Quoted from RTS:I was actually serious.
I really think Tums and Necco are the same thing. Tums taste more like chalky candy than medicine and I suspect Necco works like an antacid too.
If you try it, you'll know what I mean.
I played a NECCO making pharmacist on an episode of a tv show titled "Underground", I was also the prop master for the show for it's two seasons.
NECCO was amazing with their support and sent me their recipe as well as ingredients to make several authentic batches. I can tell you it's not Tums.
My role was cut down on the edit, but I am still the first 45 seconds.
NECCO is a cool American company in my opinion, and yes they do make the candy hearts. A lot of memories for a lot of folks with just those two products.
