Hi there
I use it occasionally but not for memory but for mild anxiety. I went through a bad patch after my op last year (although I think most of it was hormone crash) and read about it on another forum. The ones I get also have magnesium, another relaxing herb and B vits so helps all around.
The ashwagandha or Indian Ginseng is an adaptogen so the body will only use what it needs and I don't know if it was pyschosomatic or if it does actually work but it did help! If I get a bit run down on or I can feel the hormones dropping and I get a bit anxious then I take some for a few days and it does seem to help.
So from my point of view it's good stuff!
Hope it helps you! If you are on other meds might be wise to check with the pharmacist or a naturopath first. I consulted one when I started to feel really grotty and there were certain herbs she couldn't give me because of the HRT.
Take care!
