Edit by Uny: We now offer either Dr. Christopher's version or Dr. Schulzes version...we do NOT supply "cayenne on the side" any longer (as Willowley noted below).
When you order the Eyebright from Uny it is made with an 1/8 part Cayenne, that is the formula Dr. Christopher used. Your bottle should say "1/8 part Cayenne" on the label.
She also sends a 1/2 ounce bottle of Cayenne with it if you want to have the Dr. Schulze one full part of Cayenne. So, if you want the Dr. Schulze formula you would add the small bottle of Cayenne to your bottle of Eyebright and you'd have Dr. Schulze formula with a full part of Cayenne.
