Mythology / History / Anecdotes and traditional virtues

"Althaea" comes from a Greek word meaning "to heal". And from the Latin "bis-malva", twice as strong as mauve. Its soothing properties have been known since antiquity, and many indications were subsequently mentioned: cough, toothache, sore throat, earache, stomachache, diarrhoea, leucorrhoea, etc. Marshmallow root rattles have been used for generations to relieve painful teething in babies. Marshmallow root was used to make a soft, sweet confection called "marshmallow", which was originally made from marshmallow root.
