[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.

Video abstract of Original Research paper “Ulva lactuca polysaccharides prevent Wistar rat breast carcinogenesis through the augmentation of apoptosis, enhancement of antioxidant defense system, and suppression of inflammation” published in the open access journal Breast Cancer – Targets and Therapy by Abd-Ellatef et al.

Background: Recently, several research studies have been focused on the isolation and function of the polysaccharides derived from different algal species, which revealed multiple biological activities such as antioxidant and antitumor activities. This study assesses the possible breast cancer chemopreventive properties of common seaweeds, sea lettuce, Ulva lactuca (ulvan) polysaccharides using in vitro bioassays on human breast cancer cell line (MCF-7) and an in vivo animal model of breast carcinogenesis.
Methods: Cytotoxic effect of ulvan polysaccharides on MCF-7 was tested in vitro. For an in vivo investigation, a single dose of 25 mg/kg body weight 7,12-dimethylbenz[a]anthracene (DMBA) and ulvan polysaccharides (50 mg/kg body weight every other day) for 10 weeks were administered orally to the Wistar rats.
Results: Deleterious histopathological alterations in breast tissues including papillary cyst adenoma and hyperplasia of ductal epithelial lining with intraluminal necrotic materials and calcifications were observed in the DMBA-administered group. These lesions were prevented in the DMBA-administered group treated with ulvan polysaccharides. The immunohistochemical sections depicted that the treatment of DMBA-administered rats with ulvan polysaccharides markedly increased the lowered pro-apoptotic protein, p53, and decreased the elevated anti-apoptotic
marker, bcl2, expression in the breast tissue. The elevated lipid peroxidation and the suppressed antioxidant enzyme activities in DMBA-administered control were significantly prevented by
the treatment with ulvan polysaccharides. The elevated levels of inflammatory cytokines tumor necrosis factor-α and nitric oxide were significantly ameliorated in DMBA-administered rats treated with ulvan polysaccharides as compared to DMBA-administered control.
Conclusion: In conclusion, ulvan polysaccharides at the level of initiation and promotion might have potential chemopreventive effects against breast carcinogenesis. These preventive effects
may be mediated through the augmentation of apoptosis, suppression of oxidative stress and inflammation, and enhancement of antioxidant defense system.
