Objectives The date fruit has been shown to possess several health benefits. This study aims to determine the effects of date fruit consumption on the onset and progression of labour. Methods A randomised controlled clinical study was conducted on 89 participants to assess the effects of date fruit consumption on the onset and progression of labour. Twenty-six participants consumed date fruits alone, and 32 consumed date fruits followed by drinking of water. Thirty-one served as controls. Results There was a significant positive impact of consuming (rutab) date fruits on maternal outcomes in both the first and third stages of labour ( p < 0.05 and p < 0.001, respectively). In addition, there was a significant relationship with the foetal well-being factors, such as healthy liquor, foetal heart rate, presence of caput, and A ppearance, P ulse, G rimace, A ctivity, and R espiration (APGAR) score at 5 min ( p < 0.05). The other maternal and foetal well-being factors showed no significant relationship with consumption of date fruits during labour. Conclusion The present study showed a promising effect of (rutab) date fruit consumption on the duration of the stages of labour. No significant differences were observed between the date fruit consumers and their counterparts regarding cervical dilatation; rupture of membranes; strength, frequency, and regularity of uterine contractions; tocometric reports; and maternal progression factors. Additionally, the APGAR score at 5 min was better among the infants whose mothers consumed date fruits.

The methanol extracts of 20 selected medicinal plants were investigated for their effects on the respiratory burst of human whole blood, isolated human polymorphonuclear leukocytes (PMNs) and isolated mice macrophages using a luminol/lucigenin-based chemiluminescence assay. We also tested the effect of the extracts on chemotactic migration of PMNs using the Boyden chamber technique. The extracts of Curcuma domestica L., Phyllanthus amarus Schum & Thonn and C. xanthorrhiza Roxb. were the samples producing the strongest oxidative burst of PMNs with luminol-based chemiluminescence, with IC(50) values ranging from 0.5 to 0.7 μg/ml. For macrophage cells, the extracts which showed strong suppressive activity for luminol-based chemiluminescence were C. xanthorrhiza and Garcinia mangostana L. Among the extracts studied, C. mangga Valton & Vazsjip, Piper nigrum L. and Labisia pumila var. alata showed strong inhibitory activity on lucigenin-amplified oxidative burst of PMNs, with IC(50) values ranging from 0.9 to 1.5 μg/ml. The extracts of Zingiber officinale Rosc., Alpinia galangal (L.) Willd and Averrhoa bilimbi Linn showed strong inhibition on the chemotaxic migration of cells, with IC(50) values comparable to that of ibuprofen (1.5 μg/ml). The results suggest that some of these plants were able to modulate the innate immune response of phagocytes at different steps, emphasizing their potential as a source of new immunomodulatory agents.
