Hot Fluids and Chicken Broth

Reviewed by the Nimbera editorial team · Last updated May 2026

A controlled study (PubMed 359266) measured nasal mucus velocity and found hot chicken soup increased clearance to 9.2 mm/min vs 6.9 mm/min at baseline, outperforming hot water alone. A 2000 in vitro study found chicken soup inhibited neutrophil chemotaxis.$2-$6 per carton of store-bought broth; minimal cost if homemade

How to use

Drink 8-12 oz of hot chicken broth, chicken soup, or hot herbal tea every 2-3 hours while awake during acute illness. Sipping by mouth - rather than drinking quickly - maximizes exposure at the back of the nose and throat where the benefit is observed. Maintain overall fluid intake of 8-10 glasses of total fluids per day. Warm lemon water with honey is an acceptable alternative for symptom relief.

How it works

Hot liquids work through two mechanisms: the steam and heat improve nasal airflow by thinning mucus secretions and accelerating mucociliary clearance; and chicken broth specifically provides cysteine (an amino acid released from chicken protein during cooking) that may have mild anti-inflammatory effects. Adequate hydration thins mucus and supports immune function.

Where to buy

Homemade or store-bought low-sodium chicken broth at any grocery store.

Typical cost: $2-$6 per carton of store-bought broth; minimal cost if homemade

Safety notes

No significant drug interactions. High-sodium broths may be problematic for those on sodium-restricted diets or taking lithium (sodium affects lithium renal clearance). Very hot liquids can irritate or burn mucous membranes - allow to cool slightly before drinking. Not a substitute for antiviral medications in high-risk individuals.

Drug & supplement interactions

  • Always tell your doctor or pharmacist about any supplements you take.
  • Interactions can occur with prescription medications, blood thinners, and immunosuppressants.
  • Herbal remedies can affect how the body absorbs or metabolises drugs.
  • Check drugs.com interactions checker before starting.
