History:
From Pliny:
From Culpeper:
'Gentian was first discovered by Gentius, king of Blyria. It is a plant to be found everywhere, but that of Dlyria is the finest. It has a leaf like that of the ash, but equal in size to a lettuce-leaf : the stem is tender, about the thickness of the thumb, hollow and empty, and covered with leaves at regular intervals. This stem is sometimes three cubits in length, and the root is flexible, swarthy, and inodorous. It is found in the greatest abundance in humid localities at the foot of the Alps. The root and juice are the parts of it that are used: the root is possessed of certain warming properties, but it should never be taken by women in a state of pregnancy.'
"Gentian strengthens the stomach exceedingly, helps digestion, comforts the heart and preserves it against faintings and swoonings. The powder of the dry roots opens obstructions of the liver and restores appetite. The herb, steeped in wine, and the wine drank, refreshes such as be over-weary with travelling... is an excellent remedy for such as bruises by falls. It provokes urine and the terms exceedingly, therefore let it not be given to women with child... It helps agues of all sorts, and the yellow jaundice."
