Bulbine Natalensis is an herb, indigenous to South Africa, which has recently been studied for its use as a Libido enhancer, testosterone booster, and estrogen reducer. It has also been studied as an herbal remedy for erectile dysfunction.

Colloquially it is known as Ibhucu (Zulu), Rooiwortel (Afrikaans). It is an evergreen perennial (grows throughout the year), and features broad sharp pointed fleshy yellow-green leaves. It has clusters of star-shaped yellow flowers on long thin flowering stems, and is drought resistant, typically growing in Full Sun or semi shaded areas.

In traditional folk medicine, the leaves, roots, and sap are all used respectively for a variety of ailments: to treat bug stings, mosquito bites, blisters, cold sores, mouth ulcers, cracked skin, to soothe sunburn, disinfect cuts, and to speed the healing of bruises.

Is there any scientific research to support its use as a testosterone booster, and/or estrogen reducer?

Yes. A rodent study was performed by the Centre for Phytomedicine Research, Department of Botany, University of Fort Hare, Alice, South Africa. Rodents receiving Bulbine Natalensis had a serum testosterone level equal to 347% of the control group; in that same group, estrogen was 35% lower.

Has Bulbine Natalensis ever been used to raise testosterone and lower estrogen in humans?

Although this herb is new to the market, it has been successfully used to boost testosterone levels in humans, while lowering estrogen levels. While no clinical studies have been performed examining these effects in humans, its use has been validated in non-clinical settings.

Does Bulbine Natalensis improve Libido?

In a rodent study conducted by Yakubu and Afolayan, test subjects receiving Bulbine Natalensis were found to have significantly elevated libidos, when compared to the control group.


How effective is Bulbine Natalensis on erectile dysfunction?

Although human trials have not yet been performed on Bulbine Natalensis, the initial rodent data suggests that it has the potential to outperform the leading erectile dysfunction drug.

Is Bulbine Natalensis available as a nutritional supplement?

Phytoserms-347 is the first nutritional supplement in the world to contain Bulbine Natalensis. It uses a chemically fingerprinted and standardized version of the herb, trademarked under the name Prolensis. This ensures that from batch to batch, the potency of the product doesn’t fluctuate, as is sometimes seen with various herbal products.


Are there any known fake or counterfeit Bulbine Natalensis products?

Unfortunately, the demand for this herb has increased faster than the production, which resulted in a situation where lower quality and potency Bulbine Natalensis has entered the supply chain. In some cases, it is suspected that similar-looking herbs from the same genus (i.e. Bulbine Fructescens, Bulbine Latifolia, etc...) are mistakenly being harvested and sold as Bulbine Natalensis. This is why Phytoserms-347 contains Prolensis, the first and only standardized Bulbine Natalensis in the world, harvested and imported directly from South Africa.

Is Bulbine Natalensis safe?

Although no human trials have taken place, it has been used extensively in South Africa for centuries, and no adverse effects have been reported from contemporary use in a nutritional supplement.

Who could benefit from using Bulbine Natalensis as a dietary supplement?

Athletes looking to enhance their hormonal profile, support a healthy endocrine system, or improve their recovery, can all benefit from the use of this herb in a dietary supplement. Additionally, those looking to improve their Libido or experience prosexual effects, could potentially benefit from Bulbine Natalensis.

How should Bulbine Natalensis be stored?

Although there is no universally accepted protocol for the storage of this herb, it should likely be stored in a clean, dry place, below room temperature if possible. This insures that the Bulbine maintains potency of its sterols and sterolins.

How much should be taken? Are there any side effects?

The dose of Bulbine Natalensis found in each daily serving of Phytoserms-347 is equal to the amount shown to maximally elevate testosterone and lower estrogen.
