Dilemma ~ Using Dried Herbs in Melt & Pour Soap

Hello,
I would like to know any tips on using dried herbs when making soap;
the herbs tend to "bleed" in color after a few days and completely
ruins the appearance. My most recent creation was peppermint soap with
dried mint flakes; the flakes bled out and gave it orange'ish stains
throughout the soap. Any advise on what other methods I can use for
herbs in soap?

Thanks!
