Extracting resveratrol from Japanese knotweed root

Dear Stephen,
Can you tell me how to extract resveratrol from knotweed root? I know about grinding the root into a finer material but how do I extract the resveratrol? Please let me know.
Stephen’s response:
If you want to make a tincture (it will extract a great deal more than only resveratrol by the way) use 70% alcohol and 30% water in a 1:5 ratio. That means that if you have 10 ounces of herb (the “1”) you will need 5x that of liquid (the “5”). In other words you will need 50 ounces of liquid. 70% of that should be grain alcohol (that is, 35 ounces) the rest (15 ounces) should be water. Sounds more complicated than it is once you get the hang of it.

This protocol was incredible. After only a few weeks most of my symptoms were gone. After six months all my symptoms were gone… it has given me my life back.

    I have 2 questions:

    Is the liquid measured in weight or volume? I’m assuming the root is measured in weight.

    Do you have any advice for potentizing tinctures into homeopathic remedies?

    thank you.

    when maaaking a tincture from knotweed you say i’ll be extracting a great deal more. what does that mean good or bad

  3. DonMatheo

    I am also highly interested in resveratrol extraction from japanese knotweed.
    The extracts on the market are commonly made from the root,but what about the other parts of the plant such as leaves?
    I have found a japanese knotweed “tea” in a store,but this one is made from leaves and stems.Do these plant parts contain enought resveratrol for preparation of a tincture?
    And my second question: is a common infusion also a good way for resveratrol extraction from japanese knot weed?

    Hi Richard,
    Apologies but the Buhner Healing Lyme Q and A is now closed to new questions. All new questions being posted through the end of the year were answered by Stephen a few months ago and he is not taking anymore at this time through this website. You are welcome to try contacting him through his personal website http://gaianstudies.org but he receives hundreds of emails and cannot answer all of them. I would also try Googling to find that information or asking on herb forums on Facebook and other online venues. Best, Julie

    Well Stephen isn’t answering any more questions on this site. That’s sad , or is it? Think about all the questions he has answerd and all the people he has helped for FREE! . In this culture of profit seeking adversaries, his contribution is oustanding. He’s had to be sitting hours in front of a computer, wringing his mind to do this ! So If I were you I’d take my hat off , and send him a warm thought, just like I am doing now
    Thank you Stephen!

    I am currently trying to find out if substituting Smirnoff Blue 100 proof alcohol which is 50% with Polmos Spirytus Rektykiowany (Rectified Spirit)which is almost 200 proof – is an okay thing to do. This is my first attempt. I was told to simply add half water to the mix to make it 50% but am not sure it is that straight forward when it comes down to it. or is it?
    thank you in advance for any tips. Lesley

  10. Michelle L Garnish

    Thank you Stephen ??

    Also thank you Stephen from me. Well said Jan

    Stephen, your books and protocols saved my life and my children’s. My son with Autism has made more progress in his whole life on the protocol than with anything else. I nearly had a fatal car accident due to brain fog from Lyme, Erlichia and Bartonella and brain disease. I almost turned into an oncoming commuter train because I could not read the signal clearly thanks to severe brain fog.It missed me by inches, literally. I went on the protocol very strictly after this and am clear headed, able to work, 90 percent less symptoms and no more scary traffic accidents since then.

  13. Epiphany

    Richard, look for Buhner book on Healing Hepatitis C.

  14. Chris Glazier

    substituting? you would need to add some of the 200 proof to the 100 to bring to to the 150 proof being 75% alcohol/25% water. I’ve also read on salt to co trol it so maybe a salt additive, rocksalt or something would help.

  15. Chris Glazier

    also, sorry about the salt comment. that was for eradication lol.

    Yucca root has resveratrol too. Some research shows it may have even more than Japanese knotweed. I don’t know if it contains the imodium though.

  17. James Rose

    Hi! The leaf tea is a laxative.

  18. Kelly

    Will everclear damage the resveratrol?

  19. mark

    look more closely at the example he uses. Five to one the answer you seek is given on ounces. Weight of root x 5 in liquid oz

  20. Paul Hugh Stewart

    Well Stephen, I am a professional in this field (still learning & learning?) but I have gained quite a lot, from aspects of the process of gaining the liquid essence from Japanese Knotweed?
    All good & TO A PURPOSE.
    Thanks again for allowing me to eves-drop?
