The study looked at how the leaves of the sweet flag plant affect animals' behavior, anxiety, depression, muscle tone, and movement coordination. The researchers made an extract from the plant and tested it on mice. They found that the extract had a dose-dependent effect on the animals' activity levels, muscle tone, and coordination. At certain doses, the extract showed some protective and stimulating effects. This suggests that the sweet flag plant extract could potentially be used to create drugs for treating disorders of the central nervous system.
