I have been looking into FLAVONOIDS for some time and these two new Oct 2009 article/abstract on Luteolin has caused me to review my past research.
I have done LOTS of research on this stuff. I have found one GOOD Luteolin product, LUTIMAX, but it proved to be too expensive for me to continue taking it. I have talked by phone with the folks at LUTIMAX about the research being done on Luteolin. They have provided me with some of full text articles below.

Luteolin as a therapeutic option for multiple sclerosis.

Multiple sclerosis (MS) remains without an effective treatment in spite of intense research efforts. Interferon-beta (IFN-beta) reduces duration and severity of symptoms in many relapsing-remitting MS patients, but its mechanism of action is still not well understood. Moreover, IFN-beta and other available treatments must be given parenterally and have a variety of adverse effects.
Certain naturally occurring flavonoids, such as luteolin, have anti-oxidant and anti-inflammatory effects, including inhibition of activated peripheral blood leukocytes from MS patients.
Luteolin also inhibits mast cells, as well as mast cell-dependent T cell activation, recently implicated in MS pathogenesis.
Moreover, luteolin and structurally similar flavonoids can inhibit experimental allergic allergic encephalomyelitis (EAE), an animal model of MS in rodents.
An appropriate luteolin formulation that permits sufficient absorption and reduces its metabolism could be a useful adjuvant to IFN-beta for MS therapy.

The study is aimed to determine the role of luteolin (3',4',5,7-tetrahydroxyflavone), alone and in combination with human interferon-beta (IFN-beta), in modulating the immune response(s) of peripheral blood mononuclear cells (PBMCs) isolated from multiple sclerosis (MS) patients.
PBMC proliferation in the presence or absence of these drugs was determined and the production of pro-inflammatory cytokines (IL-1beta, TNF-alpha), and the ratio of cell migration mediator MMP-9, and its inhibitor, TIMP-1 was assessed in the culture supernatants.
Luteolin reduced, in a dose-dependent manner, the proliferation of PBMCs, and modulated the levels of IL-1beta and TNF-alpha released by PBMCs in the culture supernatants.
Luteolin reduced the MMP-9/TIMP-1 ratio via lowering MMP-9 production.
In the majority of cases, luteolin, when combined with IFN-beta, had additive effects in modulating cell proliferation, IL-1beta, TNF-alpha, MMP-9 and TIMP-1.

Here are some GOOD FULL TEXT on FLAVONOIDS that I have found.

I take lots of flavonoid supplements and eat lots of berries/fruits.
I cannot evaluate the VALUE of all this. I just "do-it" because it makes so much sense based upon these studies.
Only certain flavonoids with certain structures seem to help.
