Cough, headache, fever

An effective tea for a cough, headache, and fever would be:

• Marshmallow Althaea officinalis: For the cough and irritation (expectorant and demulcent); with

• Yarrow Achillea millefolium: For the fever and cough (diaphoretic and expectorant); and

• Peppermint Mentha piperita: To improve the flavor of the mixture and assist the cough (antispasmodic).
