Note: I do not intend to challenge the credibility of this journal or the authors of this study, but I do want to point out that studies into the beneficial effects of "polyphenols" on whatever biological functions do not get published in the influential journals for a good reason: Almost every herb, and I suppose there are millions, will show some sort of anti-oxidant and I would venture the guess, at the right dose, testosterone boosting or inhibiting effects. For the first 1 1/2 months of 2012, the estimated number of papers reporting novel or summarizing old findings on those natural-antioxidants is >1,400 (according to Google Scholar)... so, chances that the next best herb that is growing just before your door is a "potent antioxidant" (at high enough doses) is ~50%, with another 50% chance of associated increases in testosterone, 25% of all herbs are potential testosterone boosters and "scientifically proven" (at least, in supp-company terms) as soon as a single paper with respective data is published.I guess, now that we have put things in perspective, I can say the magic words that will usually elicit commentaries à la "Where can I get this stuff on the net?" within the next 24h in either the comment area of the respective blogpost or on the SuppVersity's Facebook wall - ready? Then let's go: Treating male Wistar rats with 5mg/kg Rosmaric acid (RA), a polyphenol from herbal plants from the Lamiaceae family, for 40 days increased their total testosterone levels from 1.7 to 2.99ng/ml (+76%)...
|Figure 1: Effects of 40-day treatment with unrealistically high amounts of EMR from 80G EMF (50hz), 5mg/kg rosmaric acid from 1.5g/kg O basilico or a combination of both on endocrine function in male Wistar rats (data calculated based on Khaki. 2012)|
|Figure 2: Intact spermatogonia and spermatocytes in testis of untreated control and after 40-day treatment with unrealistically high amounts of EMR from 80G EMF (50hz), 5mg/kg rosmaric acid from 1.5g/kg O basilico (data calculated based on Khaki. 2012)|
This testbooster should already be in your kitchen cabinet, so no reason to go to GNC
If we discard the questionable data on the exorbitant EMF exposure, this study leaves us with yet another "scientifically proven" testosterone booster, the real advantage of which is that it is naturally present not only in O. basilico, an extract of which was used in this study at a human equivalent dose of 243mg/kg body weight, but also in rosemary (who would have guessed that ;-), Spanish sage, lavender, perilla and lemon balm, majoram, thyme and mint - in other words, all those herbs you should have in your kitchen cabinet, anyway. After all, rosmarinic acid has anti-carcinogenic (Vencatachalam. 2012; Encalada. 2012), neuroprotective (Wang. 2012), anti-... ah, just the same effects as about every other polyphenol at the right dose - and did I mention that it is yet another caffeic acid derivate (cf. Caffeic Acid, AMPK and the Weight Loss Effects of Coffee)?
