After giving Rhizoma Gastrodiae to aging rats continuously for 3 months, the process of their learning and memory was observed through step-down test and the content of lipid peroxides (LPO) was determined. It has been found out that Rhizoma Gastrodiae can effectively improve the ability of learning and memmory of these rats and reduce the content of LPO. The result may indicate that it is by clearing away the free-radicals that Rhizoma Gastrodiae improves the brain function.
连续3个月给老龄大鼠灌胃天麻后，通过跳台试验观察其学习记忆过程，并测定脂质过氧化物（LPO）含量。结果发现，天麻可有效提高老龄大鼠的学习记忆能力，并降低LPO含量。这一结果提示，天麻可能是通过清除自由基来改善脑功能的。
