"We no longer sell it without Cayenne - as of today, we mix it all to Dr. Christopher's formula and include a little bit of Cayenne 'on the side' (if added to the bottle, would turn it into Dr. Schulzes formula/ratio)."
What you've got in the Eyebright bottle is Christopher's formula (not as hot) so I can hardly wait until you try it to see if the BURN is there for you lol. If not then you can add the extra Cayenne she sent with it but I'd sure try Christopher's first if I were you.
I'll be sittin on pins and needles until I hear back from you. Go for it Telly!
