RemarksIn China, not only Pueraria thomsonii Benth. but P. pseudo-hirsuta Tang et Wang may be found in the market. Taiwanese one is the root of P. montana (Lour.) Merrill. (JP. name: Taiwankuzu). The Japanese "kuzudenpun", which is obtained from its root, is the important ingredient for making "kuzuyu" (soup of starch kudzu).
