Menopause is one of the natural processes in a female’s life, the most prominent feature of which is the end of fertility and menstruation. Following the psychosocial changes in this period of life, there is considerable evidence that reproductive hormones, especially oestrogen, may influence mood. The aim of this study was to determine the effect of saffron tea on the postmenopausal women’s happiness This study was a randomised controlled trial which enrolled postmenopausal women. Participants (n=72) were randomly assigned to the intervention or control group. The intervention was the use of 30 mg dried stigmas of the saffron plant which was boiled once; one cup of saffron tea was consumed daily with white rock candy. Whereas the control group consumed lukewarm water and white rock candy. Results show that saffron herbal tea significantly increased the mean score of happiness in postmenopausal women, and there was a statistically significant difference between the intervention and control groups. Authors conclude that people should consult with their doctor, and in case he/she approves, use complementary therapies such as saffron herbal teas along with other drugs prescribed by the doctor.
Abstract
BACKGROUND Evidence suggests that menopause can be associated with a variety of negative psychological changes such as depression and anxiety, and improving the mental health status of women during menopause is one of the important priorities and challenges of the health system. The aim of this study was to determine the effect of saffron (Crocus sativus L., Iridaceae) herbal tea on happiness in postmenopausal women. METHODS In this randomized clinical trial which was conducted in 2021, 72 postmenopausal women were enrolled and divided into intervention and control groups. The randomization blocks method was used for random allocation, and the Oxford Happiness Questionnaire was utilized to measure the scores. The intervention included the use of 30 mg of dried stigmas of the saffron plant, which was boiled once (in the morning, in 300 ml of boiling water for 10-15 min) and consumed with white rock candy as one cup of saffron tea daily. To compare the trend of changes and after removing the effect of other variables, generalized estimating equation (GEE) was used. RESULTS There was no significant difference between the intervention and control groups in any of the quantitative and qualitative characteristics (p > 0.05). The results of paired samples t-test showed that the happiness mean score in the intervention group increased significantly (p < 0.001) from 42.93 ± 8.54 to 61.58 ± 8.24, while in the control group, there was no significant difference between the happiness mean score at the beginning and end of the study (p = 0.861). Also, after applying the treatment program in the intervention group, there was a significant difference between the two groups in terms of the happiness mean scores (p < 0.001). CONCLUSION Saffron herbal tea had a positive effect on reducing depression and increasing the happiness score; thus, it is recommended that it should be used as a complementary treatment in consultation with the treating physician. TRIAL REGISTRATION The present study was registered with the code of IRCT20210403050818N1 (Registration date: 09/04/2021) in the Iranian Registry of Clinical Trials. It was also approved by the Ethics Committee of Larestan University of Medical Sciences (Approval ID: IR.LARUMS.REC.1399.017).

Plain language summary
Cardiovascular disease (CVD) is one of the leading causes of death and disability in the world. Atherosclerosis, characterised by the accumulation of fat and inflammation in blood vessels, is the main feature of CVD. Common spices such as pepper, ginger, garlic, onion, cinnamon and chilli may have effects on the initiation and development of atherosclerosis. In this review, the authors focused on the potential protective effects of spices, in atherosclerosis and CVD. Most studies to date have been carried out either in cell culture or in animals. These have revealed various potential mechanisms by which spices exert their beneficial effects, including anti-oxidant, anti-atherogenic, anti-coagulant, anti-inflammatory and cholesterol-lowering properties. There are some human studies evaluating the effects of spices on high blood pressure. Although saffron, turmeric, and chilli pepper had no effect on blood pressure, cinnamon demonstrated significant blood pressure lowering effects in patients with diabetes. Garlic has been shown to have the potential to reduce blood pressure in patients with high blood pressure. These studies provide information on the beneficial roles of spices in reducing cardiovascular risk factors. The types of spices consumed vary across cultures, and currently there are no available population studies showing that consumption of spices is associated with reduction of CVD nor any recommendations for the amounts of spices to be consumed. The authors conclude that the consumption of spices should be encouraged across countries to promote good health.
Abstract
Cardiovascular disease is one of the leading causes of death and disability in the world. Atherosclerosis, characterized by lipid accumulation and chronic inflammation in the vessel wall, is the main feature of cardiovascular disease. Although the amounts of fruits and vegetables present in the diets vary by country, diets, worldwide, contain large amounts of spices; this may have positive or negative effects on the initiation and development of atherosclerosis. In this review, we focused on the potential protective effects of specific nutrients from spices, such as pepper, ginger, garlic, onion, cinnamon and chili, in atherosclerosis and atherosclerotic cardiovascular disease. The mechanisms, epidemiological analysis, and clinical studies focusing on a variety of spices are covered in this review. Based on the integrated information, we aimed to raise specific recommendations for people with different dietary styles for the prevention of atherosclerotic cardiovascular disease through dietary habit adjustments.
