Hi Mamarabbit. Sorry for the delay, I saw your post below but have been pretty sick, but... now on my way back to recovery. I found a few things out re: my hotflashes coming back, but first let me tell you what I was taking that got completely rid of the hot flashes for nearly three months. I am starting the series over again. I was disappointed when they returned, but I think I have a grasp on why they returned, so even though I would have taken them again anyway, I am almost excited to start again to test out what I learned. I don't know about cold flashes, but I get cold really easily also as I am really thin - no insulation. I was taking (tinctures) of **** Quai, Chaste Tree, Licorice root and Wild Yam. One thing that helped me besides taking these herbs was kidney, gall bladder, liver and colon cleanse. While I was home on sick leave I also swollowed at least three cloves of garlic and drops from tinctures of Cheyenne every day to cleanse my blood.
I also took tincture drops of a mixture of: ****-quai, Angelica polymorpha sinensis root, Chaste Tree, Vitex agnus-castus berry, Wild Yam, Dioscorea villosa root, Valerian root, Valeriana officinalis, Lobelia pod and seed, Lobelia inflata, Passion flower, Passiflora incarnata, Hops flower, Humulus lupulus, Uva Ursi leaf, Arctostaphylos uva ursi, Juniper berries, Juniperus communis and Corn Silk, Zea mays.
I bought those from a very strong willed well known herbal "doctor". He is know as the herbdoc on the internet... without giving websites, I am sure you can figure the site address out from there.
