Rewk

A tuber vine related to the sweet potato, originally native to cool, temperate deciduous forests,  particularly those with abundant maples.The vine has dark green heart-shaped leaves, small  orange-yellow flowers, and  small orange  fruit.The large root tubers, which strongly resemble those of the sweet potato, contains a stimulant in their skin. When boiled, the tea or broth from a medium to large tuber heals 2-20 concussion hits, and the tuber itself is highly nutritious.Rewk has therefore become one of the most widely cultivated herbs.
