Please, talk to your Grandson's doctor. Tell him or her what you've posted here and ask if he or she's aware of the association between the intake of Herbalife products and acute hepatitis. If not, suggest he or she have a look at the "Journal of Hepatology" October, 2007. I'd suggest talking to your daughter but, from your post, have the impression she's a "zealot" and you'd be wasting your time.
Understand that I have no way of knowing whether or not the Herbalife products are causing or contributing to your Grandson's problems but I suspect they are and, in my opinion, failure to discontinue them, immediately, is reckless endangerment, at best.
