That said, I cannot stress enough that you do not choose Chinese herbal formulas based on symptoms/conditions (for more on this read, "how to choose a formula").

The best formulas are those that are chosen correctly via an appropriate Chinese Medicine diagnosis, ideally through a practitioner (see "Treating the cause and not the symptoms" for more on that).
For cholesterol issues generally, our brief discussion of our acupuncture approach to lowering cholesterol may be interesting to read as well.
