Cannabidiol (CBD) has been gaining traction in the medical world due to its potential to improve memory and reduce inflammation. A recent study conducted by researchers at UCL has revealed that a single dose of CBD can increase blood flow to the hippocampus, an important area of the brain associated with memory and emotions. The study used a magnetic resonance brain scanning technique, spinal arterial labeling, to measure changes in oxygen levels. The results showed that CBD significantly increased blood flow in the hippocampus and orbitofrontal cortex.
The orbitofrontal cortex is involved in decision-making, while the hippocampus is responsible for memory. This suggests that CBD may improve memory function by increasing cerebral blood flow. In addition, CBD has been found to protect against vascular damage caused by high glucose levels, inflammation, and type 2 diabetes in animal models. It also reduces vascular hyperpermeability associated with these conditions.
In the heart, CBD treatment protects against ischemia and reperfusion damage and cardiomyopathy associated with diabetes. In vivo, CBD does not appear to have any effect on blood pressure or resting heart rate, but it does reduce the cardiovascular response to various types of stress. It also causes time-dependent vasorelaxation in the rat aorta at concentrations greater than 100 nM. CBD also changes the way the brain processes emotional memories, which could explain its reputed therapeutic effects on PTSD and other psychiatric disorders.
It is thought to act on PPARgamma receptors to reduce inflammatory markers. CBD is a natural substance used in products such as oils, edibles, and lotions to provide a sense of relaxation and calm. With guidance from a doctor and favorable lifestyle changes, CBD may help reduce intraocular pressure.
