Human Milk Endocannabinoid Levels as a Function of Obesity and Diurnal Rhythm

In a patient with severe pain after a stroke, a 1:1 ratio of THC & CBD gave relief after 3 years of other therapies did not

Tetrahydrocannabinol and cannabidiol as an oromucosal spray in a 1:1 ratio: a therapeutic option for patients with central post-stroke pain syndrome?

Preclinical Research & Cannabinoid Chemistry

In rats exposed to UV radiation, topical CBD protected the skin & also absorbed into the bloodstream where it proceeded to the liver & caused many changes

Changes in Hepatic Phospholipid Metabolism in Rats under UV Irradiation and Topically Treated with Cannabidiol

In baby rats with crushed spinal cords, CBD protected the neurons in the spine & reduced the reaction of the glial cells, probably via the CB1 receptor

Short and long-term neuroprotective effects of cannabidiol after neonatal peripheral nerve axotomy

In a rat model of seizures, both THC & CBD are effective at have antiseizure properties but the most effective is a small amount of THC added to a larger dose of CBD

Antiseizure effects of the cannabinoids in the amygdala-kindling model

In mice addicted to cocaine, CBD helped to prevent drug motivated behavior

Cannabidiol produces distinct U-shaped dose-response effects on cocaine conditioned place preference and associated recruitment of prelimbic neurons in male rats

In glioma cells (the fastest growing type of brain tumor), CBD caused the transcription factor NFKB to become toxic to the tumor cells

OMRT-1. Cannabidiol converts NFKB into a tumor-suppressor in glioblastoma with defined antioxidative properties

In placental cells, CBD affects apoptotic and autophagic processes

Cannabidiol disrupts apoptosis, autophagy and invasion processes of placental trophoblasts

In a mouse model of Alzheimer’s, inhibiting the FAAH enzyme (a mechanism of CBD) lowers inflammation of the microglia (brain immune cells) via several different cellular processes

Fatty Acid Amide Hydrolase (FAAH) Inhibition Modulates Amyloid-Beta-Induced Microglia Polarization

In neurons of the hippocampus, activating the CB2 receptor protected them from the Aβ plaques associated with Alzheimer’s

CBD also targets the PPARs & in some studies, CBD has been found to turn on hundreds of different genes & turn off hundreds of other genes.

No wonder it’s often so hard to figure out exactly how CBD is helping.
