Improvement of postmenopausal depressive and anxiety symptoms after treatment
with isoflavones derived from red clover extracts - Maturitas. 2010
Mar;65(3):258-61 - "assigned to receive two daily capsules of MF11RCE (80mg red
clover isoflavones, Group A) or placebo of equal appearance (Group B) for a
90-day period ... After receiving the MF11RCE compound the total HADS (anxiety
and depression subscale scores also) and the total SDS scores decreased
significantly. This effect was equivalent to a 76.9% reduction in the total HADS
score (76% for anxiety and 78.3% for depression) and an 80.6% reduction in the
total SDS score. After placebo, total HADS (anxiety and depression subscale
also) and total SDS scores also decreased significantly in comparison to
baseline but only equivalent to an average 21.7% decline. CONCLUSION: Red clover
derived isoflavones (MF11RCE) were effective in reducing depressive and anxiety
symptoms among postmenopausal women"

Red clover
extract: a source for substances that activate peroxisome proliferator-activated
receptor alpha and ameliorate the cytokine secretion profile of
lipopolysaccharide-stimulated macrophages - Menopause. 2010 Feb 5 -
"In lipopolysaccharide-stimulated macrophages, red clover extract and its compounds
reduced the secretion of proinflammatory cytokines, interleukin-6 and tumor
necrosis factor alpha, increased the secretion of the anti-inflammatory
interleukin-10, and/or reduced the expression of nuclear factor-kappaB,
inducible nitric oxide synthase, and/or cyclooxygenase 2. Tumor necrosis factor
alpha production was most efficiently reduced by biochanin A and genistein.
Interleukin-6 levels were most efficiently reduced by genistein and equol.
CONCLUSIONS:: Owing to its PPARalpha activation and modulation of the secreted
cytokine profile, red clover extract is a putative candidate for preventing
atherosclerosis and, thus, cardiovascular disease"

The red clover (Trifolium pratense) isoflavone biochanin A inhibits
aromatase activity and expression - Br J Nutr. 2007 Aug 29;:1-8 -
"Biochanin A is an isoflavone isolated from red
clover (Trifolium pratense) ... Isoflavones resemble the structure of
oestrogen, and display agonistic and antagonistic interactions with the
oestrogen receptor. Overexposure of oestrogen is a major contributing factor
in the development of breast cancer ... In the present study the effect of biochanin A on the gene regulation and enzyme activity of aromatase was
investigated. By assaying MCF-7 cells stably transfected with CYP19,
biochanin A inhibited aromatase activity and hampered cell growth
attributing to the enzyme activity"
