What happened to sulfur and cream of tartar tablets?

Question

I live in the deep south and when I was a kid my dad used to give me sulfur and cream of tartar tablets\lozenges to repel ticks. They used to work so well, I started looking for them and they appear to have gone the way of the dodo. Does anyone know why? I appreciate it.

Answer 1

I don't know what happened but my dad always chewed off the tip of matchsticks...the sulfur tip... to repel mosquitos etc.
