Lepidium meyenii herb research
Lepidium meyenii, also known as maca, is a root-like vegetable shaped like a radish that grows high in the harsh climate of the Andes Mountains in South America at elevations up to 15,000 feet. For more than two millennia, native Peruvians have used Lepidium meyenii root as food and medicine, to promote endurance and improve energy, vitality, sexual virility and fertility. If you have an interest in increasing energy, an excellent supplement is MultiVit Rx which works better than Lepidium meyenii alone. Lepidium meyenii is found in Passion Rx, an herbal product used for female impotence and as a treatment of impotence in males. Lepidium meyenii is the botanical name for maca herb.
Lepidium
meyenii root and sexual desire
Feeding high dosages of Lepidium meyenii root extracts to normal male mice
increase the frequency
with which they couple with female mice. Human studies with Lepidium meyenii herb indicate Lepidium meyenii supplementation leads to enhanced sexual desire.

The aim of this study was to evaluate the chronic effect of different varieties
of Lepidium meyenii (Red Maca, Yellow Maca and Black Maca). Male rats were
treated by gavage with aqueous extract of each variety of
Lepidium meyenii for 84 days. At the end of the treatment,
daily sperm production (DSP), epididymal sperm count (ESC) and sperm count in
vas deferens (SCVD) were assessed. In addition, testis DNA quantification was
also determined. Any toxic effect was assessed in liver and spleen by
histological studies. The results indicate that Yellow
Lepidium meyenii
and Black Lepidium meyenii
improved ESC and that three varieties of
Lepidium meyenii
increased the SCVD without
affecting DSP. Moreover, testis DNA levels were not affected by treatment with
any of the three varieties of Lepidium meyenii. Histological picture of the liver in animals
treated with the three varieties of Lepidium meyenii
was similar to that observed in
controls. In conclusion, Yellow and Black
Lepidium meyenii
increased epididymal sperm count
after 84 days of treatment without affecting DSP.
Lepidium meyenii
seems to act as a
modulator of sperm count at the reproductive tract level.
Lepidium meyenii and hormone
levels
Lepidium meyenii (Maca) does not exert direct androgenic activities.

Maca is the edible root of the Peruvian plant Lepidum meyenii, traditionally
employed for its purported aphrodisiac and fertility-enhancing properties. This
study aimed at testing the hypothesis that Lepidum meyenii contains
testosterone-like compounds, able to bind the human androgen receptor and
promote transcription pathways regulated by steroid hormone signaling. Lepidum
meyenii extracts (obtained with different solvents: methanol, ethanol, hexane
and chloroform) are not able to regulate GRE (glucocorticoid response element)
activation.
Lepidium meyenii questions
Q. I take Sotalol 120mg BID, and would like to try
Lepidium meyenii 300mg with 500mg goat weed for erectile dysfunction. My doctor approved Viagra 100mg which does not provide a solution.
A. Sotalol is used to treat irregular heartbeats. Sotalol is in a
class of medications called antiarrhythmics. It works by acting on the heart
muscle to improve the heart's rhythm. If a person has heart rhythm problems,
they should very very careful using sexual enhancing herbs such as horny goat
weed or perhaps even high dosages of Lepidium meyenii since aphrodisiac herbs
can sometimes stimulate the heart the beat faster and this may cause heart
palpitations.
