Dried rhizomes of Cimicifuga racemosa (CR), which are known as black cohosh, have been widely used as herbal dietary supplements to treat menopausal symptoms. The present study examined the effect of CR extracts on human psychological and physiological responses to acute stress induced by mental arithmetic tests, by measuring the subjective stress intensity, the brain-wave patterns according to electroencephalography, and the concentrations of salivary chromogranin-A and cortisol. The experiments were performed double-blind and their order was counterbalanced. Treatment with CR significantly attenuated the elevated subjective perception of stress and the increased salivary chromogranin-A levels compared with placebo treatment. CR extract also rapidly recovered the decrease in alpha waveband induced by performing the mental arithmetic task. We therefore propose that CR extracts might be suitable for the prevention and treatment of stressrelated disorders.

The Ministry of Health, Labor, and Welfare of Japan recommends that an occupational physician (OP) play an important role in implementing the stress-check program since 2015. This study aimed to compare the activities and encountered difficulties of Japanese part-time OPs in 2008 and 2016, and to investigate the effects of the stress-check program. Questionnaires were sent via mail to 946 part-time OPs in Kyoto prefecture in 2016. Completed questionnaires were returned by 181 OPs who were private practitioners or physicians in hospitals, and served as OPs on a part-time basis. In 2016, OPs utilized long hours for activities related to general health examination and to stress-check. Hours for specific health examination, health and hygiene education, health promotion activity, development of a comfortable workplace, and guidance of workers on sick leave reduced from 2008 to 2016. A total of 62% OPs frequently encountered difficulties in the stress-check-related activities in 2016. Many OPs also reported difficulties in the mental health care and the prevention of health hazard due to overwork both in 2008 and 2016. Enforcement of the stress-check program in 2015 changed the activities of part-time OPs in Japan. OPs should be given opportunities to gain more information in this area.
