Literature overview of Dr. Wolff R&D on experiences with alternative
phytohormone replacement therapy for menopausal problems.
Phytoflavonoids in
menopause and thereafter
The phase of hormonal change in women during menopause is difficult to cope
with both physically and psychologically. The decrease in estrogen levels, which
begins around age 40 to 45, reveals the extremely complicated scope of action of
the hormone estrogen and its derivatives. Apart from vegetative disorders and
the well-known heat flashes and sweats, there are cardiovascular changes, an
increase in bone porosity as well as changes in the skin‘s appearance or regeneration and the reproductive organs.
For a long time, replacement of the missing estrogens by external administration of these hormones seemed the suitable means for eliminating the abovementioned problems. However, the benefit of hormone replacement therapy has
been an item of controversy for several years, since women who receive external
estrogen are subject to an increased risk of breast and uterine cancer. A recently
completed study of the Women‘s Health Initiative (WHI) also ascertained a
slightly increased breast cancer risk for classic hormone replacement therapy.
Due to this experience, physicians are a little more careful today and carefully
weigh the benefits and potential risks of hormone replacement therapy.
A natural alternative to hormone replacement therapy can be found in various
plants. A statistical comparison of the breast cancer risk in Asian and European women has revealed that there are significantly fewer cases in Asia than in
Europe. This surprising result could be connected to the very high consumption
of soy-containing foodstuffs in Asia. The soy plant (Glycine soja) includes socalled secondary botanical active ingredients (genistein) that are able to develop

a weak estrogen effect. Black cohosh (Cimicifuga racemosa) also contains such
phytoestrogens (cimicifugin).
As a matter of fact, it was demonstrated that women‘s menopausal problems
decreased based on the application of soy products. No such undesirable risks
as in estrogen replacement therapy were detected so far. This does not come as a
surprise, if one considers the widespread availability of soy as a foodstuff.
Genistein and cimicifugin are very effective phytoestrogens. Their scope of
efficacy includes the most important areas of antiandrogen properties such as a
reduction in skin aging, bone porosity, cardiovascular improvement, antidiabetic
properties and the antiandrogen protective functions in the hair root.

White tea (Camelia sinensis) is also a valuable source of activating botanical
ingredients. Phytoflavones, polyphenols and trimethylxanthines such as caffeine
complement the antiandrogen active profile with a pronounced antiradical and
cell membrane stabilization properties. When it comes to the tea plant, Asia can
also look back on long-standing experience with phytotherapy, so that efficacy
and tolerability are also guaranteed in this respect.
Also within the hair roots, the antiandrogen effect of the phytoflavones helps

strengthen their resistance and improve the energy supply. In doing so, they support the hair roots‘ growth and regeneration. Menopausal women who measure
their waning estrogen-based protection by the number of lost hairs, can fight this
hair loss effectively and sustainably with phytoestrogen-based active ingredients,
radical catchers and caffeine. They will maintain their hair in a healthy and vigorous condition.
