Are humphreys teething pellets good?

My mom used them on me and my brother when we we're babies. But I have heard mix reviews about it saying they are great and have worked fast after taking them but I've also read that they are bad and unsafe, 1 review on amazon said it caused a 8 month old seizures. So I really don't know what to do.

      I could not find humphreys. I had to buy hylands. I hope they help a little.
