This is about Pueraria and what evidence shows about its properties for bust enhancement and for alleviating menstrual symptoms.
Pueraria is a genus of plant commonly referred to as Kudzu. Fabaceae (or Leguminosae) is the name of the family which Pueraria resides.
Here are some well known plants of Kudzu. Pueraria mirifica is a shortened term for the cultivar Pueraria candollei mirifica, which is also known as Kwao Kreu, Kwao Kreu Kao or Thai Kudzu. Japanese Arrowroot's classification is Pueraria montana lobata, which is often shortened to Pueraria lobata, where "lobata" is its variation name.
Scientific evidence of Pueraria's properties
Pueraria mirifica seems to have a reputation for herbal breast enlargement. This is because it has varying properties that work synergistically together.
There aren't many studies on its effects on hormone levels specifically, however, its effects on the menstrual cycle offers some clues. Pueraria often causes lighter, but longer periods. This suggests that Kudzu has estrogenic, luteinizing hormone (LH) or follicle stimulating hormone (FSH) properties that conflict with prolactin or progesterone properties of this plant.
One research paper suggests that Kudzu has serotonic properties, which is associated with an increase of prolactin, and that it has estrogenic properties. Another research paper determined that Pueraria mirifica did alter menstrual cycles, but didn't appear to affect hormone levels of progesterone, LH, FSH or estrogen. This study didn't include Pueraria mirifica's effects on prolactin. It hypothesized the possibility that its estrogenic, LH or FSH properties balance out levels of progesterone. This appears to be the most likely outcome. Another possibility is that Kudzu's phytohormones or its influence on prolactin weren't tested for in serum samples.
Puerarin is a phytochemical contained in Kudzu with the ability to affect hormones, and receptors of interest. It has acted on Estrogen Receptor Beta (ER-beta), while simultaneously downregulating it. This phytohormone also has raised growth hormone (GH), and prolactin (Prl).
Hormonal properties and their effects vary among different species of Pueraria or Kudzu.
Most herbs do not have the combination of phytohormones that Kudzu has, which gives Pueraria mirifica (Thai Kudzu) a reputation for bust enhancement.
Kudzu's reputation to alleviate menstrual problems can be attributed to its hormonal effects as described in the previous section.
While Pueraria mirifica root is believed to be effective for natural breast enhancement, most standardized studies have shown Kudzu's hormonal effectiveness based on cancerous breast cell samples. Kudzu is likely not carcinogenic, but it seems to not discriminate between nurturing healthy and tumorous cells. Pueraria is still very useful, when used in small portions and when not used in cases prone to cancer.
The best time to use Kudzu root for breast enhancement is during menstruation. Various species and varieties of Pueraria can be used interchangeably, but their potencies will vary. A combination of herbs with anti-cancer properties can enhance or replace Kudzu's effects for maximum breast enhancement benefits.
