Charlotte's seizures were dramatically reduced...

CBD oil , or cannabidiol oil, is derived from the hemp plant and is known to have a wide range of potential therapeutic benefits. One area where CBD oil has shown promise is in reducing seizure activity, particularly in people with certain types of epilepsy.

The specific mechanisms by which CBD oil reduces seizure activity are not yet fully understood, but it is thought to involve several different processes in the brain. One possible way that CBD oil reduces seizures is by interacting with receptors in the brain that are involved in regulating electrical activity. These receptors, known as CB1 and CB2 receptors, are part of the endocannabinoid system, which plays a role in a variety of physiological processes.

CBD oil may also help to reduce seizure activity by modulating the release of certain neurotransmitters in the brain. For example, it has been shown to increase the levels of the inhibitory neurotransmitter GABA, which helps to reduce excessive electrical activity in the brain.

Charlotte's Web is a specific type of CBD oil that is known for its high concentration of CBD and low concentration of THC (the psychoactive compound in cannabis). It was originally developed for a young girl named Charlotte Figi who suffered from a rare form of epilepsy known as Dravet syndrome. Charlotte's seizures were dramatically reduced after she started taking CBD oil, leading to widespread interest in the potential therapeutic benefits of this compound.

Overall, while the precise mechanisms by which CBD oil reduces seizure activity are not yet fully understood, there is growing evidence that it may be a useful treatment for certain types of epilepsy. 

However, it is important to note that CBD oil should only be used under the guidance of a healthcare professional, as it can interact with other medications and may have side effects in some people.
