Here is what I can offer... it helped me, and when I am asked, I share it with those who are suffering. It helps them... they have told me that it really does make a difference. When I stay away from all things that are carbs, I am almost hot flash free. Within 20 minutes of consuming ANY carb... a candy, a piece of bread, a bire of rice... I can almost count the minutes, like clockwork... it is hotflash time. When I stay away from the carbs and eat veggies, some fruits( not often and only berries and low carb fruits like cantalope) and lean meats, I am almost hotflash free. Toxin buildup is also a factor... so keep your body away from those things. Weight gain also makes a difference, so try to get your mother on an exercise routine. This helps A LOT. Sauna as much a possible, and get outside in the fresh air and sunlight.

As a long term hot flash sufferer, I can tell you that nothing works except estrogen. Can she get bio identical? I am your mom's age but have been suffering with these since I was in my 20's due to surgery.

They are miserable but low estrogen is better than no estrogen. A time for lots of fats in the diet if she is thin, this helps her store her estrogen for years to come.
If she has an outstanding healthy diet, this is the best thing too but it hasn't slowed my hot flashes down. LOL

Hope she finds a bit of relief but this is one thing there is not clear cut remedy to fix, it's just the body readjusting to the change.

She may try homeopathic remedies;

Boron; for estrogenic balance;
"Another observation I have made is that a nutritional supplement of boron, about 3 mg, one to three tablets daily, also often stops hot flashes"

how long has she been taking Lugol's and how much?
is she salt watering?
vitamin C
b2/3?

if she is still bromide/fluoride toxic her hormone balance might not be able to balance until she has dropped those levels down enough
