Iodine is purple to black.
The two orange antiseptic coatings would be Mercurochrome & Merthiolate
Root Beer is mostly Sarsaparilla, with some hint of Sassafrass, Vanilla and a few others. I would have to check my recipes.
Also, from those times is Birch Beer, Spruce Beer, Horehound Candy (mkaes very good cough drops, BTW) and some others.
Somebdoy recently mentioned the old Neeco Candy from those old days. I liked those,some didn't.
We used to get Sassafrass Candy sticks and Horehound Candy sticks. The Horehound was in a spiral twist. The Sassafrass sticks were plain cylinders that looked like barber poles from the colored coatings.
I recently found some Sassfrass Candy that was supposed to be the same as the "old time" version. But it wasn't: in the reverse of what E-Man said, this tasted like they had ADDED disinfectant.
