I think my daughter was prescribed that form of chitosan by her naturopath or llmd to help get rid of toxins. I'm sorry I can't remember the details exactly. My daughter was NOT experiencing severe herxes at the time and I think it was supposed to help her stay that way. So, it's hard for us to know how much it actually did for her since there was not much difference in the way she felt. Anyway, I just wanted you to know that our docs have used it in their practice and I know they said it was to help the body deal with getting rid of toxins-----which would theoretically help lessen a herx.
Best wishes to you, bablymers mom
