A bath with Pascalite clay (www.relfe.com) is a very safe and direct direct way to remove noxious chemicals and metals from the body. While in the bathtub, if possible, apply some wetted clay to her whole head and make a facemask with it. One pound per bath is sufficient. Have her soak in the water for about half an hour. Let the bathwater stand for a few hours and then drain off the water, but keep the settled clay in the bathtub. Check for black sediments in the clay (metals). Remove the clay.
You may repeat this one more time after about two months.
