Niacin
Sexual energy nutrients include the B vitamins. Vitamin B3 also known as Niacin is a water-soluble vitamin that is not stored in the body, and therefore needs to be taken in our diet or supplements. Vitamin B3 is essential for the breakdown of carbohydrates into energy. Niacin regulates the synthesis of sex hormones in your body. A benefit of Niacin is increased mucus secretion, which can further enrich the sexual experience by increasing sensitivities and sensations throughout the body and not just the genitalia. Niacin may also aid individuals that experience difficulty in achieving orgasms. (Morgenthaler, John and Simms, Mia. The Smart Guide to Better Sex From Andro to Zinc, Supplements and Herbs to Fire Up Your Sex Life. Smart Publications, 1999.)

Horny Goat Weed
The provocative name of this herb may not sound serious but in reality,
Epimedium Grandiflorum can provide a serious sexual boost. Horny Goat
Weed has been used in traditional Chinese medicine for over 2000 years. In men, the herb reputedly promotes sexual desire and sperm production, and has been used to treat sexual impotence. In women, the herb has primarily been used to fight fatigue and alleviate postmenopausal hypertension. The chemical ingredients of Horny Goat Weed include a variety of polysaccharides, flavonoid icariin, sterols, and an alkaloid called magnaflorine. Animal research demonstrates that Horny Goat Weed increases testosterone levels. While the exact chemical mechanism for the efficacy of Horny Goat Weed is not yet known, it appears that its ability to increase sexual arousal is linked to the activity of cholinergic neurotransmitters. Additional research has demonstrated that Horny Goat Weed even had sexual potentiation effects and improved the quality of life in patients with chronic renal failure.

Maca
Maca is an ancient herb of the Incas. It has been referred to as “Peru’s
natural Viagra.” Maca or Lepidium meyenii has traditionally been used to
increase stamina, endurance, libido, and sexual potency in men. For women,
Maca has been used to restore hormonal balance and treat a variety of
reproductive and sexual disorders. Modern research appears to substantiate many of the historical claims made for Maca. Active ingredients of Maca include sisoterol, campestrol, ergosterol, brassicasterol, and ergostadienol. Scientific studies have not clearly identified which of the tuber- root’s constituents affect sexual desire and performance, however, recent studies clearly demonstrate the positive benefits of Maca.

“Treatment with Maca resulted in increased seminal volume, sperm count per ejaculation, motile sperm count, and sperm motility.”
(Gonzales G.F, Cordova A.,Gonzales C., Chung A. Vega K., and Villena A. Lepidium meyendi ( Maca) improved semen parameters in adult men. Asian J. Androl; 301-3,Dec 2001.)

“ … Thus it was concluded that both acute and chronic Maca oral administration significantly improve sexual performance parameters in male rats.” (Cicero AF., Banierei E (., and Arletti R. Lepidium meyenii Walp. Improves sexual behavior in male rats independently from its action on spontaneous locomotor activity. J Ethnopharmacol; 75(2-3): 225-9. May 2001.)

“ Oral administration of M-01 and M-02 enhanced the sexual function of male mice and rats, as evidenced by an increase in the number of complete intromissions and the number of sperm-positive females in normal mice, and a decrease in LPE in male rats with erectile dysfunction. The present study reveals for the first time an aphrodisiac activity of L. meyenii, an Andean Mountain herb.” (Zheng BL. He K., Kim CH., Rogers L., Shao Y. Huang ZY., Lu Y., Yan SJ., Qien LC., and Zheng QY. Effect of a lipid extract from lepidium meyenii on sexual behavior in mice and rats.

Zallouh Root
Zallouh root ( Ferulas harmonis), also known as shirsh zallouh, is a small shrub that grows at an elevation of over 6000 feet on Mount Hermon at the joint borders of Israel, Syria, and Lebanon. The powers of this root were purportedly known by King Solomon and the Queen of Sheba. Since biblical times Zallouh has been used as an aphrodisiac. Recent clinical studies validate its efficacy and safety as a treatment for erectile dysfunction in men. The active ingredient appears to be ferulic acid, which dilates blood vessels and stimulates circulation boosting sexual function. Until recently, Zallouh was not available outside of the region in which it is grown. A growing body of scientific research has helped popularize this potent sexual enhancer. Ferulis harmonis has been studied in clinical trials conducted by the Lebanese Society for Urological Studies. Over 7,000 men participated in this research. The overwhelming majority of participants (60 to 86%) experienced a significant increase in libido and improvement in erectile function. Although women have long used zallouh with reputed success, no women participated in these studies. A recent animal laboratory study confirmed the aphrodisiac properties of Zallouh. (Thaher TS., Matalka KZ., Taha HA., Badwan AA. Ferula harmonis 'zallouh' and enhancing erectile function in rats: efficacy and toxicity study. Int J Impot Res;13(4):247-51, Aug 2001.)

Macuna Pruriens
Mucuna pruriens, commonly known as cowitch, velvet bean or dopa bean, contains naturally occurring L-dopa (l-dihydroxyphenylalanine), and has been used by Ayurvedic practitioners for centuries for men with erectile problems and women with low libido. The L-Dopa content provides much of Mucuna’s benefits. Optimizing dopamine levels appears to increase testosterone levels and elevates mood. Dopamine is also used to increase natural human growth hormones. A recent study revealed that the herb is useful in improving sexual performance in men, especially those 50 years and older, who had normal androgen levels. ( Horita H., Sato Y., Adachi H., Suzuki N., Kato R.,Hisasue S., Suzuki K., and Tsukamoto T. Effects of levodopa on nocturnal penile tumescence: a preliminary study. J Androl;19(5):619-24, Sep-Oct, 1998.)
