Muira puama in the treatment of erectile dysfunction
The term "impotence" has traditionally been used to
signify the inability of the male to attain and maintain
erection of the penis sufficient to permit satisfactory
sexual intercourse. Impotence, in most circumstances, is
more precisely referred to as erectile dysfunction as this
term differentiates itself from loss of libido, premature
ejaculation, or inability to achieve orgasm.
An estimated 10 to 20 million men suffer from
erectile dysfunction. This number is expected to increase
dramatically as the median age of the population increases.
Currently, erectile dysfunction is thought to affect over
25% of men over the age of 50.
Although the frequency of erectile dysfunction
increases with age, it must be stressed that ageing itself
is not a cause of impotence. Although the amount and force
of the ejaculate as well as the need to ejaculate decrease
with age, the capacity for erection is retained. Men are
capable of retaining their sexual virility well into their
80's.
Erectile dysfunction may be due to organic or
psychogenic factors. In the overwhelming majority of cases
the cause is organic, i.e., it is due to some physiological
reason. In fact, in men over the age of 50, organic causes
are responsible fro erectile dysfunction in of 90%. In the
past, a man with impotence who was able to have nighttime
or early morning erections was thought to have psychogenic
impotence. However, it is mow recognized that this is not a
reliable indicator.
Preliminary research indicates one of the best
herbs to use for erectile dysfunction or lack of libido may
be Muira puama (also known as potency wood). This shrub is
native to Brazil and has long been used as a powerful
aphrodisiac and nerve stimulant in South American folk
medicine . A recent study has validated its safety and
effectiveness in improving libido and sexual function in
some patients.
At the Institute of Sexology in Paris, France,
under the supervision of one of the world's foremost
authorities on sexual function, Dr. Jacques Waynberg, a
clinical study with 262 patients complaining of lack of
sexual desire and the inability to attain or maintain an
erection demonstrated Muira puama extract to be effective
in many cases. Within two weeks, at a daily dose of 1 to
1.5 grams of the extract (4:1), 62% of patients with loss
of libido claimed that the treatment had dynamic effect
while 51% of patients with "erection failures" felt that
Muira puama was of benefit. These results are extremely
promising and seem to indicate that Muira puama may provide
better results than yohimbine without side effects.
Presently, the mechanism of action of Muira puama
is unknown, From the preliminary information, it appears
that it works on enhancing both psychological and physical
aspects of sexual function. Future research will
undoubtedly shed additional light on this extremely
promising herb for erectile dysfunction.
Yohimbine in the treatment of erectile dysfunction
The term "impotence" has traditionally been used to
signify the inability of the male to attain and maintain
erection of the penis sufficient to permit satisfactory
sexual intercourse. Impotence, in most circumstances, is
more precisely referred to as erectile dysfunction as this
term differentiates itself from loss of libido, premature
ejaculation, or inability to achieve orgasm.

the cause is organic, i.e., it is due to some physiological

are responsible fro erectile dysfunction in of 90%. In the
past, a man with impotence who was able to have nighttime
or early morning erections was thought to have psychogenic
impotence. However, it is mow recognized that this is not a
reliable indicator.
The only FDA approved medicine for impotence is
yohimbine - an alkaloid isolated from the bark of the
yohimbe tree (Pausinystalia yohimbe) native to tropical
West Africa. Yohimbine hydrochloride increases libido, but
its primary action is to increase blood flow to erectile
tissue. Yohimbine is a selective alpha-2 receptor
antagonist. Contrary to a popular misconception, yohimbine
has no effect on testosterone levels.
When used alone, yohimbine is successful in 34% to
43% of cases. It is effective in both psychogenic and
organic cause of impotence. The standard dose of yohimbine
is 15 to 20 mg per day, however, higher doses, up to 42 mg
of yohimbine, may prove to be more effective.
To illustrate the benefits to be expected in
clinical practice, let's examine the results from one of
the more recent double-blind studies. In the study, 82 men
with erectile dysfunction selected from a Veterans
Administration population with a high incidence of diabetes
and vascular disease underwent a multifactorial evaluation,
including a determination of penile brachial blood pressure
index, caver nosography, sacral evoked response,
testosterone and prolactin determination, sexual
dysfunction and arousal test.
After one month of treatment with the maximum of
42.0 mg oral yohimbine hydrocholride daily 14% of the
patients experienced restoration of full and sustained
erections. 20% reported a partial response to the therapy
and 65% reported no improvement. In comparison, only three
patients reported a positive effect in the placebo group.
Maximum effect with yohimbine takes two to three weeks to
manifest itself. Yohimbine was active in some patients
with arterial insufficiency and a unilateral sacral reflex
arc lesion, and in one with low serum testosterone levels.
The 34% response is somewhat encouraging given the study
population.
Side effects often make yohimbine very difficult to
utilize. Yohimbine can induce anxiety, panic attacks, and
hallucinations in some individuals. Other side effects
include elevations in blood pressure, and heart rate,
dizziness, headache, and skin flushing. Yohimbine should
not be used in individuals with psychological disturbances.
Although crude yohimbe bark preparations are
available commercially, use of pure yohimbine hydrochloride
is preferred. There are no commercial sources of yohimbe
bark that are available to physicians or in health food
stores which actually state the level of yohimbine per
dosage. Without knowing the content of yohimbine, it is
virtually impossible to prescribe an effective and
consistent dosage. Because of the yohimbine content of
yohimbe bark, the FDA classifies yohimbe as an unsafe herb.
