“ DISTAI ́YĬ=“they (the roots) are tough”—Tephrosia Virginiana—Catgut, Turkey Pea, Goat’s Rue, or Devil’s Shoestrings: Decoction drunk for lassitude. Women wash their hair in decoction of its roots to prevent its breaking or falling out, because these roots are very tough and hard to break; from the same idea ball-players rub the decoction on their limbs after scratching, to toughen them. ”
