The purpose of this study was to evaluate the effects of Matricaria recutita extract (the active ingredient in chamomile tea) on sleep quality, fatigue, and depression in postpartum women. Sleep quality is a significant issue for women after childbirth and chamomile is widely used as a folk remedy for its presumed sedative-hypnotic effects. A total of 80 Taiwanese postnatal women, aged 25-35 with poor sleep quality were recruited from November 2012-August 2013. They were randomly assigned to one of two possible groups of 40 people each. The participants in Group 1 were instructed to drink M. recutita extract (540mg/day)) daily for a period of 2 weeks. The participants in Group 2 received regular postpartum care only. The Postpartum Sleep Quality Scale (PSQS), Edinburgh Postnatal Depression Scale, and Postpartum Fatigue Scale were used to assess sleep quality, fatigue, and depression with higher scores indicating poorer outcomes. Compared with Group 2, Group 1 demonstrated significantly lower scores of physical-symptoms-related sleep inefficiency (t = -2·482, P = 0·015) and the symptoms of depression (t = -2·372, P = 0·020). Chamomile tea may be recommended to postpartum women as a supplementary approach to alleviating depression and sleep quality problems.

"A new asset is available for $236,000. O&M costs are $10,000 each year for the first five years, $13,300 in year six, $19,300 in year seven, and $28,800 in year eight. Salvage values are estimated to be $144,000 after one year and will decrease at the rate of 49% per year thereafter. At a MARR of 10%, determine the economic service life of the asset. Enter your answer as an integer from 1 to 8."
