Mandrake, or Mandragora, is a tuborous plant. Meaning the most useful part of it is a root that absorbs water. For the more simple minded people, it grows like a carrot, or potatoe. The Mandrakes are most effective for atidotes when they are in adulthood, feamales are good for Love potions when they are in their adolescent stage, and baby mandrakes are best when associated with pregnancies. When a mandrake screams, it has the potential to kill people who hear it. Be sure to cover your ears with somthing effective before uprooting. A woman mandrake has a curvature root shape, and the males have a braoder, stiffer root shape.
Basically, Mandrakes are an important part of the wizarding society.
