Study: CBD Reduces Arsenic-Induced Kidney Damage

The Marijuana Herald - Marijuana news and information

Researchers from Ahvaz Jundishapur University of Medical Sciences in Iran have discovered that cannabidiol (CBD) can significantly reduce kidney damage caused by arsenic exposure in mice.

Published in the peer-reviewed journal Research in Pharmaceutical Sciences , the study explored how CBD influences specific pathways involved in oxidative stress, inflammation, and cell death, particularly the NOX4 and NF-kB pathways.

The study involved 48 male mice divided into six groups. Some groups received only arsenic, while others were treated with varying doses of CBD prior to arsenic exposure. The researchers measured several markers of kidney health, oxidative stress, inflammation, and apoptosis, as well as performed histological analyses on kidney tissue.

Results found that arsenic exposure led to severe kidney damage, characterized by increased oxidative stress, inflammation, and apoptosis. However, pretreatment with CBD was able to reverse many of these harmful effects. CBD decreased the levels of key pro-inflammatory markers and oxidative stress factors, such as NOX4 and NF-kB, while boosting antioxidant levels.

The findings suggest that CBD’s protective effects against arsenic-induced nephrotoxicity are due to its ability to modulate oxidative stress, inflammation, and apoptosis through the NOX4 and NF-kB pathways. This research highlights the potential therapeutic use of CBD in treating kidney damage caused by toxic substances like arsenic.
