During flu season, respiratory symptoms like cough, congestion, and lingering mucus can escalate quickly, especially in kids. In functional medicine, we focus on supporting the body’s ability to clear mucus, calm airway inflammation, and recover efficiently.
Nebulizing saline is one supportive tool I keep in our home during respiratory illness. When used appropriately, it can help hydrate airways, thin mucus, and support easier breathing — without suppressing the body’s natural response.
This guide is designed to give you clear, practical guidance so you can use nebulizing safely and confidently as part of your flu-season toolkit.

Let’s get into it.
Saline: you want 0.9% saline (isotonic)
A nebulizer converts liquid saline into a fine mist that reaches deep into the lungs.
Unlike humidifiers, nebulizers deliver localized respiratory support where it’s actually needed.
Saline alone (no medication) can:
1. Wet / Productive Cough
Thick mucus or chest congestion
Saline helps loosen secretions so they’re easier to clear
Often paired with bronchodilators when prescribed
2. Dry / Irritated Cough
Airway inflammation or dryness
Nebulized saline helps rehydrate and calm tissues
Can reduce coughing fits triggered by irritation
3. Asthma or Allergy-Related Cough
Used during flare-ups under provider guidance
Helps deliver targeted airway support
Can reduce chest tightness and breathing effort
Yes — nebulizers are commonly used for infants and children with:
RSV
Asthma
Persistent coughs
Notes:
Use pediatric masks
Follow dosing and guidance from a healthcare provider
Clean equipment after every use
What I use by age:
Children: 2–2.5 mL of 0.9% saline
Adults: 3–5 mL of 0.9% saline
Timing:
1–2 times per day during respiratory symptoms
Stop if coughing worsens, wheezing occurs, or breathing seems labored
Nebulizer therapy is commonly used to support:
This approach is useful when fast, localized respiratory support is needed.
Nebulized moisture is said to:
Some integrative clinics use additional compounds selectively, based on history and tolerance:
Important Note on Glutathione
Nebulized glutathione is sometimes used to support oxidative stress and airway inflammation after viral illness or prolonged recovery.
It is not a first-line or DIY therapy and should be used only under professional supervision.
Onion Cough Syrup
Onion + honey or sugar
Let sit 24–48 hours
Refrigerate after opening
⚠️ Honey only for children 12 months+
Vitamin C
Supports immune cell function and antioxidant demand during illness.
I personally love using i01 internal Camu Camu daily for myself and my son (he’s been using it since age 4, 1 pippette)
B-Complex Vitamins
Support energy and nervous system resilience when intake is low and demand is high.
Magnesium + Fluids
Foundational for hydration, muscle relaxation, headaches, and body aches.
Possible side effects may include:
