CS is great for the eyes.  I have used it for many years.  Hulda Clark wrote 
that pain in the eyeball itself ALWAYS means that parasites are present in the 
eyeball.  My first dose of her green hull black walnut tincture caused severe 
pain in my left eye to disappear immediately.  The pain returned, but with 
really high amounts of the clove, wormwood and ghbw tincture, the pain has been 
gone for many years now.   The CS eyedrops always helped the pain somewhat.  By 
killing other opportunistic  organisms I assume.  And I still use the CS every 
day several times.  But if  pain es in the eyeball itself then Hulda's parasite 
cleanse with extra oomph is, in my opinion, what is called for.  Hope this 
helps someone.   pj
