Passion Rx with Longjack extract
Tongkat Ali (Eurycoma longifolia jack, also promoted as Longjack) is a small tree
found in the jungles throughout Malaysia and Southeat Asia. Natives
consider every part of the tree as medicine. In southeast Asia, Longjack is used as a tonic, to treat
malaria, and as an aphrodisiac. Not enough human research has been done to
determine how effective longjack is for the treatment of malaria.
In the old days, the
longjack roots had to be brewed for long hours to
get a bitter extract. Now longjack is conveniently
packed in pill or "tea-bag" form and mixed with regular coffee or tea. Lonjack, in the form of coffee and tea is now sold in Malaysia's ubiquitous roadside hawker stalls,
and supermarkets. I will use the
term longjack and tongkat ali interchangeably.
Tongkat Ali ( Longjack ) - Aged root
powder and LJ100 Longjack extract
You
have the option to atake Longjack root
powder supplement, LJ100 Longjack extract supplement, or preferably Passion Rx which is an
effective combination of both, plus more than a dozen
aphrodisiac herbs. It is difficult to predict in any one individual which product will work best.
The surest way is to try them separately to see which one is most suitable to
your own body chemistry. Passion Rx has a very high rate of reorder.
Longjack supplement facts -
Longjack root powder - 200 mg (Eurycoma Longifolia Jack)
Longjack LJ100 - 25 mg extract, (Eurycoma Longifolia
extract)
Suggested Use: As a dietary supplement, take one Longjack root powder
capsule or one LJ100 capsule in the morning before breakfast or as recommended by your health care
provider. For long term use, take every other day day with a full week off
each month. Results
may vary depending on age and metabolism. Longjack side effects are more common with higher
dosages. It may be preferable to take lower doses of Longjack and have it work slower in order to avoid the longjack side effects mentioned
below.
Longjack side effects
I have read articles in health magazines promoting Longjack that it has
wonderful benefits with absolutely no side effects. This is not my experience. Even
though Longjack is quite useful as an herbal aphrodisiac, it does have
shortcomings.
One of the side effects of high dose Longjack root powder or Longjack extract is that it can cause insomnia.
Lack of adequate sleep, when repeated over many days, can lower sex drive. So,
it's better to take smaller amounts over a few day period than a very high
amount in one day.
I have personally tested Longjack powder and several Longjack extracts in different dosages and realized that it has additional
side effects not often mentioned in articles or in research papers. Many of my
patients have given me feedback regarding their personal experiences
with Longjack. I am convinced that high doses can cause increased body
temperature, which is not a good thing during hot and steamy days without air
conditioning, but a good thing if you live in Alaska or enjoy taking a walk
outside in cool weather. Some people find that when they take a high dose, they
become restless and impatient, perhaps easily angered. Therefore, you don't want
to swallow several capsules of Longjack if you expect to be driving in heavy
traffic. So, being patient and taking lower doses is the preferred option.
Passion
Rx---
Formulated
by Ray Sahelian, M.D. for Men and Women with Longjack root and extract
Passion Rx provides results that are noticed within two to four
days, and improve over several days of use. Our feedback
thus far indicates more than 80% user satisfaction by the end of the first week
and 90 percent by the end of the second week.
Dr. Sahelian and his research staff have tested various doses and extracts of
dozens of herbs from a number or raw material suppliers to determine the ideal
dosage and combination for optimal aphrodisiac properties with the fewest side
effects. After years of
research, an effective proprietary
blend with several herbal extracts from the best raw material suppliers has been
developed. This unique aphrodisiac blend is a
close kept secret only known to the doctor and his research staff. You will only find this exact combination in Passion Rx.
In recent years science has made breakthroughs in
the understanding of sexual dysfunction. But, for hundreds of years,
civilizations around the world have known about locally grown herbs that achieve
wonderful results with far fewer side effects than prescription drugs.
The potent herbal extracts in Passion Rx include ashwagandha, catuaba, cnidium monnieri,
coleus forskohlii, horny goat weed,
longjack, maca, mucuna pruriens, muira puama, passion flower,

What the research says about Longjack:
Aphrodisiac benefit
Over the past few years, there have been quite a number of studies that have
shown longjack to have sex-boosting properties. The effects of longjack
were studied on the libido of male rats after giving them with several dosages
of longjack daily for 10 days. Results showed that longjack
produced a dose-dependent increase in mounting frequency, that is, the number of
times the male rats tried to mount the female rats increased as the dose given
to the rats increased. In addition, the rats displayed more frequent and
vigorous licking and anogenital sniffing towards the receptive females.
Furthermore, the rats dosed with longjack spent more time grooming their
genitals compared to the rats who were not given the plant. Genital grooming may
be interpreted as masturbation. The researchers noticed another interesting
finding: while the rats who had not received the plant showed normal behavior
within the cage such as exploration and climbing the cage wall, the rats
given longjack stayed around the females instead of exploring the cage.
Longjack also increased the frequency of the rats' erections.
Longjack and cancer treatment
Beta-carboline alkaloids isolated from longjack, have demonstrated
significant cytotoxicity against human lung cancer (A-549) and human breast
cancer (MCF-7) cell lines. How useful longjack or longjack extract would be in
treating or preventing human cancer is not known at this time.
Longjack and malaria
Interestingly, scientists have found that, in addition to
its sex-enhancing effects, compounds within longjack have anti-malarial
properties.
Longjack mechanism of action
Very little is known regarding the mechanisms of action of
longjack.
Recent studies indicate that the root contains several compounds including beta-carboline
alkaloids and quassinoid-type glycosides. How these compounds and many others in
tongkat ali influence the human sexual response is not clearly understood at
this time. I have read promotional material by some vitamin companies regarding longjack that it enhances testosterone production, and this may be true, however I have not been
able to definitively confirm this claim. Even if longjack powder or longjack
extract do stimulate or help release testosterone, we don't know at this time
whether this would continue over time or whether testosterone supply would be
used up with repeated, daily longjack use.
Longjack
availability
Tongkat ali is sold as a powder, and in capsules, sometimes mixed with other
herbs. There are a number of longjack extracts available in various potencies, and since
each company will have a different way of extracting, it is difficult to give
dosages that would be consistently effective.
Longjack
side effects
High doses of
longjack cause insomnia and increased body temperature along with
restlessness and irritability.
Long term side effects of Longjack on human health are not known. Do not take
longjack more than 2 or 3 days in a row.

Longjack research update
Eurycoma longifolia Jack - longjack - enhances sexual motivation in middle-aged male mice.
J Basic Clin Physiol Pharmacol. 2003;14(3):301-8.
Longjack was investigated for sexual
motivation activity in adult, middle-aged male mice and in retired breeders,
using the modified open field and the modified runway choice methods. Each mouse
received 500 mg/kg of one of 4 fractions of
Longjack, viz. chloroform, methanol, butanol,
and water, whereas the mice in the control and yohimbine groups received 3 ml/kg
of normal saline and 30 mg/kg of yohimbine daily respectively for 10 d. The
results show a transient increase in the percentage of male mice responding to
the right choice after chronic consumption of the fractions with 50 percent of
the adult middle-aged male mice treated with
Longjack and yohimbine scoring the right choice
after 8 and 5 days post-treatment respectively. In conclusion, this study has
shown that
Longjack continues to enhance sexual
motivation in adult, middle-aged male mice and in retired breeders.
Cytotoxic and antimalarial constituents from the roots of Eurycoma
longifolia - longjack.
Bioorg Med Chem. 2004 Feb 1;12(3):537-44.
Sixty-five compounds were isolated from the roots of
Longjack. Among these isolates, four quassinoid diterpenoids were reported
from natural sources for the first time, namely eurycomalide A, eurycomalide
B, 13beta, 21-dihydroxyeurycomanol, and 5alpha, 14beta,
15beta-trihydroxyklaineanone. Certain ompounds demonstrated strong cytotoxicity
toward human lung cancer (A-549) cell lines and others toward human breast cancer
(MCF-7) cell lines. Two compounds displayed potent antimalarial activity
against the resistant Plasmodium falciparum.
Effect of Eurycoma longifolia Jack - longjack extract - on libido in middle-aged male rats.
J Basic Clin Physiol Pharmacol. 2002;13(3):249-54.
The effect of increasing doses of various fractions of longjack
extracts on libido was examined in middle-aged male rats. The results showed
that a high dose (800 mg/kg) of all
longjack extracts significantly
increased mount frequency over that of untreated controls, but had no effect on
the frequency of intromission or ejaculation. The results of this study
show that longjack extracts can increase libido in
middle-aged male rats.
Longjack emails
Q. Are components of LJ100 ( longjack extract ) closely enough related to
testosterone or androstenedione that my wife ought to consider not taking LJ100
to be on the "safe side" of developing breast cancer?
A. We are not in a position to say whether a person
should or should not take a particular supplement. As to Longjack LJ100, if it
does release testosterone, it most likely is transient as opposed to a constant
amount that is normally present in the bloodstream. Furthermore, Longjack should
not be used every day, perhaps 2 or 3 days a week.
Q. Can you tell me about longjack extract?
A. Longjack is available in various extracts, including regular powder, 20:1
extract, 50:1 extract, and 100:1 Longjack extract. We don't see any reason
to use higher concentrations of longjack, such as a 200:1 Longjack extract.
Q. Is longjack helpful in women with
female sexual
dysfunction?
A. As long as low dosages are used, longjack could be
appropriate for women with female sexual dysfunction.
