Research Roundup: Jan 28, 2025



Best of cannabinoid science this week...


For chronic pain & PEA, a meta-analysis including eighteen studies & ~1200 patients found that PEA reduced pain and & enhanced quality of life

In a case report someone with both Lennox–Gastaut Syndrome (the severe childhood epilepsy) & Alpha-1,3-Mannosyltransferase-Congenital Disorder of Glycosylation (ALG3-CDG: a rare genetic disorder of early neurological abnormalities, abnormal facial features & eye problems), CBD & changes to diet led to seizure freedoms for over 13 months, significant improvements to EEG scans and percent enhanced developmental outcomes

First case report of effective and safe application of cannabidiol to treat concurrent ALG3-CDG and Lennox–Gastaut Syndrome


In horses, there were no adverse effects from CBD or CBDA (1 mg/kg)

For beta-caryophyllene (one of the most common terpenes in cannabis), a review of its wide-ranging effects & its ability to activate the CB2 receptor

A Systemic Review of Beta-Caryophyllene


In a mouse model of pain from colitis, CBD, CBG, CBC & CBDV all reduced visceral hypersensitive pain

Entourage effects of non-psychotropic cannabinoids (npCBs) on visceral sensitivity in experimental colitis

 

In a mouse model of kidney damage from chemotherapy treatment, cannabis extract improved urinary parameters, restored migratory capacity & prevented apoptosis (programmed cellular suicide)
