What is Japanese Knotweed?

The first thing you see when typing in Japanese knotweed into google will be an extensive number of articles, papers, and blogs telling you how and why you should be searching out for this plant and purging it from the face of the Earth. Information on its effects can detail how it can grow in any crack or crevice in pavement, wall or road. How it can spread its roots so far as to deprive soil of any chance of fielding any other plant in its soil for the foreseeable future. How, if left unchecked, it can drain that rich soil of nutrients and moisture making the plot of land unsuitable for any future farming.

Even if the surface part of the plant, a hollow bamboo-like stem topped with a small cream coloured flower, is cut off, the roots of the plant will still allow it to bud anew during spring and early autumn. This makes the plant incredibly difficult to fully remove because if even a small part of the root is left in the Earth, it means it has every chance to expand and grow and sprout. It doesn’t help that these roots can “hibernate” and survive in soil for up to 20 years at a time.

The tenacious little plant’s rapid and damaging effects on land throughout Europe and North America have given it such a bad name that it has been labeled by the World Conservation Union as one of the world's worst invasive species.

"The plant itself is hardy, invasive, self-propagating and grows best with no maintenance or water at all, which aligns with our zero-waste ethos perfectly."

However, it's not necessarily seen in the same light in East Asia. A native to the countries of China, Korea and Japan, cultures and communities there have learned to live with and even use this plant to their benefit. In Japan the species is widely used as an edible spring vegetable and tea. In China, the species has been used as an ingredient in traditional and herbal medicines for hundreds of years and has been reputed to treat a number of ailments like swollen joints and irritated skin. More recently the use of it has been attributed to:

  • Improvement in memory and mood
  • Improvements in cognitive performance
  • Reductions in the efficacy of freed radical cells (cancer)
  • Reductions in high blood pressure and freeing clogged arteries
  • Reductions in constipation, swelling and bloating
  • Reduction of inflammation and acne

But like all things passed on through word of mouth and folk fairy tales, we have to take these claims with a grain of salt. Precious little research has been made on the effects of Japanese Knotweed on the human body.

But one thing is certain is that in the root of Japanese knotweed lies the high concentration of a unique substance: resveratrol. Resveratrol has been reported to have anti-aging and regenerative healing properties among other benefits.

Japanese Knotweed Benefits

  • Slows aging

    Resveratrol has been shown to reduce aging and promote cell growth in yeast and mice by activating a gene called SIRT1, known otherwise as the “longevity” gene. This anti-aging property makes resveratrol the perfect ingredient for an essential oil for wrinkles.
  • Improves blood flow and heart health

    Resveratrol has been shown to help reduce the “fattening”; clogging up of blood vessels and reducing high blood pressure by helping to eliminate LDL cholesterol or “bad cholesterol” in various experiments. Resveratrol essentially reduces plaque build up; clogged arteries and is the perfect ingredient to renew skincare.
  • Cancer reducing

    The high content of resveratrol in Japanese Knotweed has also been shown to help reduce the instances of cancer in mice and the instances of free radicals in cell growth in yeast.
  • Improves cognition

    On top of improving thought processes it has had limited success in protecting the brain from various neurodegenerative diseases, showing that it has the potential to protect the mind from things such as Alzheimer's disease.
  • Balances blood sugar levels

    Resveratrol has helped reduce blood sugar levels and even promote the production of insulin in some experiments.

These are but a few of the many benefits attributed to Japanese Knotweed use but in what medium would such a substance be best used in?

How to apply oils

However, as with all things it is best to find out if applying Japanese Knotweed Oil doesn’t have any unintended consequences for you. To begin with, think about applying a very small amount of Japanese Knotweed Oil onto a non-sensitive area of your skin, like a forearm or hand and see if there are any reactions to it being there.

If no reaction is felt then you may begin consistently applying a base oil and one of the oils listed above to the affected area of skin. Adjust the amount needed to be applied on the size of the affected area of skin.
