A blocked nose is rarely serious, but it spoils your days and especially your nights. Before choosing a product, a few simple steps already help. Then three families of natural remedies share pharmacy shelves: essential oil inhalation, sea water sprays and pocket inhalers. We compared six products on composition, suitability, ease of use and price, based on the manufacturers' official pages. All products are French or Belgian brands sold in France.
Blocked nose: what to do first?
For an adult cold, the French Health Insurance recommends:
- moistening the inside of the nose with saline or a sea water spray, one nozzle per person;
- blowing your nose as often as needed, with disposable tissues;
- drinking water regularly;
- keeping your home at 18-20 °C, airing it and avoiding air conditioning, which dries the mucous membranes;
- sleeping with your head raised;
- avoiding tobacco smoke.
Note: in France, vasoconstrictor medicines (oral pseudoephedrine, vasoconstrictor nasal sprays) are prescription-only. This comparison only covers drug-free solutions.
When should you see a doctor?
See a doctor quickly with a fever above 38.5 °C, intense headaches, vomiting, difficulty breathing or swallowing, strong ear pain, conjunctivitis, signs of sinusitis (yellow discharge from one nostril, pain in the forehead, eye or cheekbone), or if symptoms worsen or do not improve within 15 to 20 days. Medical advice is also needed with a chronic illness (poorly controlled asthma, diabetes...) or for a baby.

Essential oils: precautions to know
Essential oils are concentrated.

For inhalation, use a stable inhaler and handle very hot water carefully, especially around children.

FAQs❓
The 6 most frequently asked questions from consumers:
Blow your nose gently, moisten the inside of your nose with saline or a sea water spray, drink water and keep the room aired at 18-20 °C. At night, sleeping with your head raised helps air flow. These are the French Health Insurance (Assurance Maladie) tips for an adult cold.
The most common natural options are sea water nasal sprays (isotonic for daily hygiene, hypertonic for a blocked nose) and steam inhalation with essential oils, such as Pranarōm capsules diluted in the hot water of an inhaler. Respect each product's minimum age and precautions.
The formulas in this ranking mainly use ravintsara, eucalyptus globulus and radiata, niaouli, peppermint and tea tree, inhaled or combined with sea water. Essential oils are not for everyone: children, pregnant or breastfeeding women and people with epilepsy must follow the leaflet's contraindications.
An isotonic spray has the same salt concentration as the body and is used for daily nasal hygiene. A hypertonic spray is saltier: manufacturers such as Stérimar and Physiomer intend it for a blocked nose with a cold, rhinitis or sinusitis, from age 3.
Not without caution. Pranarōm capsules are for people over 12, the Puressentiel inhaler for over 7 and the Phytosun spray for over 6; all are advised against during pregnancy and breastfeeding. For a young child, a sea water spray without essential oils is the simplest option.
The French Health Insurance advises seeing a doctor quickly with a fever above 38.5 °C, intense headaches, difficulty breathing or swallowing, strong ear pain, one-sided sinusitis signs, or if symptoms worsen or do not improve within 15 to 20 days.
