Where I live there are lots of this trees, but almost none of M. hostilis. The common extraction teks (STB, especificaly) works for the M. ophtalmocentra? And how do I harvest the roots? Do I need to let them dry on the sun (I heard that there is a specie of fungus that lives on the roots that deteriorate them if you dont let them dry on the sun)? Sorry for my bad english, it's not my primary language (brazillian portuguese is ), tell me if there is an grammatical error or mispelling, or anything that makes this thread difficult to understand... Thanks!

I saw that topic, but it doesn't answer my question as well. Endlessness said that M. hostilis and M. ophthalmocentra are very similar in appearence, but he didn't told that ophthalmocentra don't have some dangerous substances, or that the method of extraction is similar to the hostilis. Thank you anyway, I think I will have to discover it by myself
I found a post about the preparation of the trees's roots (https://wiki.dmt-nexus.me/Mimosa_hostilis), but I still have some answers about harvesting them. How much I can harvest withot killing the plant? Will I need to dig deep, or the roots grow by the sides, and not downway?

any method that works for mimosa hostilis would be fine and that there has been no association of toxicity with the species

likewise you can focus on stem bark or root bark

that thread linked to an contained all of the answers to your questions

Ok, thanks! I will try soon the rain stops falling, and I will post the results here.
