Aromatase
- an adrenal enzyme that converts androstenedione and estrone to estrogen. Inhibiting its action is one approach to breast cancer prevention and treatment.
Upregulation
1.the process of increasing the response to a stimulus specifically : increase in a cellular response to a molecular stimulus due to increase in the number of receptors on the cell surface.
Another term that is important to grasp is
Agonist
1. a substance which initiates a physiological response when combined with a receptor.
Selective estrogen receptor modulator
*(stimulate estrogen-like action in various tissues)*
Bovine Ovary and White Peony are aromatase upregulators/Agonist while Dandolin would be classified as a SERM ( Selective Estrogen Receptor Modulator aka)

I have done some research on the dandelion root
https://www.meltchestfat.com/what-is-dan...bs-really/
from what i see now i dont want this … “dandelion is know as a armotase inhibitor ..meaning it blocks estrogen ” the root act as a estorgen but it blocks other photoestogens which means opposite effect for a person who wants breast growth-can even be suggest to men for reducing man boobs
Interesting, I remember Lotus recommending it and many others were seeming to have positive effects. I found on websites stating its a phytoestrogen. Perhaps its the greens(Flowers) that cause the anti-estrogen effects but the root itself does not, as the article said Dandelion but never said anything about the root.

Abstract
Plants of the genus Taraxacum, commonly known as dandelions, are used to treat breast cancer in traditional folk medicine. However, their use has mainly been based on empirical findings without sufficient scientific evidence. Therefore, we hypothesized that dandelions would behave as a Selective estrogen receptor modulator (SERM) and be effective as hormone replacement therapy (HRT) in the postmenopausal women.
In the present study, in vitro assay systems, including cell proliferation assay, reporter gene assay, and RT-PCR to evaluate the mRNA expression of estrogen-related genes (pS2 and progesterone receptor, PR), were performed in human breast cancer cells.
Dandelion ethanol extract (DEE) significantly increased cell proliferation and estrogen response element (ERE)-driven luciferase activity.
DEE significantly induced the expression of estrogen related genes such as pS2 and PR, which was inhibited by tamoxifen at 1 μmol·L(-1). These results indicated that DEE could induce estrogenic activities mediated by a classical estrogen receptor pathway.
In addition, immature rat uterotrophic assay was carried out to identify estrogenic activity of DEE in vivo. The lowest concentration of DEE slightly increased the uterine wet weight, but there was no significant effect with the highest concentration of DEE. The results demonstrate the potential estrogenic activities of DEE, providing scientific evidence supporting their use in traditional medicine.

Dandelion T-1 extract up-regulates reproductive hormone receptor expression in mice.

Abstract
Reproductive hormones exert their actions via receptors in diverse tissues. In this study, we examined the expression of estrogen receptors (ERalpha and ERbeta), progesterone receptor (PR), and follicle-stimulating hormone receptor (FSHR) in the adipose tissue and reproductive organs of mice following oral treatment with Dandelion T-1 extract (DT-1E) for 6 weeks.
Quantitative assays by real-time reverse transcription polymerase chain reaction showed enhanced expression of ERalpha and ERbeta mRNA in the adipose tissue of mice fed a diet containing DT-1E compared with the control group fed a plain diet. Furthermore, following gonadotropin injection, higher mRNA expression of ERalpha, ERbeta and PR in the uterus and FSHR in the ovary was found in the DT-1E group compared with the control group. An immunohistochemical study also showed increased levels of the above-mentioned receptors in the DT-1E group.
The present study shows that oral intake of DT-1E up-regulates ERalpha, ERbeta, PR and FSHR expression in mice, suggesting the potential application of DT-1E for the clinical treatment of reproductive hormone-related disturbances.

Please See Table 1

You will notice with this chart they clearly state which plants and funguses are inhibitors and dandelion while it certainly inhibits armoatase it isn't as strong as others.
So it upregulates estrogenic receptors but diminishes aromatase abilities. I wonder how the BO and White Peony respond considering they are extremely strong aromatase upregulators. I guess we need to figure out if upregulating the estrogen receptors is worth the offset? I might be completely wrong as I am no biology major and would need to test this on myself.

I have tested this for myself and noticed that Dandelion helps assist my NBE program so I take it twice a day morning and Evening.
