So, when last we left Canoga Falls, Daryl had stopped by the local co-op grocery and picked up all kinds of herbal powders and such for soap making. This weekend I want to use goldenseal and wheatgrass in a batch of cps. The problem is I have no idea how to infuse them. Anybody have and experience with this sort of thing? Both are very fine powders. Do you mix them in oil like oxides? Do you heat the oils? Once infused, do you strain out the residual powder or pour it all in the soap?
