avoid rare but serious infection, and clean the device after each use.

Warm steam loosens thick mucus and eases congestion

Why it may be relevant

When mucus feels thick and stubborn, warm steam helps thin it so it drains more easily.

Why try it

Inhaling warm, moist air is a simple traditional measure that loosens thick nasal and sinus mucus and soothes congested passages.

Dose or use

Breathe in steam from a bowl of hot (not boiling) water with a towel over your head for 5-10 minutes, or sit in a steamy shower, once or twice a day.

Time to results

Comfort is usually immediate and temporary; repeat as needed.

Key study

A long-standing home measure for congestion; offered on the basis of traditional use rather than a specific controlled trial.

Caution

Keep a safe distance from hot water to avoid scalds, and supervise children closely.

Herbal extract that eased allergic nasal symptoms as well as an antihistamine in trials

Why it may be relevant

When sneezing, itch and a runny, dripping nose point to allergy, butterbur targets the allergic response driving the drip.

Why try it

Standardized butterbur leaf extract blocks some of the histamine and leukotriene signals behind hay-fever symptoms; in randomized trials it eased allergic rhinitis symptoms about as well as a common antihistamine, without the drowsiness.

Dose or use

Use only a certified PA-free (pyrrolizidine-alkaloid-free) standardized extract; a typical study dose is one tablet two to three times daily. Follow the product label and choose a reputable PA-free brand.

Time to results

Many people notice easing of allergy symptoms within a few days to two weeks of consistent use during allergy season.

Key study

Randomized controlled trial (2005, PMID 16114089): Treating intermittent allergic rhinitis: a prospective, randomized, placebo and antihistamine-controlled study of Butterbur extract Ze 339. In 330 patients the standardized butterbur extract improved allergic rhinitis symptoms comparably to the antihistamine fexofenadine and better than placebo. The evidence is for allergy-driven nasal symptoms rather than post-nasal drip specifically.

Caution

Only use a certified pyrrolizidine-alkaloid-free (PA-free) product, as raw or unpurified butterbur can be toxic to the liver. Avoid if pregnant or breastfeeding, and if you are allergic to ragweed, marigold, daisy or chrysanthemum you may react to it; check with your doctor or pharmacist first, especially if you take other medicines.

Plant flavonoid that calms allergy-type nasal reactions

Why it may be relevant

When your drip flares with sneezing and itch, quercetin targets the allergic response that is driving it.

Why try it

Quercetin is a natural flavonoid thought to stabilise mast cells and blunt histamine release, which is why it is popular for hay-fever-type nasal symptoms.

Dose or use

Commonly taken as 250-500 mg once or twice daily, often alongside vitamin C; follow the product label.

Time to results

Usually taken consistently over a few weeks for allergy symptoms.

Key study

Randomized controlled trial (2022, PMID 35776034): a 4-week double-blind, placebo-controlled study in 66 adults with pollinosis found 200 mg/day of a bioavailable quercetin significantly improved allergic nasal symptoms, including nasal discharge, versus placebo. The evidence is for allergy-driven nasal symptoms rather than post-nasal drip specifically.

Caution

May interact with some antibiotics and blood thinners; check with your pharmacist if you take regular medication.

Herb used to ease hay-fever sneezing and itching

Why it may be relevant

For allergy-driven drip, freeze-dried nettle is a traditional remedy for the sneezing and itch of hay fever.

Why try it

Stinging nettle has a long history of use for allergic rhinitis, where it is reported to reduce sneezing and nasal itching.

Dose or use

Freeze-dried nettle leaf capsules are commonly taken at the first sign of allergy symptoms, per the product label.

Time to results

Often used as needed during allergy flares; some take it daily through the season.

Key study

Traditionally used for hay fever; this specific use for post-nasal drip has not been confirmed in controlled clinical trials.

Caution

May act as a mild diuretic and can interact with blood pressure or diabetes medication; check with your provider first.

Low vitamin D is linked to allergy and sinus problems

Why it may be relevant

Since your drip is allergy-related, it is worth knowing that low vitamin D is associated with allergic rhinitis and chronic sinus inflammation.

Why try it

Low vitamin D status has been linked with allergic rhinitis and chronic rhinosinusitis, common underlying drivers of post-nasal drip, so checking your level can be worthwhile.

Dose or use

Ask your provider for a blood test, and supplement only to correct a confirmed low level, at the dose they advise.

Time to results

Restoring a low level typically takes weeks to months.

Key study

Associational evidence links low vitamin D with allergic and sinus conditions; a direct effect on post-nasal drip has not been proven in controlled trials.

Caution

This is an association, not a proven cure; do not take high-dose vitamin D without testing, as too much can be harmful.

Dose or use

Commonly taken as 600 mg once or twice daily; follow the product label.

Time to results

Some notice thinner mucus within days of regular use.

Key study

Recognised as a mucolytic; its specific benefit for post-nasal drip has not been confirmed in controlled clinical trials.

Caution

Can cause nausea or stomach upset and may interact with nitrates and some blood pressure drugs; check with your provider if you have asthma.

Acupressure point used for sinus and nasal congestion

Why it may be relevant

If you would rather try a drug-free approach, GB20 is the classic acupressure point for sinus pressure and nasal congestion.

Why try it

GB20 (Fengchi), at the base of the skull, is used in acupressure to relieve sinus headaches and nasal congestion.

Dose or use
