Roots of herbs refer to herbs whose medicinal parts are roots or mainly roots with parts of rhizomes or above-ground stumps. As far as the roots are concerned, there are no nodes, internodes and leaves, and there are no buds or very few adventitious buds. The harvesting period of root herbs is usually in autumn and winter when the above-ground part of the plant will wither, and in early spring before sprouting or when the seedlings just appear.
