Bulbine natalensis


Bulbine natalensis extract is a plant that is native to southern Africa, well-known primarily for its testosterone and libido-boosting benefits. Bulbine natalensis is a succulent plant – one of around 160 species in the Bulbine genus. Bulbine Natalensis has been tested primarily in animals, and initial studies show that the stem of the plant can affect testosterone, luteinizing hormone (LH), which helps with testosterone production follicle-stimulating hormone (FSH), and estrogen levels.

What is Bulbine natalensis used for?

More research needs to be done on the impact of Bulbine natalensis extract in the body, and the precise mechanisms of how it affects the body have not yet been conclusively established. From preliminary research, the plant is thought to act by:

  • Increasing testosterone levels both in the testes and in the blood
  • Increasing the size of the testes due to high testosterone levels which, in turn, boost testosterone secretion
  • Boosting alkaline phosphatase, a testicular enzyme that is essential for maintaining sperm health
  • Raising cholesterol in the testes, which is responsible for making testosterone.
  • Raising the level of compounds needed for maturing and maintaining healthy sperm, including glycogen, sialic acid, testicular proteins)
  • Boosting reproductive hormone levels, both FSH and LH, which then stimulate Leydig cells to produce testosterone.


According to a study done on rats in 2010 and published in the peer-reviewed medical journal, Pharmaceutical Biology, the herb may increase testosterone levels. Taken at the right dosage, Bulbine natalensis effectively increases testicular and serum testosterone concentration. The study also noted an increase in testicular acid phosphatase activity, serum follicle-stimulating, and luteinizing hormone concentrations.

A follow-up study testing testosterone levels in rats found that at the right level of 50mg per kg, there was a corresponding increase of 346% in testosterone.

Testosterone is anabolic so, if channeled correctly, it promotes muscle building. This makes it easier to build lean mass, burn fat, and improve mental acuity. Monitoring and making changes to the body’s level of hormones is vital for muscle growth, moving to the next level in strength training if you have plateaued, and promotes general health. To get the most out of this testosterone booster, Bulbine natalensis is essential to tailor the style of exercise, diet, and nutrition quality, and the amount of sleep.

The findings of the studies on Bulbine natalensis have resulted in a spike in the sports industry’s interest and led to its inclusion in many sports supplements.

Progesterone is most often associated with female reproductive health, but it is also vital for men. It works to counteract estrogen in the male body and be a precursor to testosterone. It is also vital for specific sperm functions such as capacitation. Capacitation is the process by which the outer membrane of the head of the sperm is removed. This ensures that the sperm is ready to penetrate and fertilize the egg.

Progesterone also influences spermiogenesis, which is the final stage of sperm production and testosterone productions.

Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH)

Produced by the pituitary gland, the Luteinizing hormone (LH) forms an integral part of both men’s and women’s reproduction system. In men, its primary role is to stimulate the production of testosterone and the production of sperm. It does this by binding to the receptors on Leydig cells, which are responsible for testosterone production. Low levels of the luteinizing hormone can cause infertility.

Follicle-stimulating hormone (FSH), which is also produced by the pituitary gland, stimulates testicular growth and is necessary for sustaining the health of the maturing sperm cell.

The use of Bulbine Natalensis has also been linked to several other health benefits, including:

  • Assisting the body in fighting diabetes
  • Enhancing muscle development (see Boosts Testosterone Levels benefit)
  • As a remedy for sunburn
  • As a treatment for diarrhea
  • To treat bug stings and mosquito bites.
  • For healing blisters, cold sores, and mouth ulcers
  • To speed the healing of bruises.
  • Helps with erectile dysfunction
  • Increases libido
  • May help with rheumatoid arthritis
