In a recent study, CBD has shown that it can be affective against gram negative bacteria.

Gram negative bacteria have an extra outer membrane or defense that makes them resistant to traditional antibiotics.

The range of gram negative bacteria CBD was found to destroy was gonorrhea, otherwise known as "the clap."

The researchers also went a step further to study how fast the bacteria could mutate to try and outwit CBD and its killing power. It was found that CBD causes a low tendency to show resistance in bacteria!
