BDNF and premenstrual tension: The existing studies on the mechanism of PMS/PMDD have found that the occurrence and development of PMS/PMDD are closely related to the GABAergic system and BDNF, which also provides a potential basis for stigmasterol and kaempferol for the treatment of PMS/PMDD (Sun et al., 2011; Song et al., 2016; Liu et al., 2016), We reasonably speculated that these ingredients might play an important regulatory role in the treatment of PMS/PMDD.
