    Greek physician Dioscorides named Polygonatum in the 1st century, which means “many jointed” referring to scars on the rhizome.  Medieval herbalists opined that Biblical figure Solomon put scars on the rhizome to demonstrate the plant’s curative powers.  P. multiflorum cultivated in English gardens by 1450.  In 1596 English herbalist Gerard (1545-1612) endorsed its use to repair broken bones – mix the pulverized root and drink it with ale to “gleweth together the bones in very short space.”  He also claimed fresh stamped root would cure cuts and bruises for “women’s willfulness in stumbling on their hasty husband’s fists.” According to Culpepper, Italian wives “much used” this remedy.
