I did the guai protocol for 10 years. It's a fairly harmless & cheap medication. It was cheaper as a prescription drug though. I always bought mine on ebay & got it for half what Walmart charged. I started high levels of vitamin D3 the beginning of this year & no longer require guai.

It makes sense, the body doesn't have a guai deficiency. Guai never made me better, it just managed symptoms. What I didn't like about it is that taking almost any herbs or supplements with it would block it from working. I couldn't take spirulina when I was on it & feared trying most anything.

My theory is that lymph fluids get thick & pool around nerves putting pressure on them causing pain. Guai as well as vit.D3 thin out the lymph fluids.
