This (UG-0014) MICROBE Ultra derives from a Mother tincture of resistant microbes harvested from a Ban Bian Lian culture medium. Similar items, using Huang Lian and Huang Bai, are also separately available. BUT, as a cost-saving measure for you, we also offer a Combination MICROBE Ultra (UG-0035 and UL-0035), derived from a Mother tincture of resistant microbes harvested from a culture medium of all three of the above antimicrobials, which gives you a more broad-spectrum Ultra. Your choice, of course, all depends on your research objectives.
