While there’s a variety of sour candies available in the market, not many of them carry a warning label. However, that’s not the case for the British candy Black Death Mega Sours.

It carries a warning on its label, stating that it’s not suitable for anyone younger than 8, and has prompted TikTokers to perform taste tests, resulting in squeals and squirms.

A website selling the candy expands on this, noting “Excessive consumption within a brief time frame may cause temporary mouth and/or stomach irritation.”

There are rumors that sour candy like Black Death can burn the taste buds off your tongue, but in reality, your taste buds are likely not being burned — it just feels that way.

This is because the acid in sour candy (especially in ultra-intense sour candy like Black Death or Warheads) can irritate your mouth and stomach similar to spicy food.

The only real threat these sour candies pose is tooth decay. What happens is the acid from the candy dissolves your enamel, which is what protects you from cavities and decay.
