The efficacy of a composite Indian herbal preparation (CIHP) in sustaining the mental performance of soldiers engaged in prolonged low-intensity-conflict operations has been evaluated. For this purpose, a cohort of 56 soldiers acted as volunteers in combat situations. After recording their initial responses to psychological tests such as the d2 test, the trail-making test, the serial addition test, the short-term memory test, and the Institute for Personality and Ability Testing Anxiety Scale, they were randomly given either CIHP or placebo in a double-blind fashion for 8 days while they performed their usual combat duties. The final 3 days of assignments included physically exhausting and life-threatening events. On day 8, they were withdrawn from combat duties and the psychological tests were readministered immediately. After 7 days of rest, the tests were repeated once again. The results indicate comparatively better performance immediately after the mission by the CIHP group. CIHP was effective at sustaining the mental abilities of soldiers in a low-intensity-conflict environment.
