I'm using a mushroom mix designed to increase immune function too, but it's a different brand. I would encourage you to exercise caution in starting and increasing doses, as it can make a person herx pretty strongly due to the increase in immune function. This means that it's going after everything all at once.
I'm not sure on the interactions, but do believe it's safe with the abx and the herbs - but it's always best to check with the practitioner that prescribed it, or another source that is familiar with what you are taking.
