Chasteberry an anti androgen?
March 1 2006 at 8:51 PM SugarQ (no login)
--------------------------------------------------------------------------------
supposedly it is suppose to lower prolactin levels and by doing so can it work as an anti androgen.
jut to clarify for anyone that is interested. High Prolactin levels inhibits aromatization which is where testosterone gets converted into estrogen. so if chasteberry works to lower prolactin then theoretically it should lower testosterone levels two right?
i know this seems complicated when we all want higher prolactin levels for nbe. its hard to expain what im trying to do here. idont want anyone to worry about what they are doing just yet but for anyone with a high androgen problem i think we may got some issues.NBE may be a little bit more difficult.
im hoping molly would help me out here but if anyone has any insite i would be so glad to hear your opinions.

To my knowledge the Chastenberry is an anti-androgen,can be an SP alternitive and Ive never been big on the theory of raising Prolactin levels even though its ofton recommened for BE simply b/c Prolactin in general can be a "stresser" and therefore possibly not so great for BE anyway.

Is there a difference in "raising" prolactin levels and a prolactin "stimulator"? Or is it the same thing?

I have high androgen levels and I took vitex while doing NBE together with SP and Fenugreek, I never actually considered that it was an NBE herb until I read about it here just now :-).
Since I started taking it app. two weeks after I began my single herb routine I couldn't say if it made a difference, all I know is that I seem to be growing now fine without it, but I will have to see further into my routine how well I grow without it and if I might want to add it again.
The only reason I added it in the first place was because I was trying to get my hormone levels sorted out and a guy working in a health store told me that the vitex might just regulate them and maybe even get them back on track.
I think I better add this to my routine's page, I totally forgot all about taking it, I only remembered there and saw it when I went through my notes.
For anyone considering to take it, you aren't meant to use it long term, so 3-6 months is apparently ok but you aren't meant to take it any longer than that.

well, you dont need elevated Prolactin to grow but it does help alot. prolactin works to inhibit testosterone conversion so if you got excess androgen its better not worry about doing massages and anything that increases prolactin. you may not need high dosages of fenugreek. maybe 1500mg the max. if you got excess androgen then you have low estrogen levels so its better to get those levels under control first before you add anything to increase prolactin to the mix.

sunset i dont believe there is a difference. they both mean that you have to stimulate the adrenal gland. when you massage your breasts(mainly the nipple and areola) that actually stimulates the adrenal gland to release prolactin.

SugarQ, I don't think that it necessarily follows that when you have high androgen levels that your oestrogen levels are low. When I was diagnosed with elevated testosterone levels my oestrogen levels were fine despite that fact.
Just thought I would add that, and thanks for all the info, it really helped.

if you have excess testosterone then you shouldnt have an estrogen problem the only problem is the testosterone will over shadow estrogens' effects. theoredically you shouldnt have an low estrogen if you got excess testosterone.
and,sunset, no im not saying if you are low estrogen then dont do the massages. i was just throwing out an idea if you were an excess testosterone lady. prolactin prevents testosterone from being aromatized into estrogen. so massages would prevent the conversion of testosterone into estrogen. so now the only way to do massages for NBE with success is to have an effective anti-androgen to block testosterone. or you can decide not to do the massages, lower prolactin in hopes that aromatization will bump up a little. also increasing cortisol(ive you are deficient) will help also with that.also hi insulin levels cause high testosterone levels. so if you are eating lots of carbs and refined surgars you have a great likely hood of develping insulin resistance in which case your body will pump out more insulin which increases testosterone levels. ive been researching some ways of dealing with excess testosterone but most of the stuff ive come up with dont seem to be safe.lol. i will keep looking,.

I would say chasteberry is not an anti-androgen. It's true that it reduces prolactin levels and that low prolactin allows testosterone to be converted to estrogen. However, it also increases LH (luteinizing hormone) which increases the body's production of testosterone. I believe that this is an established fact, in the male body at least. I don't think the action of chasteberry on testosterone production in the female body has ever been studied. Chasteberry is actually sold as a male supplement to increase testosterone levels for those who feel they are lacking in it. Therefore, if you take chasteberry hoping for an anti-androgen effect, you may find that the outcome is entirely the opposite to what you expected and that androgen levels in the body actually increase. The main function of chasteberry in the female body is to increase progesterone, but it's likely that androgen levels will increase too, although some people dispute this. As I said, the effect of increased LH on testosterone production has only been studied in males, so the position for females is not entirely clear.

First of all thatnks for answering my question. Secondly I found some pretty interesting things about Chasteberry. Read on if interested:
CHASTEBERRY
TRADITIONAL USAGES
Chasteberry has been used since anctient times as a female remedy.
One of it's properties was known to reduce sexual desire,and it is recorded that Roman wives whose husbands were abroad with the legions spread the aromatic leaves on their couches for this purpose. It became known as the chasteberry tree.
During the Middle Ages, Chasteberry's supposed effect on sexual desire led to it becoming a food spice at monasteries, where it was called "Monk's pepper" or "Cloister pepper."
In tradition, it was also known as an important European remedy for controlling and regulating the female reproductive system. Long used to regularize monthy periods and treat amenorrhea and dysmenorrhea, it also helped ease menopausal problems and aided the birth process.
The fruit's peppermint-like odor comes from volatile oils.
RECENT SCIENTIFIC FINDINGS
Chasteberry has not been significantly investigated for its therapeutic effects. However, preliminary investigations do indeed show the presence of compounds which are able to adjust the production of female hormones. It is thought to contain a progesterone-like compound and is now thought to be useful in the following conditions:Amenorrhea,Dysmenorrhea,PMS,Endometriosis.
The chemical constituents are the monoterpens agnuside,eurostoside,and aucubin. Chasteberry also contains the flavonoids casticin,chryso-splenol and vitexin. While it is not known which constituent is responsible for its beneficial effects,it has been shown in laboratory animals in German experiments that extacts of Angus Castus can stimulate the release of Leutenizing hormone (LH) and inhibit the release of Follicle Stimulating Hormone (FSH). An early German study with laboratory animals found that extracts of Chasteberry can stimulate the release of (LH) and inhibit tje release of (FSH). This hormonal effect has been confirmed in another laboratory report which suggests that the volatile oil has a progesterone-like effect.
Employing an aqueous extract from the fruit,Agnolyt, a 1979 study reported good results on premenstrual water retention. Another study of Agnolyt discovered that women were able to sustain a good level of milk production for breast feeding.While it took some time for the drug to take effect, the women were able to continue use of the drug for months without harmful side effects.

Okay, I found an article on Hirsutism that quotes Agnus Castus as being used to treat it, it is at the very bottom!
"Hirsutism can definitely be labeled a hair-raising problem in a woman. And those who suffer from it tend to produce elevated levels of male sex hormones called androgens from their ovaries and adrenal glands. This results in an excessive growth of dark, coarse body and facial hair.
The cause of hirsutism has been identified as being due to medications, which cause excessive hair growth like phenytoin, minoxidil, diazoxixde, cydosporine and hexachlorobenzone. Its cause can also be attributed to HRT, anabolic steroids, birth control pills, danazol and anorexia. Other causes are obesity, severe insulin resistance, tumors on the adrenal glands or ovaries and Cushing Syndrome.
The signs and symptoms which are indicative of hirsutism are hair growth on the abdomen, breasts and upper lip; irregular menstrual period, loss of feminine body shape and formation of masculine traits such as a deep voice, frontal balding, enlarged shoulders and muscles among others.
There is no specific medication for hirsutism though certain medicines may be used for suppression of the production and secretion of androgens in the body. These include: gluco corticoids, spironolactone and certain birth control pills. Other procedures include tumor and ovary removal.
It was discovered that acupuncture helped reduce both hair density and length while significantly reducing the levels of male sex hormones testosterone. Herbalists have recommended herbs such as Black Cohosh (Cimicifuga Racemose), Goats Rue (Galegae Officinalis Herba), Fenugreek (Trigonella foenum-graecum),and Chaste tree (Vitex agnus-castus) to relieve the symptoms."

"Vitex agnus-castus (chastetree berry) has traditionally been used to treat menstrual irregularities and improve fertility. It is thought that vitex normalizes LH (luteinizing hormone). High levels of LH contribute to androgen production.(20) Vitex is an important herb for natural treatment of PCOS."

(no login) Re: Chasteberry an anti androgen? March 2 2006, 6:49 PM
Opinions seem divided, but some definitely regard vitex as increasing testosterone.
See http://www.findarticles.com/p/articles/m..._n13653752
which states "The active components in Vitex agnus-castus are known as agnusides, which lessen prolactin. Although prolactin is thought of as a female hormone, like estrogen, even males have some. While you sleep, prolactin levels rise. High amounts of prolactin can decrease testosterone production. Supplementing with Vitex agnus-castus can ensure that your testosterone levels aren't being blunted."
And see http://www.testosterone2u.co.uk/1185.htm
which states "Vitex agnus-castus increases the natural production of Testosterone."
And finally see http://72.14.207.104/search?q=cache:yuTS...sterone+in+
men&hl=en&ct=clnk&cd=5
which states "Vitex, even though it elevates Testosterone, is included in M due to its ability to reduce prolactin levels a hormone that induces lactation (even in males). So the fact that Vitex actually boosts Testosterone is a nifty secondary effect to M's primary function."

Steph, all this has gotten me really confused as well, so here is another quote and it clearly states at the bottom that it has a "mild" androgenic effect, which kind of makes sense from other links that say that it lowers LH and with this prolactin levels, from which I would conclude what SugarQ explained at the start of the thread.
http://www.organicfood.co.uk/vms/agnuscastus.html
"Agnus Castus
Chaste Tree / Vitex
The basic mechanism of action underlying agnus castus is its effect on enhancing corpus luteal development (thereby correcting a relative progesterone deficiency) via effects through the pituitary gland. Agnus castus has a profound effect on the hypothalamus and on pituitary function, helping normalise other hormones and reducing both prolactin and the estrogen-to-progesterone ratio.
* PREMENSTRUAL SYNDROME - Many PMS sufferers exhibit elevated prolactin levels, especially in women experiencing breast pain or fibrocystic breast disease. Studies in PMS sufferers using agnus castus have shown up to ninety percent having improvement or resolution of symptoms.
* MENSTRUATION DISORDERS - Agnus castus has demonstrated effectiveness in aiding menstruation disorders including; secondary amenorrhoea, metorrhagia, lengthened and shortened cycles, especially when due to progesterone deficiency.
* ANTI-MICROBIAL ACTIVITY - Extracts of agnus castus have shown antimicrobial activity against a broad range of organisms including; staphylococcus aureus, salmonella, E. coli, and candida albicans. This may offer additional benefits, as dysbiosis is a common problem and may aggravate existing menstrual disorders.
* INFERTILITY - Research suggests that agnus castus can enhance corpus luteal functioning, thus lengthening the luteal phase and normalising progesterone levels often found to be low in infertile women.
* INFLUENCE ON LACTATION - Studies have shown favourable effects in aiding milk production (up to three times that of control group), after 20 days of use.
* ACNE - Controlled studies have shown that agnus castus may offer benefit to acne sufferers, most likely due to a mild anti-androgenic effect."
