Various tests of psychomotor performance were carried out in a group of 16 healthy male volunteers given a standardized preparation of Korean ginseng (G 115; 100 mg twice a day for 12 weeks) and in a similar group given identical placebo capsules under double-blind conditions. A favourable effect of G 115 relative to baseline performance was observed in attention (cancellation test), processing (mental arithmetic, logical deduction), integrated sensory-motor function (choice reaction time) and auditory reaction time. However, end performance of the G 115 group was superior statistically to the placebo group only in mental arithmetic. No difference between G 115 and placebo was found in tests of pure motor function (tapping test), recognition (digit symbol substitution) and visual reaction time. No adverse effects were reported. It is concluded that G 115 may be superior to placebo in improving certain psychomotor functions in healthy subjects.
对一组16名健康男性志愿者进行了各种心理运动表现测试。这些志愿者被给予标准化的高丽参制剂（G 115；每天两次，每次100毫克，共12周），另一组相似的志愿者在双盲条件下服用相同的安慰剂胶囊。在注意力（划消试验）、处理能力（心算、逻辑推理）、综合感觉运动功能（选择反应时间）和听觉反应时间方面，观察到G 115相对于基线表现有积极效果。然而，G 115组的最终表现仅在心算方面在统计学上优于安慰剂组。在纯运动功能测试（敲击试验）、识别（数字符号替换）和视觉反应时间方面，未发现G 115与安慰剂之间存在差异。未报告不良反应。结论是，G 115在改善健康受试者的某些心理运动功能方面可能优于安慰剂。
