White Chrysanthemum (Ju Hua) I

I need to find the seeds for Chinese White chrysanthemum called Ju Hua, and I don't know what the other names for it may be. It is a medicinal herb, and relatively bitter. It stabilizes blood sugar. It is sold in Chinese herbal shops. I would appreciate any information you could send on this. I have the medical paper on this, although it is in Kanji.

"Ju hua" is Chrysanthemum morifolium. This is the ordinary pot mum.
