A chef from north Wales will be exhibiting the world's hottest chilli pepper at the Chelsea Flower Show next week (May 23-27).

The chilli is actually so hot that the vegetable grower had teamed up with Nottingham Trent university to develop it to act as an anaesthetic.

The Dragon's Breath chilli measures an unbelievable 2.48m on the Scoville chart, blasting the Carolina Reaper chilli, formerly known as the world's hottest.

For comparison, the pepper spray used by the US military measures 2m on the same scale, reports the Daily Post .

In fact the chilli is so hot, it has to be kept in a specially sealed container.

Mike Smith, who has been growing vegetables and chillis for the last seven years has already been to the RHS Chelsea Flower, in 2016, but this year he's bringing a chilli so hot it could send you into anaphylactic shock.

Mr Smith, 53, said: "It’s not been tried orally. I’ve tried it on the tip of my tongue and it just burned and burned. I spat it out in about 10 seconds.

“The heat intensity just grows.”

The heat rating means that one drop of the chilli's capsicum oil could be detected in 2.48m drops of water.

By comparison Jalapeño chillis measure somewhere between 3,500 and 10,000 units, while Scotch Bonnet and Habanero chillis measure between 100,000 and 350,000 units.

As well as being an alternative anaesthetic for people allergic to existing anaesthetics, the chilli could be useful in developing countries where access to anaesthetics can be limited due to financial reasons.
