Rye Pollen extract supplement questions
Why is rye pollen not found in Prostate Power Rx? Rye pollen extract is known in Europe as Cernilton. This extract has been used for the treatment of chronic prostatitis. So why isn't this ingredient in the prostate formula
   There are many herbs that are used for prostate health and  benign prostatic hyperplasia (BPH), Prostate Power Rx already has several of them, including Serenoa repens and it need not include all.

Cernitin versus Cernilton, what is the difference?
Cernitin pollen extract is a preparation made from eight kinds of pollen and has been used for various prostate diseases in Japan and Europe. Cernitin is a trademarked standardized flower pollen extract from a variety of plants. Cernilton is prepared from the rye-grass pollen Secale cereale.

Are you aware of this herb Cernitin flower pollen? Does it have any sexual enhancement properties? I saw it listed as an ingredient on an herbal libido formula.
   I personally have not tried Cernitin by itself to know whether it enhances libido or other aspects of sexuality.

Research studies
A systematic review of Cernilton (rye pollen extract) for the treatment of benign prostatic hyperplasia.
VA Center for Chronic Diseases Outcomes Research, Minneapolis. BJU Int. 2000.
To systematically review the evidence for the clinical effects and safety of the rye-grass pollen extract Cernilton in men with symptomatic benign prostatic hyperplasia (BPH). Randomized or controlled clinical trials were included if: men with symptomatic BPH were treated with Cernilton (rye pollen extract); a control group received either placebo or pharmacological therapy; the treatment duration was greater than 30 days; and clinical outcomes were reported. In all, 444 men were enrolled in two placebo-controlled and two comparative trials lasting 12 to 24 weeks. Three studies used a double-blind method although the concealment of treatment allocation was unclear in all. Cernilton improved 'self-rated urinary symptoms' (the proportion reporting satisfactory or improving symptoms) vs placebo and another plant product, Tadenan. Cernilton reduced nocturia compared with placebo or Paraprost (a mixture of amino acids); against placebo, and against Paraprost. Cernilton did not improve urinary flow rates, residual volume or prostate size compared with placebo or the comparative study agents. Adverse events were rare and mild. The available evidence suggests that Cernilton rye pollen extract is well tolerated and modestly improves overall urological symptoms, including nocturia. Additional randomized placebo and active-controlled trials are needed to evaluate the long-term clinical effectiveness and safety of Cernilton rye pollen extract.

BMC Urol. 2015. Eviprostat has an identical effect compared to pollen extract (Cernilton) in patients with chronic prostatitis/chronic pelvic pain syndrome: a randomized, prospective study. Previously reported results of a prospective, randomized placebo-controlled study showed that the pollen extract (Cernilton) significantly improved total symptoms, pain, and quality of life in patients with inflammatory prostatitis/chronic pelvic pain syndrome (CP/CPPS) without severe side effects. A phytotherapeutic agent, Eviprostat, is reportedly effective in a rat model of nonbacterial prostatitis.

Testimonial received by email
I heard that Swedish flower pollen extract could increase semen volume and number of orgasmic contractions. I took two capsules a day and after about two weeks I got that result. The number of contractions when ejaculating was at least double what it was before. This effect called "the ropes" lasted as long as I took the pollen. It stopped when I ran out. Of course I have now ordered more! The semen volume increased too. It became thinner and clearer like it was diluted with water. I use Barlowe's Herbal Elixirs 4:1 Swedish Flower Pollen Extract. I like that there are no other ingredients or fillers. Barlowe's Herbal Elixirs 4:1 Swedish Flower Pollen Extract is not as highly concentrated as some other brands, but it is inexpensive and it works.
   A. There are a number of herbs beneficial for sexual health including Tribulus Terrestris Extract and tongkat ali.

Testimonial, report Swedish flower pollen
I have purchased one of your books, and found it to be wonderful. My question is about Swedish Flower Pollen. I have a bottle, by Source Naturals. Its effects are excellent, but it also has kept me awake for hours, after I attempt to sleep. I took the correct dose, one day, then the next day, only one tablet (instead of three ) at noon, and again, could not sleep.- I tried a bottle of the same product about two years ago, and it caused no insomnia.- Two months ago, I purchased another brand, Prostanex, which caused no side effects. However, the company would not assure me, that it is Swedish Flower Pollen, but a similar pollen.I have been in the nutritional life, for 35 years, and could almost be a professional.Source Naturals, nowadays, does not have trained nutritionists, for counsel, which is grievous .Understanding the rules about medical advice, but not able to find anyone else, can you please try to help me figure out why the product is causing insomnia? Its effects are not exactly as a stimulate, like Eulethero, and the Swedish Flower Pollen has created an eventual emotional joy, but I am puzzled, by it causing insomnia.
   A. I have not personally tried these products so I don't know if they have a stimulating effect, but I have found over the years that many herbs have a stimulating and insomnia causing effect even though one does not think of them as stimulants as well known ones such as ginseng.

Q. I am looking to buy Cernilton in Israel! Can you please help?
   A. I am not aware of it being sold in the USA, but I am not sure wether it is available in Israel.
