The study
The participants were assigned to rub their knee with a fingertip amount of either Atlas pistachio oil (derived from Pistacia atlantica trees in Iran; a relative of the common pistachio) or diclofenac gel (the control) 3 times daily.
Osteoarthritis symptoms improved in both groups, but pain improved more in the Atlas pistachio group, according to scores on a Visual Analog Scale and the Knee Injury and Osteoarthritis Outcome Score.
