The world’s most hated weed might be the fountain of youth! Japanese knotweed contains extremely high concentrations of resveratrol, the plant-chemical a Harvard researcher calls the “Holy Grail of anti-aging research,” used to treat heart disease, cancer, diabetes and Alzheimer’s.
Sometimes referred to as “Godzilla weed,” Japanese knotweed is one of the most invasive and hated plants on Earth.
It grows through freeways and building foundations, destroys property values, and is even illegal to plant, transport or dispose of improperly in many countries.
It’s also one of the most medicinal plants on the planet, containing more of the polyphenol resveratrol than any plant we know of.
Harvard researcher Dr. David Sinclair has called resveratrol “the Holy Grail of anti-aging research” after witnessing the anti-aging effects the chemical had on mice in his lab.
Used in Chinese and Japanese medicine for over 2000 years, Japanese knotweed is used today to treat cardiovascular problems, cancer, diabetes and Alzheimer’s.
In addition to being a rich source of minerals and vitamins, it’s prized component resveratrol has been the subject of hundreds of medical studies in recent years.
Resveratrol is a powerful antioxidant that thins the blood and clears blockages in the arteries, helps with oxidation of fats and fat metabolism, and has anti-bacterial, anti-viral and anti-fungal properties.
Japanese knotweed is also one of the only effective remedies for Lyme disease, pulling the bacteria out of the nervous system.
Herbalist Yarrow Willard shows us how to identify Japanese knotweed and how to make a resveratrol tincture from its roots in the video below:
Knotweed is a highly prized mountain vegetable in Japan and China, Willard says.
He recommends pickling the shoots with magnesium salt to get rid of oxalic acid before eating.
He’s nicknamed the resveratrol in its roots “reverse-it-all,” as its known for reversing so many ailments and signs of aging.
It’s not coincidence that invasive weeds grow wherever humans have disturbed the soil, Willard says, noting that knotweed doesn’t grow in the forest.
“We need plants like this in our lives,” he says. “They keep popping up everywhere, and we keep trying to get rid of them with the aggressive agro destroyer mentality.”
