I started taking Promensil double strength Red Clover 80mg nearly 3 months ago. At first I genuinely thought it was working. My mood started to improve, my anxiety faded. I've never suffered with hot flashes, so can't report on that.
But I now realise that actually my starting taking them just happened to coincide with my body deciding to produce an 'old fashioned' monthly cycle, like I had a couple of years ago before all this peri-menopause nastiness started. So I enjoyed 4-5 weeks of feeling perfectly 'normal'. Got 'normal' achy boobs. Got 'normal' bloating. Had a 'normal' bleed lasting 6 days (rather than 3). It was (bizarrely) rather nice as recently all my periods have been scant and spotty. Boobs not remotely affected and basically felt rather withered up and dried up.
So I thought I had found the magic elixir. But no, I was wrong. This month I was back to my scant and spotty period. And within 24 hours of it arriving, despite all the Red Clover, my mood took a severe nose dive. Had 12 days of feeling horribly flat and low. Anxiety came back with a vengeance. Endured the worst run of insomnia so far
So, I have to agree with Dana on this. I think if your peri symptoms are very, very slight than phytoestrogens might help. But once your hormones really start to bugger about and dip then some friendly little herbs really aren't going to make a scrap of difference, and certainly not in the tiny concentrations that they're only allowed to be marketed in. But to be honest I think I could have drank a vat of Red Clover extract and it wouldn't have made a difference.
There's hormonal mild anxiety/low mood, where you perhaps worry slightly more than usual and sometimes feel a bit flat. Some herbs and a chamomile tea might help.
Then there's the level of hormonal anxiety/low mood that I experienced where you now completely understand why some people resort to suicide. And for that you need the big guns.
