Click on this link: Xanthoparmelia Scabrosa Extract COA, to view the Certificate of Analysis of this particular batch. Xanthoparmelia Scabrosa is an aphrodisiac and useful for the treatment of erectile dysfunction,  as it induces smooth muscle relaxation allowing for maximum arterial dilation and increased blood flow to the genitals. The Chinese have known for decades that Xanthoparmelia Scabrosa contains substances that greatly inhibit the production of the enzyme Phosphodiesterase-V (PDE-5), allowing for sustained erections. In the body, cyclic Guanosine MonoPhosphate (cGMP) relaxes the muscles around the penis, increasing blood flow, and thus allows a proper erection. PDE-5 binds to and destroys cGMP. If you have erectile dysfunction or have just ejaculated, your levels of cGMP are extremely low because the PDE-5 breaks down the cGMP, weakening your erection. Xanthoparmelia Scabrosa supports healthy erectile function, and due to the fact that it greatly increases blood flow, it is excellent for those seeking the "pump" during exercise. It works in the body similarly to Horny Goat Weed Extract, but may be more effective than Horny Goat Weed for some people. A 2003 study, cited in the research section below, found that certain esters in Xanthoparmelia Scabrosa Extract are toxic to human tumor cells. This study has since oftentimes been misquoted with Xanthoparmelia erroneously being called toxic in general. These vegetable-derived capsules (Vegan, Kosher and Halal certified) are filled by hand with a manual machine, not with a high speed automatic machine, and thus, only pure Xanthoparmelia Scabrosa Extract is in the capsules. Capsules produced with high speed machines in herbal remedy and vitamin "factories" contain several other ingredients, including preservatives because so many bottles of product are produced at one time, and lubricants to ensure that the machines will run faster and more efficiently. Check their labels! Barlowe's Herbal Elixirs is one of the very few manufacturers that still pack their products in glass whenever possible, even though glass is more expensive. Barlowe believes that chemicals can leach out of plastic containers and contaminate the contents, and that the use of glass is much better for the environment. Research: Certain Xanthoparmelia Extract Esters Are Toxic to Tumor Cells Testimonials: Hi. I am the guy who called you about whether or not you had a store front last week. At that time you recommended Xanthoparmelia Scabrosa Extract over the icariin. So I received it and took 2 pills around 7 pm yesterday. An hour and a half went by - nothing except mild disappointment and went to bed, then it kicked in with a vengeance. I never expected this level of potency or duration from an herbal.  Moreover it gives a slight enhancement of sensation all over. I think 100mg of V****a is less potent.  Overall, I am amazed that I will have to reduce the dose of this inexpensive herbal. I'm not sure I can handle feeling like a 17 year old on spring break. Anyway a good time was had by all, repeatedly. And thanks for the Icariin, but clearly I won't need it. Thanks Barlowe.
