Marshmallow Root for acute cough
Marshmallow root has traditional use for dry cough and throat irritation. The evidence reviewed by regulators is based mainly on long-standing use rather than strong clinical trials.
What this means
Traditional-use option for dry, irritating cough accompanied by throat irritation.
How to use it: Use only a preparation that matches established marshmallow-root directions; do not infer a medicinal dose from ordinary food or tea recipes.
Safety & cautions
Persistent cough, breathing difficulty, fever, or worsening symptoms need medical evaluation. Preparation-specific directions should be followed for medicinal use.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.
Household preparations
Practical ways to use the ingredient may not provide the same form or amount discussed in the evidence.
