If I were in this same predicament, I would be using the 3 parts mullein to 1 part lobelia (I assume this is what you mean by the glandular formula) - make into a strong tea (decoction), dip a cotton cloth in it and wrap it around the throat and lower jaw line, keeping it moist and warm - at least two or three times per day for an hour. I would also be drinking the tea, along with using a good thyroid formula (with Kelp) orally. I would also be on a juice/wheatgrass fast to alkalize the body. At the very least, I would be on a completely vegan diet, using lots of live fruits and vegetables with alot of fresh juicing.
Now, having said that - even if you do these things - if she continues to smoke or eat meat - it is like driving down the road with one foot on the brake and one foot on the gas - you are not going to get any where!! If you truly want to be able to heal yourself, you must be willing to make the life-style changes necessary to cleanse your body and bring it back into balance or you are wasting your time. You might as well turn your health over to the medical world and hope for the best.
I know this sounds hard and cruel, but I've seen it too many times. Just this past year, I watched one of the sweetest men you will ever meet take on a battle with cancer. He did a 40 day juice fast - used all of the alternative modalities he could possibly use and was not able to stop the progress of the cancer. Why? Because he had used chemotherapy 5 years ago and he could not give up his morphine due to the intense pain he was in. Because of the damage from the previous chemo and the intense acidity (among other things) of the morphine - nothing he did could overcome those two things. The bottom line is - YOU CAN'T WALK THE FENCE - you have to choose one way or the other. If you don't, you're only kidding yourself. Nature is no respecter of persons - she will follow the natural laws and you will suffer the natural consequences.
