Aiduotuo has green leaves, green stems, and black roots. It grows in sunny, south-facing places and beside streams. It does not wither in winter nor become lush again in spring. When fresh, there is white sap inside the stems; the texture is fine, shaped like a chrysanthemum flower; it bears black seeds. After many years, melon-like structures form on the roots. Yellow flowers are toxic and must not be used medicinally. White flowers are the best, followed by purple flowers; they treat many diseases.
