It's just possible interactions. 
" According to Jaroslav Drsata, a scientist in the Czech Republic, the enzyme-blocking properties of saw palmetto may include aromatase ".
If this is true, Shouldn´t SP be better as anti-androgen for the girls with estrogen dominance ? after all spearmint reduces testosterone but also increases estrogen.
Hi Cecil, sorry for the info overload.
When searching for SP you come up with wide range of opinions and studies and mostly with the same methodologies. Below it's listed an interaction when taking with estrogen pills.
Saw palmetto seems to decrease estrogen levels in the body. Taking saw palmetto
along with estrogen pills might decrease the effectiveness of estrogen pills.
Some estrogen pills include conjugated equine estrogens (Premarin), ethinyl estradiol, estradiol, and others.

And of that:
Maintaining endogenous testosterone (T) levels as men age may slow the symptoms of sarcopenia, andropause and decline in physical performance. Drugs inhibiting the enzyme 5alpha-reductase (5AR) produce increased blood levels of T and decreased levels of dihydrotestosterone (DHT). However, symptoms of gynecomastia have been reported due to the aromatase (AER) enzyme converting excess T to estradiol (ES)

Searching for SP within our forum I came across this post from chrishoney, who is a medical professional who's opinion I trust and respect!

The article itself also says that SP is likely ineffective in treating BPH but if you dig into the research, it turns out there is NO standard way of producing/extracting SP into capsules so comparing one brand to another or even production lots within a single brand is impossible. There is too much variance in the amount/strength of the likely active component of SP (lipidic liposterols). There is a company in the EU that prepares a standardized preparation lipidic liposterols derived from SP and the evidence shows it has significant effect on BPH symptoms (Permixon, Pierre Fabre Médicament, Castres, France).
Doing a search on "antiestrogenic effects of saw palmetto" on scholar.google.com yields similar results. The anti-estrogenic activity has been noted in prostatic tissue, not "in the body" as stated in several places in the article. To further complicate things, SP apparently has both anti-androgenic AND anti-estrogenic effects experimentally.
My personal experience is that PM worked just fine without the use of SP. I can't say that SP had NO effect or that it opposed PM, just that PM alone, worked fine.
Concerning the Czech scientist I couldn't find when his research was done, but his theory does raise the question for more debate. We need to open our minds up to the possibility of new information when it comes to NBE. Some see it as a nuisance and shouldn't be entertained for discussion, that's ok!. If you're getting results with your NBE great, don't mess with it, but between you and me I'd like to make sure that I didn't leave more than a B-cup on the table. So if there's new studies, research that might be working for somebody else I'd like to know!. Ideally, providing two sides to each theory is best for our purposes in regards for NBE.
Quote:Just done some digging, it seems out of all the teas peppermint has the strongest estrogenic increasing and testosterone decreasing activity.
“Among them, the extract of peppermint tea exhibited the highest estrogenic activity.”

“After five days, the women’s levels of free testosterone (the biologically active form) declined, although their total testosterone level stayed the same. Women’s levels of luteinizing hormone, follicle stimulating hormone, and estrogen rose, while their triglyceride levels dropped significantly…The researchers found a significant decrease in free (active) testosterone in the blood and an increase in several female hormones including follicle-stimulating hormone.”

(Note: this doesn’t mean the above study would necessarily have the same effect in men)
“After treatment with spearmint teas, there was a significant decrease in free testosterone and increase in luteinizing hormone, follicle-stimulating hormone and estradiol.”

Of spearmint and peppermint, peppermint is higher in estrogenic properties

Take care Ceci,
btw, have you heard of this? (it is important to know that only 5% of testosterone is transformed into DHT.)
