Polygonum chinense/ Chinese Knotweed

simsalabimMarch 14, 2012

I have Polygonum chinense/ Chinese Knotweed growing nicely in my garden but have not much of an idea what I should use it for. It tastes horrible and must therefore have only medicinal use.

Here is a short description and a picture of this plant:

Were you eating the leaves? It's the root that's used.

Thanks! No I didn't eat the leaves, just nibbeled to see how it tastes, they look pretty and palatble but taste yucky.
What are you using the root for? (I guess I won't rip them out for harvesting the root anyway because it is a pretty plant, justin case you never know)

It's considered an energy restoration root. It strengthens the Liver and Kidney meridians with neutral and drying energies. It raises the vital forces by tonifying the Qi, Blood and Essence.

Must use caution, though. If you have other outstanding health conditions, using knotweed root can and probably will dam up the energies and cause side effects. Not harmful side effects, but uncomfortable ones.

I found that Polygonum chinense is synonym of Fagopyrum dibotrys.
By pfaf.org edible parts are leaves and seeds.
Medical usage:
Anodyne; Anthelmintic; Antiinflammatory; Antiphlogistic; Antispasmodic; Cancer; Carminative; Depurative; Febrifuge; Hypotensive.

Please, recheck your information. The polygonum being discussed is polygonum multiflorum. The one you're talking about is perennial buckwheat. Totally different herbs.

Sorry, but at begining was writen "polygonum chinense" which is fagopyrum dibotrys (perenial buckwheat), polygonum multiflorum is synonym of Fallopia multiflora which is a perenial climber.

Yes. At the time, I didn't know why I chose Latin class in high school (1960's). But when I got into herbology, the latinus termus' came in handy. Even now, occasionally, I have to double check an herb's name by the latin name or, sometimes, by its botanical name for accuracy.

If these leave are a potherb then you must have a special recipe. I would describe the taste as yuck.
When do you dig out the root? (If I ever will do that because the plant is very pretty IMO)

If your question is directed at me, then I don't know. lol I'm an herbalist, not a botanist, though I do some wildcrafting for the fun of it. Many perennials in the wild are harvested in the spring before the juices flow up from the roots into the herb above ground.

You can probably more easily buy this root. I buy it under the name Ho Shou Wu in Chinese.

I believe it to be Japanese Knotweed not chinese.

Dilute at the rate of 1 part herbicide to 40 parts of water for treatment of most prenial weeds and 1 to 40 for treatment of hardy invasive plants like Japanese Knotweed and 1:20 for Ivy
