What People are Saying...

"I have a condition called "Ulcerative Colitis" based on the inflammation and ulcers in my intestines…Once I started talking to Russell my life completely changed! He had found the missing puzzle pieces to healing Ulcerative Colitis…I am having 1-2 normal bms a day. Weaning off my medications. He gave me home remedies when I became COVID positive and helped me to heal a yeast infection without medication".

I was desperate, so I called Russell and asked for his help. This is the best thing I have done in thirty years. Just after a few weeks, I have relief, real honest relief. No blood, no pain. It almost feels normal!

The day I spoke with Russell was the beginning of the treatment plan that saved my life…I'm having regular, daily, normal, healthy bowel movements. I've lost 10 pounds, my stomach is flattening, my skin is clearing, my energy is rising and so is my mood.
