The protophyte of Polygonum is regarded as rhizome and root of Polygonum cuspidatum Sieb. et Zucc., perennial herbaceous, being one of the Chinese medicinal herbs most in use in ancient China.  
Cultivation: Fond of warm weather in nature, Polygonum better grows in moist & loose soil. Choose the arenaceous soil rich of humus when cultivating. It's also suitable to be cultivated by the ditch, in woodland of the hillside, and in front of or behind the house. Before soil preparation, apply tens of Kg of organic fertilizer per Mu. Plough the fields deep to 20-30cm. Prepare the earth as bed after ploughing.
Harvest:  Administration by root and rhizome, Polygonum can be digged both in spring and autumn. Root-like stem and stem, leaf are better to be gathered during spring and summer. And the root is better to be gathered in spring and autumn. Cut it to pieces while fresh after cleaning and then leave to dry in the sunshine. Those with strong root and non-withered inside are considerably as good ones. Remove the fibrous root and the tail, cut to pieces after cleaning, leave to dry in the sunshine, keep in dry places. Be cautious of mould-proof & worm-eaten. Prepared small pieces should be stored in wooden case and jar.
Distribution:  Polygonum most grows in ravine, by the river and in shady-warm places under trees, mainly distributed in the south of Changjiang River, Shan'xi, Henan and Shandong provinces in China.
