A new case study reveals medical marijuana may provide rapid relief for sufferers of chronic itch. Researchers say THC attaches itself to brain receptors that influence the nervous system. This reduces inflammation and nervous system activity, leading to a reduction in itch sensation.
Researchers identified a set of neurons in the spinal cord that transmits a light-touch signal from the skin to the brain. NPY-Y1 signaling regulates the transmission of innocuous tactile information by establishing thresholds for touch discrimination and mechanical itch reflexes. The findings shed new light on the neurobiological basis of chronic itching.
People suffering from chronic itching as a result of a condition called chronic idiopathic pruritus found some symptom relief after taking a drug designed to treat rheumatoid arthritis, researchers report.
