    Althaea is Greek meaning “to cure.” More than 2000 years ago ancient Egyptians added honey to the cooked root. Ancient Romans used leaves and flowers as a strewing herb to repel lice and fleas. Emperor Charlemagne (742-814) cultivated the marshmallow in his gardens.  According to Nicholas Culpepper, 16th century English herbalist, marshmallows were a medicinal candy. The plant eased pain, helped bloody fluxes, the stone and gravel and gripping of the belly.  Considered an herb of Venus, it voided offensive humors, made milk for nursing, cured bee stings, dandruff, balding and coughs.  The French concocted the fluffy white confection in the mid 1800’s “from a decoction of marshmallow root, with gum to bind the ingredients together, beaten egg white to give lightness and to act as a drying agent, while sugar was incorporated to make the whole palatable.”  American gardens since 1700’s when John Bartram received seeds from Europe. Jefferson grew it at Monticello.
