Juicing Japanese Knotweed

Today we found another big patch of Japanese Knotweed (Polygonum cuspidatum, or Fallopia japonica) in our neighborhood, and we decided to try juicing it!

Here is a closer picture of the shoot coming up out of the ground. You'll notice the many joints (poly = many, gonum = knees) along the stalk.

We stripped the heart shaped leaves from the stalk, which is the part we wanted to juice. The stalk is mottled, or speckled with red, and hollow:

The stalks can be peeled, which is definitely recommended if you are eating it raw, or even preparing it by steaming. The outer part is very stringy and tough.

Since we were putting them though a juicer, though, we did not peel all the stalks. Here they are in the sink being washed:

Here is Ella juicing them:

The result was a vibrant green tart tasting juice. It would have been fine to drink on it's own, but we added some juiced apples. Though the apples we added were red (gala, I believe) the result tasted exactly like juice from Granny Smiths - very delicious!

Japanese Knotweed contains resveratrol, which is a beneficial nutrient for the heart and brain. Resveratrol is what makes drinking red wine beneficial, though there is more resveratrol in Japanese Knotweed than red wine. The resveratrol supplements are usually made using Japanese Knotweed. The concentration is highest in the roots, but is still present in the stalk.

People have also begun using Japanese Knotweed as prevention and/or treatment for Lyme's disease. For more information on this check out Stephen Herrod Buhner's book Healing Lyme, which you can find, along with other information about Japanese Knotweed and Lyme disease, at his website, Buhner Healing Lyme.

Now is the time to harvest Japanese Knotweed, if you are interested in steaming, munching on, or juicing the stalks! Best to get them as young shoots, before they become tough and woody, which will be in about a month.

Enjoy!
