Do you happen to have any sources to back up the conclusion that this will definitively eliminate any health risks? I just can't feel comfortable getting near anything that's been touched by mold, nor recommending to anyone else that it's safe for them to it breathe into their lungs no matter what possible treatment might be considered.
My own fear is two-fold, given I have mold allergy to worry about in addition to the usual health concerns. So I lean toward "nuke it from orbit" when it comes to considering how to deal with any given mold incident...
Obviously if you have a mold allergy, you should not be exposed to any relevant mold allergens. That is, you shouldn't go near anything you know to have mold (of the type you've been diagnosed as allergic to).
But as I noted, essentially sterilizing this herbal material, heating/baking it much as you might food (up to low 200˚F for ≥20 minutes) will get rid of all living organism potential hazards (including bacteria, fungi/mold, insects, protozoa, spores, viruses, pollen, spiders; and deactivate most or all natural toxins too). I can't provide references for this -- It's just basic to civilization. The main reason we heat food before eating (or canning/preserving) it is to sterilize it (kill everything) and deactivate any residual biologically active proteins (enzymes, toxins). Treating "moldy" herb much as one would other vegetables, fruit, herbs, etc. should be good enough (for those not actually allergic). I don't see the problem or solution being much different from say cutting off a surface molded part of a piece of bread, fruit, cheese, vegetable, etc., then baking the remainder (the clean-up and bake regimen I suggested), then consuming it.
