[What is Epimedium?]

Epimedium extract is a popular aphrodisiac supplement and herbal sexual performance enhancer.It has a long history of traditional use in China for the alleviation of erectile dysfunction and for improving libido and fertility.

Also known as Horny Goat Weed, this supplement supposedly got its name after a farmer noticed that his flock of goats were particularly aroused after eating flowers of a specific type. These Epimedium flowers contain icariin, which is a natural compound that increases blood flow to sexual organs and promotes sex drive. Icariin has been found to increase Nitric Oxide synthesis as well as inhibiting the activity of the PDE-5 enzyme

[Icariin in Epimedium Extract]

Epimedium extracts powder contain an active phytochemical called icariin.Icariin has been observed to exhibit a number of useful traits, including renoprotective (liver protecting) hepatoprotective (kidney protecting), cardioprotective (heart protecting) and neuroprotective (brain protecting) effects.

It is also an antioxidant and can cause vasodilation. It exhibits antimicrobial characteristics and is thought to act as an aphrodisiac.

Icariin is classified as a flavonol glycoside, which is a type of flavonoid. Specifically, icariin is the 8-prenyl derivation of kaempferol 3,7-O-diglucoside, a prevalent and important flavonoid.

[Function]

1. Combat mental and physical fatigue;

2. Induce vasodilation and improve circulation;

3. Lower blood pressure in hypertensive patients;

4. Improve symptoms of erectile dysfunction (ED) through its action as a PDE5  inhibitor;

5. Improve the use of free testosterone in the blood;

6. Increase libido;

7. Alleviate symptoms of depression and stimulate improved cognitive function;

8. Protect against neurological degeneration.
