What is Fadogia Agrestis?

Fadogia agrestis is a short shrubby plant native to Nigeria, but can also be found in areas as far west as Ghana and as far east as Sudan [1]. It is traditionally used as an aphrodisiac and to treat erectile dysfunction [2].

What are the main benefits of Fadogia agrestis?

Fadogia agrestis is best known for its aphrodisiac effects (stimulating sexual desires). A study in rodents suggests that it increases testosterone and acts as a libido enhancer [2]. Based on the degree of benefit, it appears to be one of the more powerful herbs for increasing libido. It appears to be slightly more effective than Spilanthes acmella, based on measurements from rodent studies [3][2].

Evidence in animals supports the pro-erectile properties of this herb, but an associated prolongation of the ejaculatory lesion (sexual endurance) has also been observed.

Some lab studies of the roots of Fadogia agrestis concluded that the components of the roots had inhibitory effects on certain parasites and bacteria, and showed mild antimalarial activity [4].

What are the main disadvantages of Fadogia agrestis?

Researchers have observed changes in testicle size associated with this plant, as well as changes in biomarkers that suggest the plant can damage cell membranes [5]. This phenomenon may not be limited to the testicles, and more studies are needed to determine exactly what is happening.
