Client: A 2-year-old girl attending daycare
Initial presentation: The client presents with a 3-day history of nasal congestion, low-grade fever (38.5°C), reduced appetite and an increasing cough. Over the past 24 hours, the cough has become more persistent and wet, with mild wheezing episodes.
Parents report frequent night waking due to coughing, irritability and difficulty settling. She is still producing wet nappies.
She attends daycare 4 days/week, with multiple reports of respiratory illness among other children. Previous history includes 2-3 colds over winter months but no hospitalisations.
Diet consists of mixed family meals with relatively fruit and vegetable intake and high dairy consumption (milk 2 cups daily, yogurt and cheese). No known allergies.
Naturopathic assessment: 2-year-old-female presents with an acute viral lower respiratory tract infection consistent with RSV, characterised by bronchiole inflammation, mucus hypersecretion and mild airway obstruction. Likely cause by immature immune function, environmental exposures and dietary factors that may increase mucus viscosity.
Key factors considered:
- Immune immaturity & viral susceptibility - Young children have developing innate and adaptive immune responses, making them more susceptible to viral infections such as RSV. Reduced interferon responses can allow increased viral replication in early stages.
- Airway inflammation & mucus production - RSV infects epithelial cells of the respiratory tract, resulting in inflammation and excess mucus secretion. This narrows bronchioles, contributing to wheezing, coughing and respiratory distress.
- Microbiome & immune modulation - Early-life gut microbiota plays a crucial role in immune development. Limited fruit and vegetable intake and frequent illness may indicate reduced microbial diversity, impacting immune resilience and antiviral defence.
- Environmental exposures - Daycare attendance increases exposure to respiratory pathogens, increasing frequency and severity of infections.
- Dietary influences - High dairy intake in some children may contribute to thickened mucus, possibly exacerbating respiratory symptoms during acute infection. Low antioxidant intake may reduce antiviral resilience.
- Sleep & recovery - Sleep disruption impairs immune function and slows recovery.
Herbal medicine:
Chamomile (Matricaria recutita) - Reduces irritability, supports sleep and provides mild anti-inflammatory effects.
Echinacea (Echinacea spp.) - Enhances the immune response by stimulating macrophage activity and cytokine modulation. Clinically used to reduce severity and duration of upper respiratory infections.
Elderflower (Sambucus nigra) - Traditionally used in febrile respiratory illness. It promotes gentle diaphoresis, supports the immune response and helps relieve nasal congestion.
Elecampane (Inula helenium) - Its expectorant action assists removal of mucus from the lungs, while its anti-inflammatory activity relieves respiratory inflammation. Its antimicrobial activity works to eliminate infection.
Marshmallow (Althaea officinalis) - Soothes inflamed and irritated mucous membranes in the respiratory tract and alleviates a persistent cough.
Thyme (Thymus vulgaris) - Antimicrobial and antispasmodic actions work to relax bronchial smooth muscle, reduce coughing spasms, support clearance of mucus and target infection.

Dosage: 0.8 mL, 3 times daily (TDS) (using Fried's Rule). Dilute in a small amount of water or juice.
Additional recommendations:
Dietary modifications
- Switch to dairy-free alternatives for the duration of illness - Trial dairy-free alternatives for the duration of illness to assess impact on mucus production and viscosity.
- Increase nutrient-dense foods - Offer vegetable-rich soups, broths with miso paste, ginger and garlic and stewed apples to provide vitamin C, zinc and phytonutrients for immune support and recovery. Stewed apples are high in pectin, a soluble fibre that feeds beneficial microbes to support the gut-immune axis.
- Hydration support - Encourage frequent sips of water or warm herbal teas (e.g. chamomile). Adequate hydration helps thin mucus and prevent hydration.
Lifestyle modifications
- Humidify air in the bedroom - Use a cool-mist humidifier or sit in a steamy bathroom to help loosen mucus and ease breathing.
- Support restorative sleep - Elevate the head slightly during sleep to ease breathing and reduce coughing episodes. Encourage naps and an early bedtime as much as possible to support immune recovery.
- Nasal care - Use saline drops or spray to relieve congestion and improve breathing, especially before sleep.
Supplements
- Strain specific probiotics (Lactobacillus salivarius & Bifidobacterium breve) - To stimulate the immune system and reduce severity and frequency of respiratory infections via the gut-lung axis.
Red flags (urgent referral to GP or hospital):
- Rapid or laboured breathing worsens.
- Poor fluid intake or signs of dehydration (dry lips/mouth, nausea, fewer wet nappies, dark yellow or brown urine).
- Lethargy or decreased responsiveness.
- Develops a rash.
- Starts vomiting.
Follow up:
At the 1-week follow-up, the parents report improvement in nasal congestion and a return to normal temperature. The cough remains but is less frequent and less distressing, with improved sleep (waking once and re-settling easily). Appetite has returned and fluid intake has improved. There was no observed difference in mucus viscosity after removing dairy.
Wheezing has reduced, with no further signs of respiratory distress. The client is more active and less irritable. Advised parents to continue the herbal formula until the bottle is finished and to re-introduce moderate amounts of dairy back into their daughter's diet.
The long-term focus includes immune resilience: improving dietary diversity, supporting gut health and reducing the frequency of recurring respiratory infections during the colder seasons.
