Holistic for the win!! Sadly I feel the medical system is just that; a system.  A system to keep you sick and keep you coming back as it’s profitable.  I have a family member who had cancer and was encouraged to have milkshakes (liquid sugar) and other sugar filled things. Sadly he lost his battle quickly.  Sugar is the devil.  I believe I’ve also heard great things about black seed oil and CBD oil too. I really hope this can all turn around for your dad! 💜
