Winter illnesses share common symptoms that can sometimes make it difficult to tell them apart. A cold is characterized by a clear runny nose and sneezing, without a fever > 38.5 °C. Acute bronchitis (90% viral) is recognized by a persistent productive cough (7–21 days). Acute sinusitis (pain on sinus pressure, unilateral purulent discharge) often occurs as a secondary infection following a prolonged cold. Sore throat (90% viral in adults) presents with pharyngeal pain upon swallowing. This distinction is essential: antibiotics are indicated only in cases of streptococcal tonsillitis confirmed by a rapid strep test—they are unnecessary and contraindicated for other viral forms.
Ginger (gingerols and shogaols) has anti-inflammatory (COX-1 and COX-2 inhibition) and natural antipyretic effects—which are beneficial for moderate fevers and winter-related muscle aches. As an infusion (2–3 g of fresh grated ginger, steeped for 10 minutes) or in capsules (250–500 mg of dry extract, 3 times a day).Eucalyptus radiata essential oil (1,8-cineole ≥ 70%) thins bronchial secretions, facilitates expectoration, and inhibits rhinoviruses. Niaouli essential oil (Melaleuca quinquenervia, cineole cut) complements these effects with its immunostimulant and antiviral action on the lower respiratory tract.
Viral sinusitis resolves spontaneously within 10–14 days with frequent nasal rinses using saline solution (Proetz technique), inhalations of eucalyptus and ravintsara essential oils, and pain relievers if pain is severe. Bacterial sinusitis—symptoms lasting > 10 days, intense unilateral pain, fever > 38.5 °C, unilateral purulent discharge—requires medical consultation and often antibiotic therapy. Propolis, whether as a nasal spray or in capsule form, can reduce the duration of viral sinusitis through its local antiseptic action on the sinus mucosa.
90% of sore throats in adults are viral in origin—antibiotics are therefore unnecessary and increase the risk of bacterial resistance. Viralsore throats can be relieved with warm saltwater gargles (3 to 4 times a day), thyme honey (which forms a protective film and has local antibacterial properties), propolis oral spray, and pain relievers if the pain is severe. The TROD sore throat test available at pharmacies distinguishes between viral sore throats (symptomatic treatment) and streptococcal bacterial sore throats (where antibiotic treatment is warranted).
Acute viral bronchitis resolves on its own within 2 to 3 weeks—antibiotics have no proven effect on its duration or severity. To speed up recovery: humidify indoor air (50–60% humidity), drink warm fluids frequently (thyme-honey herbal teas), diffuse eucalyptus radiata and ravintsara essential oils, and apply a chest balm containing essential oils by rubbing it into the skin. For the nose and associated upper respiratory tract, daily nasal rinses help prevent secondary sinus infections.
A bacterial superinfection should be suspected if symptoms worsen after an initial improvement, if a fever returns after 3 days without fever, if secretions become unilateral, purulent and very discolored, or if severe ear pain, difficulty swallowing, or shortness of breath develop. These signs require a medical consultation within 24 hours. Self-medicating with antibiotics without a diagnosis is strongly discouraged—antibiotic resistance is a major public health problem in France, where antibiotic consumption remains among the highest in Europe. In practice, the pharmacist is the first point of contact to refer patients to a doctor or to recommend appropriate symptomatic treatments.
