In short:

  1. A natural nasal spray for a blocked nose relies on a hypertonic saline solution, saltier than standard saline (9 g/L): Physiomer goes up to 22 g/L of mineral salts. The difference in concentration draws water out of the nasal lining and frees the airflow.
  2. Pranarôm, Puressentiel and Phytosun Arôms add essential oils to this base. Pranarôm combines six of them with organic propolis at 0.3%, from age 3, for 8.90 euros per 15 ml.
  3. Puressentiel is the most affordable aromatic spray (6.39 euros per 15 ml), with a clear leaflet on its conditions of use. Phytosun Arôms is indicated from age 6.
  4. Physiomer (5.98 euros per 125 ml, from age 2) and Stérimar (7.29 euros per 100 ml, from age 3) are the plain seawater options, the cheapest and the only ones suitable for toddlers.

Three families of sprays behind one promise

The blocked nose shelf mixes three kinds of products that do not work the same way. The first is plain hypertonic seawater, such as Physiomer. The second adds marine trace elements to that seawater, which is the case of Stérimar with copper and manganese.

The third combines the saline base with essential oils and plant extracts: Pranarôm, Puressentiel and Phytosun Arôms. It is the family with the most actives, and also the one that calls for the most attention regarding age and pregnancy.

Vasoconstrictor sprays, sold as medicines, belong to another category and require pharmacy advice. They fall outside this comparison, which focuses on formulas of natural origin.

How a hypertonic solution clears the nose

A blocked nose is caused less by mucus than by swelling of the nasal lining. When it becomes inflamed, during a cold or rhinitis, its tissues fill with water and narrow the airway.

A solution saltier than the body’s internal environment creates an osmotic pull. In contact with the lining, it draws out part of the fluid, which can reduce swelling and thin the mucus. This is the principle shared by the five sprays in the table.

Standard saline, on the other hand, is isotonic: 9 g of sodium chloride per litre, the concentration of blood. It rinses the nasal passages without this osmotic pull, which makes it a hygiene product rather than a decongestant.

“Hypertonic saline nasal irrigation brings greater benefits than isotonic saline in symptom reduction, with larger effects in rhinitis and in patients under 18.” Kanjanawasee et al., meta-analysis of 9 studies involving 740 patients, American Journal of Rhinology & Allergy, 2018

The same meta-analysis found no difference on the overall sinonasal quality of life score. The benefit of hypertonic saline therefore concerns perceived discomfort, without making it a cure-all.

Pranarôm: an organic nasal spray combining salt, propolis and six essential oils

Pranarôm is a Belgian aromatherapy laboratory founded in 1991, specialising in chemotyped essential oils, meaning oils defined by their biochemical composition. Its breathing and ENT range includes around fifty products, among them a decongestant nasal spray registered as a medical device.

A composition detailed on the leaflet

The formula starts with a hypertonic saline solution, textured with xanthan gum. It adds witch hazel extract, organic propolis at 0.3% and a blend of six organic essential oils dosed at 0.1%.

The six oils are eucalyptus radiata, cineole myrtle, saro (Cinnamosma fragrans), black spruce, rock rose and rose geranium. The first three share a high content of 1,8-cineole, the molecule associated with the feeling of clearer airways.

The laboratory highlights a reduction in mucus viscosity within 30 seconds, measured in an in vitro test.

What sets it apart from other aromatic sprays

  • The number of essential oils. Six organic oils.
  • The age of use. From age 3, with graduated dosage: 1 to 4 sprays per nostril for over-12s, 1 to 2 from 6 to 12, a single one from 3 to 6, 5 times a day at most.
  • Shelf life once opened. 30 days, which limits waste over a cold lasting a few days.
  • Certification. Organic ingredients certified by Certisys.

Pranarôm offers an active-rich formula in a 15 ml bottle, at 8.90 euros.

Puressentiel, Phytosun Arôms, Physiomer and Stérimar: four other approaches

The other four brands do not rely on the same levers. Looking at them one by one explains the gap in price and use.

Puressentiel, the most affordable aromatic spray

The Puressentiel respiratory spray combines hypertonic seawater, organic rosemary floral water and four organic essential oils: ravintsara, rose geranium, eucalyptus radiata and niaouli. It also contains propolis and echinacea extract. The adult dosage is 2 sprays per nostril, 5 times a day at most, and a single one for children over 3.

At 6.39 euros per 15 ml, it is the most affordable of the essential oil sprays. Its leaflet specifies the conditions of use: to be used within two weeks of opening, with the advice of a healthcare professional during pregnancy or breastfeeding.

Phytosun Arôms, the fresh sensation

Phytosun Arôms relies on hypertonic seawater, eucalyptus and niaouli essential oils, and a wild mint extract. The latter brings an immediate feeling of freshness with each spray.

The 20 ml bottle costs 7.29 euros, or 3.65 euros per 10 ml. The spray is intended for adults and children over 6, at one spray per nostril up to 6 times a day.

Physiomer, seawater with nothing added

Physiomer uses seawater collected along the Saint-Malo coast, undiluted, at 22 g of mineral salts per litre, with no preservative and no propellant gas. The spray is indicated from age 2, the lowest age in the comparison.

At 5.98 euros per 125 ml, it is by far the cheapest per millilitre. It offers pure seawater with no added active, suited to family use from age 2.

Stérimar, enriched seawater

The Stérimar hypertonic spray contains 75% seawater, supplemented with copper and manganese salts. It is intended for adults and children over 3.

The brand works in courses: 2 to 4 sprays a day in each nostril, over 10 to 15 days. The 100 ml bottle costs 7.29 euros.

Which nasal spray to choose for your situation

The right spray depends less on an absolute ranking than on the person’s profile and timing.

The gesture that makes the difference

A spray is used after blowing the nose, otherwise the solution dilutes in the mucus before reaching the lining. Pranarôm recommends shaking the bottle, inserting the tip into the nostril and spraying while breathing in gently through the nose.

The tip is cleaned with hot water after each use, then left to air dry. One bottle per person remains the rule, so the cold is not shared with the rest of the family.

Combining the spray with other aromatic gestures

The spray is not the only option. An essential oil inhalation over a bowl of hot water takes over in the evening, when congestion gets in the way of falling asleep. The guide to essential oils to unblock the nose details the oils most used through the olfactory route.

For a cold that is just starting, the article on essential oils for the common cold presents the classic blends, and the guide on how to use eucalyptus radiata essential oil explains its routes of use for adults and children.

Precautions to keep in mind

Essential oils are not sprayed in children under 3 without the advice of a doctor or pharmacist. A known allergy to propolis, echinacea or one of the oils in the formula also rules out the spray concerned.

A blocked nose lasting more than ten days or so, or accompanied by fever or facial pain, calls for medical advice.

Frequently asked questions

What is the best natural nasal spray for a blocked nose?

Five sprays are available on the French market. Pranarôm combines a hypertonic saline solution, organic propolis (0.3%) and six organic essential oils, from age 3, for 8.90 euros per 15 ml. Puressentiel relies on hypertonic seawater, four organic essential oils, propolis and echinacea, at 6.39 euros per 15 ml. Phytosun Arôms blends seawater, eucalyptus, niaouli and wild mint, for adults and children from age 6, at 7.29 euros per 20 ml. Physiomer (5.98 euros per 125 ml, from age 2) and Stérimar (7.29 euros per 100 ml, from age 3) stick to plain or mineral-enriched seawater. Pranarôm offers an active-rich formula (six essential oils and propolis), while plain seawater remains the cheapest option.

Seawater spray or saline solution: what is the difference for a blocked nose?

Standard saline is isotonic, at 9 g of salt per litre, the same concentration as blood. It cleans the nasal passages without decongesting them. A hypertonic spray is saltier, around 22 g of mineral salts per litre for Physiomer: through osmosis it draws water out of the swollen lining, which frees the airflow. For a blocked nose, hypertonic is the form most often chosen, while isotonic is used for daily nasal hygiene.

Is an essential oil nasal spray suitable for children?

It depends on the formula. The Pranarôm and Puressentiel sprays are indicated from age 3, with a single spray per nostril for the youngest. The Phytosun Arôms spray is intended for adults and children over 6. Under 3, only seawater is an option, Physiomer being indicated from age 2. Asking a pharmacist remains useful for a toddler.

Can a natural nasal spray be used during pregnancy?

Aromatic sprays call for particular caution during pregnancy and breastfeeding, as essential oils do at this time. A plain seawater spray is the option usually chosen. For any aromatic formula, ask a doctor, midwife or pharmacist before the first use.

How long can a natural nasal spray be used?

Stérimar recommends a 10 to 15 day course. Essential oil sprays are limited to 5 uses a day for Pranarôm and Puressentiel, 6 for Phytosun Arôms. Once opened, the Pranarôm bottle keeps for 30 days, the Puressentiel one for two weeks. Congestion lasting more than ten days or so deserves a doctor’s opinion.
