This is a powerful extract which has been extracted with cold water from Bulbine Natalensis stems only, and then freeze-dried, following the guidelines of the original research techniques.  Click on this link: Bulbine Natalensis COA, to see the Certificate of Analysis on this particular batch. Bulbine Natalensis, an herb native to South Africa, may in small dosages substantially and quickly increase Testosterone in humans, while at the same time reducing Estrogen levels. These vegetable-derived capsules (Vegan, Kosher and Halal certified) are filled by hand with a manual encapsulation machine, not with a high speed automatic machine, and thus, only pure, unadulterated Bulbine Natalensis 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! Also, 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. Bulbine Natalensis is an herb which has received a lot of attention in the past months. It appears to have great potential as a  libido/Testosterone boosting supplement. Although there are several good herbal extracts for boosting Testosterone, Bulbine Natalensis seems to be the only one which at the same time lowers Estrogen levels. Even though several Bulbine studies are mentioned on the internet, the only published one Barlowe's has been able to find a link to is shown below.  It is reported, however, that a rodent study performed by the Centre for Phytomedicine Research, Department of Botany, University of Fort Hare, Alice, South Africa found that rodents receiving Bulbine Natalensis water extract had on average a Serum Testosterone level equal to 347% of the control group that did not receive Bulbine, and that their Estrogen levels were 35% lower. A recent non-clinical study showed that a 36 year old male weighing 75 kilograms over a two week period taking 360 milligrams of 5:1 Bulbine Natalensis cold water extract increased his total and free Testosterone levels by 35.5%. The study linked to below found that Bulbine substantially increased the libido of male rats. Barlowe's Herbal Elixirs is offering this high quality 5:1 Bulbine Natalensis Extract in 360 milligram capsules. 360 milligrams appears to be a fairly standard dosage level. The capsules contain only Bulbine Natalensis Extract with absolutely no other adulterants or fillers. Bulbine probably should not be taken by those inexperienced with herbal testosterone boosters. Barlowe's is only offering this product in order that  those interested may experiment with and test Bulbine Extract in its pure form. It does appear that 360 milligrams daily may be too high a dosage for some people for optimal results. These capsules may be easily separated  so that a lesser dosage may be taken. Research: Bulbine Appears Safe and Increases Libido and Reproductive Hormones in Male Rats Caution: Barlowe's Bulbine Natalensis Extract uses only the finest quality 5:1 freeze-dried, cold water Extract from the most trusted South African supplier. This superb herbal extract is generally safe, but it is potent and should be utilized with care. Do not exceed one capsule daily until you have exensively tested your results using one 360mg capsule daily.  Those of light body weight initially may want to open the capsule and split one capsule's contents between two days. This product is for dietary use. If side-effects occur, discontinue use immediately! The above statements have not been evaluated by the Food and Drug Administration (FDA). This product is not intended to diagnose, treat, cure, or prevent any disease. Directions For Use: Take only one (360 mg) capsule daily, unless you have a high body weight.  Cycle usage - for example, two weeks on, one week off. Less is more with this extract.  Results follow a bell-shaped curve. Testosterone continues to increase up to a certain mg dosage, but if that dosage is exceeded,  results lessen substantially. Results and usage amounts may vary based on body type and weight. Bulbine Natalensis 5:1 Extract PRICE: $18.95 for each 60 capsule bottle (360 mg per capsule)
