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 (ERβ): agonists often simultaneously downregulate the receptor they act upon. 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.
Avoid pueraria completely during proliferative phase, because it can especially contribute to hot-flashes and hirsutism here. Pueraria can possibly be used in minimal amounts is during menstruation or late secretory phase, but it likely requires a companion herb for improved effects. Pueraria by itself during menstruation has the same effect as the herb combination of spearmint and clover, which causes minor breast growth, but additional body hair. The effect of spearmint and clover implies that the effect is positive and estrogenic on ERα in the breasts (and fallopian tubes), but androgenic on ERβ in the reproductive tract. Kudzu also has many of the same phytochemicals as clover, so it likely behaves as spearmint with clover together. Kudzu may be more effective by itself during late secretory phase, but it has potential to disrupt the cycle then.
Different species and cultivars of kudzu have different strengths of promoting or lowering menstruation, which can disrupt the menstrual cycle at other times. Hops and spearmint can be used together in minimal amounts and in different ratios to balance menstruation intensity.
While Pueraria mirifica root has been effective for natural breast enhancement, most standardized studies have shown Kudzu's hormonal effectiveness based on cancerous breast cell samples. Pueraria 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.
Kudzu is to be avoided for those with hot-flashes or hirsutism.
If you have hirsutism, PCOS, hot-flashes, other signs of hormone imbalances, see estrogen-imbalance and treating hirsutism program before trying herbs. See precautions for more details of care to be taken with herb use. Also, check for the latest blog updates about herb and hormone safety.
Herb concentrates can be tens of times more potent by weight than herbs in solid form. This can easily lead to hormone imbalances. For this reason, concentrate extracts are not recommended for extended or excessive internal use, especially during fertility years. Concentrates shouldn't be used to overcome plateaus. Another issue with herbal extracts, is that they may not have the full range of properties of the herb. If opting to use herb extracts, use no more than 1 drop at a time, diluted in a food-grade carrier oil (like unrefined olive oil) or water.
Biology describes the science of breast development and endocrinology. Symptoms related to hormone imbalances are important to understand. The text from Biology and Hormone Imbalances is in breast-endocrinology.pdf, which uses a Creative Commons license.

Herb timing and combinations' success for breast enhancement relies on menstrual phases. See programs for examples of herb combination use, and for pictures of successful herbal breast enlargement.
