to the selfless caregiver trying to save her mother in law: (previous bread)
please try near infrared sauna (red light/heat therapy).
It WORKS.
go to saunaspace.com, it is low EMF. Hope you see this.
Also, for immune system boosting try medicinal mushrooms (Reishi, Maitake, Turkey Tail)
they will help her fight infections. Doctors will NOT tell you this, but I know from experience.
Saved my mother's life.
