The message

from Des Higgins contains these words:

The only remotely helpful (or not) thing that I can remember about
horsetails is that some of them are fussy regarding mineral nutrients
which is why some are patchily distributed.

Another is that they take-up compounds containing gold.

In areas where there is a lot of gold which is uneconomical to extract,
horsetails are dried and burnt and gold extracted from the ash.

That's a cunning trick to make people dig it up and burn it. )

Well spotted that man :-)
