Washington, Feb 4: Zen meditation - a centuries-old practice that helps people gain mental, physical and emotional balance - can keep pain at bay, according to Universite de Montreal researchers.

According to a Psychosomatic Medicine study, Zen meditators have lower pain sensitivity both in and out of a meditative state compared to non-meditators.

Washington, November 24: New and highly effective treatments for chronic pain may soon be available, thanks to researchers at the Scripps Research Institute who have identified a compound which can inhibit one of the enzymes that break down the pain-killing effect of marijuana.

Marijuana kills pain by activating a set of proteins known as cannabinoid receptors, which can also regulate appetite, inflammation, and memory.
