Xiang Fu, a traditional Chinese herbal medicine, shows significant antidepressant effects.
The study reviewed the major antidepressant mechanisms and clinical applications of Cyperi Rhizoma, known as CR. It aimed to evaluate the pharmacological effects and the chemical compositions associated with these effects. The authors underwent an extensive literature search using "Cyperus rotundus L." as the search term across multiple electronic databases including Web of Science, ScienceDirect, and PubMed.
In discussing the results, the researchers found that CR has broad application in alleviating symptoms related to stagnation of Qi, such as issues with the liver, stomach, and bowels, common in different countries. They identified the effective constituents of CR, including Aqueous extract, EtOH extract, essential oil, total oligomeric flavonoids, and five other extracts. These exhibited various pharmacological activities, such as antibacterial, antioxidant, neuroprotective, antihemolytic, and anti-inflammatory effects. Notably, specific components like α-cyperone and nootkatone showed antidepressant effects. Through synthesizing this scientific information, they concluded that CR holds potential as a herbal medicine to develop antidepressant drugs with fewer side effects.
