In your book “Healing Lyme” you write on page 104 that Japanese
knotweed “is a potential plant in phytoremediation work as it removes copper from copper-contaminated soil and concentrates it in its roots.” As I have been taking Japanese knotweed now for a number
of years, continue to do so and plan to continue on is it possible that I could be consuming excess copper? I buy in bulk from a reliable herb company and encapsulate. I have wondered about seaweeds and their ability to remove heavy metals and about mushrooms as they also are used in phytoremediation. Thanks immensely. I do not know what I would have done without your book “Healing Lyme.”
Unless the herb is being harvested from contaminated industrial soils its copper content should be just fine. And thanks for the kind words.
