Invasive Plant Medicine: Japanese Knotweed

Invasive Plant Medicine: Japanese Knotweed


Hi, I’m Timothy Scott the author of Invasive Plant Medicine and I’m here to talk about my favorite plant here – Japanese Knotweed This is really my favorite plant and it’s the plant that instigated this whole journey into
writing a book and I got to know Japanese Knotweed many years ago when I first started treating lyme disease and learned from Stephen Buhner that that this was the most important herb to use in the treatment of lyme disease Since then I’ve learned many things about the plant – not only how it’s helping humans heal from disease but also how it helps rehabilitate lands where it lives and helps clean the environment
for us and helps protect these areas that have been disturbed by human development and pollution So it’s a very important plant and there’s a
good reason why it grows here and flourishes where it does It’s a warrior plant and it has no fear of shovel or poison or extreme environments – you can see it growing in basically any environment throughout the United States and various soil compositions, different elevations Polygonum cuspidatum is the Latin name for it Studies in England have found that the plant is primarily a female plant and the Japanese Knotweed Alliance has called Japanese Knotweed the largest female in biomass terms and with this it does not spread so much by seeds – it spreads more by roots and fragments of roots and that’s what we see here mostly in America These plants spread mostly by root fragments Any little piece of the root that is broken free from the plant can set up whole colonies by themselves What most likely happened here is that down the river a ways just a little bit broke off and over time they’ve been able – The roots have spread throughout the land and into this area and have created huge stands of this plant And if you take a look over here you can also see that some folks have tried to really… tried to get rid of this plant And in fact this is the second cutting they’ve done this year and it’s still coming back in – and really, the cuttings don’t do much to keep it in check – it just cuts them back and it still flourishes here The root is where we find the medicine I learned about six years ago from Stephen Buhner – when he was writing the book “Healing Lyme” that Japanese Knotweed was the most important herb
in treating lyme disease and since that time I – in my herbal practice it has been the
mainstay herb that I’ve been using and with really great success with folks Now the plant has been used for thousands of years in far east medicine and is only now being sought after in the west for herbal medicine – and mainly with the work that Buhner has done with lyme disease The roundabout way we’ve learned more and more about
Knotweed is through the compounds that are found within the root The most notable compound in Japanese Knotweed root is resveratrol – resveratrol is an antioxidant that gained notoriety with the “French paradox” – the study that found resveratrol to be
the active component in preventing heart disease and other degenerative diseases and that was through looking at the diet of Europeans who ate a rich, fatty diet, with the all-important red wine And in that red wine was found resveratrol and so that was the component that they found that was helping prevent heart disease and other degenerative diseases Not only does Knotweed have resveratrol, but it has many other compounds in it that address various aspects of the body and healing The most important piece of Knotweed for medicine is the root and what I have done is harvest the root and cut it into pieces and dry it and then further powder that and put it into capsules That has been the easiest way for me to provide that for folks Some people do make tinctures out of it – though Buhner does not recommend that in the treatment of lyme disease – so I haven’t pursued that much And you can always use it in it’s raw form and make teas and
decoctions out of it by taking some of the roots, you know… a few ounces at a time and adding that to a pot of water and boiling for a good twenty or thirty minutes to extract these compounds from it Another great potential for Japanese Knotweed is it being a potential source for biomass for electricity and energy needs and as you can see here grows prolifically and often grows right along roadsides so it’s easy to harvest It grows inches a day and the potential of harvesting a few times a year is there With simple alterations in equipment that’s available already

these plants could be harvested and made use of for our energy needs – and that is another potential for communities with this plant

  1. I discovered my property had this plant growing and once I found out it grows very tall and thick and most importantly fast I've been transplanting the young as a privacy screen between neighbours. I was watching videos about how people want to get rid of it but in northern climates it grows where other things might not. I transplanted into a lawn that two inches down is almost pure sand and it's growing great. So for any northerners I highly suggest it. Bonus that it has health benefits!

  2. Thank you for making this video! I am grateful that there are others out there who see these "invasives" as friends. Blessings! -Sunny

  3. Today I was chopping down Japanese Knotwood. It's bad for the soil and prevents other plants from growing. Though it is edible animals here wont eat it because they dont know what it is. This plant has no enemies here in the U.S. so there is nothing to stop it from growing.

  4. In the UK, it is an offence under section 14(2) of the Wildlife and Countryside act 1981 to "plant or otherwise cause to grow in the wild" any plant listed in Schedule nine, Part II to the Act, which includes Japanese knotweed. Over £150m is spent annually on Japanese knotweed control, and a decision was taken on 9 March 2010 in the UK to release into the wild a Japanese psyllid insect, Aphalara itadori.[16] Its diet is highly specific to Japanese knotweed and shows good potential for control

  5. Wow and to think we kill these plants off in the UK. We have two gardens one does not have this plant and the other down the far bottom does. My little girl and I like this plant as it flowers and is really very woodland like which adds that bit of fairy magic to children's dreams. I want to thank you for this amazing video and the amount of information you have given. We will keep our Japanese Knotweed and if any one wants the roots get in contact. Healing is good!

  6. Yeah we love those easy growers I planted another invasive between my "neighbor" and I (against her advice!) a Mimosa, beautiful for a few years then the roots literally broke the corner off her driveway (6 inch thick cement)! Then it was unkillable! Took a couple years to stop it, it's a wonder she is even talking to me… lol I learned the hard way… love those wild thangs… but, duh!

  7. In truth most of the complaints are that it is growing in "good" soil but the ridiculous thing is the way that some go about removing it, the whole "nuke them all" attitude is as bad as the invasiveness… I had come to marvel at its strength and then wondered why God had instilled in them such vigor. Glad to hear that others are on the track of seeing their worth and even helping reduce their spread by using them sustainably. Make a fermented compost to control the waste trimmings.

  8. You can't be serious!

    This is one of the most insidious plants we battle! I can't believe you're suggesting that people allow it to grow.

    This is one of the most invasive plants, overtaking native vegetation, and gobbling up great amounts of time and money to control it.

    Stop it!!!!

  9. Bob you are mistaken… The plant is highly medicinal… and it can be harvested… instead of putting poison into the earth. Resveratrol is a highly valued medicine, made commercially and sold expensively. If enough pepole harvested it it wouldn't be invasive. Nature tells us something and in our determination to destroy it we don't listen. Stop now and listen again to the video please

  10. Plant is ubiquitous around here. Normally I'm ok with letting things be, but this plant will take over, and choke everything else out. I highly recomend against willfully plating it, because it takes years to get rid of.

  11. It grows where ticks live, the Maker knew we would need it 🙂 . That reminds me of someone I heard, can't remember who, was saying that eating tomatoes protects our skin from the sun, so God has them grow easily during the summer, but never the winter because we don't 'need' them then 🙂

  12. In South Korea, Kudzu root is prized for menopausal men and women and balancing hormones. Happy drinking.

  13. this stuff is easy to kill, you put old carpet on top of it, then mix roundup with diesel fuel and a bit of dawn dish soap, put the carpet down and spray it with the stuff.

  14. But in fact it isn't resveratrol that prevents the French from having heart attacks and strokes, it is the large amount of butter and other saturated fats they consume. Same as the Japanese. (Prof Toxachito Hamayaki)

  15. Isn't it interesting how many 'weeds' have almost super healing powers? I know it's invasive and can cause problems for properties as it is such a pain to control, but as they say 'every cloud has a silver lining'! Thanks for the info.
