[roberta1963]

Nevermind. I just saw that Roberta recommended Siriporn in another thread. I hope she's right.... Looked itup and realized that Siriporn is that brand with the horrible looking website that used to always advertise around here. Or at least it appeared that that's what they were doing. That doesn't necessarily mean that their product is bad, but it raises some red flags. I wonder if anyone else can verify the claim that American brands can't standardize for miroestrol. I don't see why that would be the case, but I have literally know idea how herbs are standardized.

Stephie you did not read what I wrote....the most important thing to measure the actives is to have the marker compounds like miroestrol.
There are only a few people in the whole world that have it.   They do research at several Universities.   The only people that I'm
aware of that where able to synthesize it is E.J. COREY a nobel prize winner in chemistry at Harvard and his graduate student Larry WU
in about 1990. They did iy in 18 steps. A pharmaceutical cmpany will not make a drug typically if it goes beyond 5 steps.
Its not easy to isolate from the plant.   Its not the kind of thing a supplement company is not set up to do.  Its as simple as
that.  They can measure it now in Japan and several of the universities in Thailand because several professors were able to isolate it from the plant.
There is no magic its not easy work.  You can look for Dr. Corey's paper online if he is living he is probably in his 90's.
