I dont think it's a good idea to be suggesting treatments like a liver cleanse to people. Not everyone needs to do that, plus you dont know if that wouldnt cause her more of a problem.

What she needs to do is go to a doctor and have bloodwork and/or a physical to see if she's deficient in something, or if she's anemic. She could be having an exacerbation and that could be what's causing her problems.

The only people who should be suggesting treatments are doctor's who have the necessary training and equipment needed for diagnosing conditions. (sorry...took a medical ethics course for my medical transcription classes and am taking what I learned pretty seriously, I dont even suggest Tylenol to other people who have headaches anymore)
