No product can target pain in one area of the body like that ie in one part of the musculo/skeletal system, although a healthy diet can be of immeasurable benefit, and some supplements can benefit joints etc
I had a look at one of the links and the jury's out on the benefits ie inconclusive. However I seem to remember this is used as a herb, and many herbs and spices have health benefits - so no harm in adding it to your cooking repertoire, along with a variety of other herbs and spices. After all it is a straight plant product and hasn't been refined or manufactured into a miracle pill! I would try to find a supplier from a grocery type store rather than H & B who will probably sell minute amounts at a price for medicinal purposes rather than as a herb!
The best relief long term for menopause symptoms, is of course HRT if you feel your symptoms becoming bothersome, as this replaces the oestrogen your body is becoming deficient in.
