Cleome scaposa has been associated with the prevention of many diseases as fever, abdominal complaints and cancer. But its antipyretic effect is not reported so far. The aim of this study was to assess the efficacy of C. scaposa in reducing temperature in Baker's yeast-induced fever model of rabbits. Rabbits were randomized into 4 groups (n = 24). Fever was induced in by Saccharomyces cerevisae (3 mL/kg of 10% suspension subcutaneous) in all study groups. Afterward, group 1, 2, 3 and 4 were orally administered with paracetamol 150 mg/kg b. wt., distilled water, C. scaposa 250 and 500 mg/kg b. wt. respectively. 500 mg/kg dosage was selected after dose fixation study. The standard control was paracetamol. Rectal temperature was recorded with the help of a digital thermometer. ANOVA followed by post hoc test was applied for statistical analysis of results. Results of the study indicate that C. scaposa possesses antipyretic activity comparable to that of standard drug paracetamol as it exhibited comparable antipyretic potential against baker's yeast-induced fever in rabbits. This study confirms the traditional use of C. scaposa in fever. So, it can be an alternative therapeutic choice in fever. However, specific constituents responsible for its antipyretic activity should be evaluated.

Objectives Cassia absus is a plant of the family fabaceae with Ayurvedic ethnomedical records. It is used in traditional medicine for the treatment of bronchitis, asthma, cough, conjunctivitis, leucoderma, renal and hepatic diseases, constipation, tumors, venereal ulcer, headache, hemorrhoids and wound healing. Preliminary in vitro and in vivo studies have provided valuable scientific evidence for its use. This review aims to summarize reported pharmacognosy, traditional uses, phytochemistry and pharmacological potential of C. absus while identifying potential areas of further research of plant. Key findings The review comprises literature pertaining to the evidence base therapeutic potential, pharmacognosy and phytochemistry of C. absus spanning from 1935 to 2016 using published articles in peer-reviewed journals, ethno botanical text books, and worldwide accepted scientific databases via electronic search (Elsevier, Google Scholar, PubMed, Scopus, Springer, Web of Science, Wiley online library). Kew Botanical Garden databases and the Plant List were used to authenticate the scientific names. Different pharmacological experiments in many in-vitro and in-vivo models have proved the potential of C. absus with antihypertensive, antifertility, antifungal, anti-inflammatory, anti-hyperglycemic, anti-glycation, antibacterial activity, a-amylase inhibitory activity, antioxidant and reducing activitity etc. chaksine, iso-chaksine, saturated and unsaturated fatty acids, chrysophanol, aloe-emodin and a wide range of chemical compounds have also been reported. Toxicity studies reveal the nontoxic nature of C. absus at a dose of 2000 mg/kg, however, plant possess reproductive toxicity and can be used as birth control or abortifacient. Summary Reported activities suggest that there is sufficient pharmacological potential for developing C. absus as a drug for hypertension, infections, diabetes and its complications. However, heterogeneity in study protocol and conflicting results mask the ability to replicate these studies. So, future studies should be replicated in line with best practices. More toxicological studies would aid the progress to clinical trial studies. Various ethno medical uses of C. absus have not been evaluated yet.

Background Belladonna and Pyrogenium are commonly used to treat fever in homeopathy. But in vivo antipyretic activity of these medicines is not reported yet. The study was conducted to evaluate the effectiveness of ultrahigh dilutions of Belladonna (Bell) and Pyrogenium (Pyro) in fever model of rabbits induced by Baker's yeast. Methods Healthy, local strain rabbits (♂ and ♀) were divided into seven groups (n=42): Normal control, negative control, standard control, pyro 1000c, pyro 200c, Bell 1000c and Bell 200c. Fever was induced by intra peritoneal injection of 135 mg/kg Baker’s yeast suspension. Rectal temperature was measured hourly. All the medicines were administered once a day. The results were expressed as mean ± SEM. ANOVA and least significant difference post hoc test were applied for checking the level of significance, p-value of ≤0.05 was considered significant statistically. Results Pyro in both potencies significantly reduced fever in rabbits compared to negative control group, while both potencies of Bell were ineffective. Paracetamol and Pyro 1000c reduced by 1.2 °C (39.7 ± 0.1 to 38.5 ± 0.1), while Pyro 200c reduced by 1 °C temperature (39.7 ± 0.5 to 38.7 ± 0.2). Conclusions Pyro possesses marked antipyretic activity in rabbit’s Baker's yeast fever model. It would embolden its clinical use in fever with more guarantee of its efficacy. However, caveat of small sample size necessitates replication of experiment in large sample size.

Hyperuricemia is a metabolic disorder with characteristic elevated serum uric acid. Recently, several plant-based medicines are being used for the treatment of hyperuricemia. The study aimed to find the hypouricemic potential of Berberis vulgaris in in-vitro and in-vivo study models. In i n-vitro studies, xanthine oxidase inhibition assay was performed to evaluate IC50 value and capsule absorbance of the drug, respectively. For in-vivo experiment, the study comprised 15 groups of rats. In-vitro results revealed that significant xanthine oxidase inhibition was shown by Berberis vulgaris with an IC50 value of 272.73±.3 μg/mL. Similarly, oral administration of Berberis vulgaris with dosages of 250 and 500 mg/kg decreased serum and liver uric acid levels significantly in a dose- and time-dependent manner in oxonate-induced hyperuricemic rats. Furthermore, 3-day and 7-day administration of Berberis vulgaris showed more potential compared to 1-day administrations. The present study indicated marked hypouricemic effects of Berberis vulgaris in rats. Due to caveat of the small sample size, a firm assumption of the hypouricemic effect of Berberis vulgaris cannot be made. However, extensive study is needed to find out the exact molecular mechanism involved and to translate its effects into clinical trials for the further validation of the results.

BackgroundHomeopathy is a controversial alternative system of medicine. The action of homeopathic medicines is considered slow and it is assumed that homeopathic medicines are ineffective in acute conditions such as fever.ObjectiveIn the present study, effects of 3 homeopathic medicines on baker's yeast induced fever were investigated.Materials and methods42 local strain rabbits were equally divided into 7 groups. Normal saline was orally administered to group 1 (normal control) rabbits without fever induction. Group 2 underwent baker's yeast-induced fever (negative control). Groups 3, 4, 5, 6 and 7 underwent baker's yeast-induced fever and were thereafter treated orally with paracetamol, Nux vomica 200C and 1M, Calcarea phos 200C and Belladonna 200C respectively. Rectal temperature was checked hourly. The abdominal writhing and frequency of loose stools were also monitored. ANOVA was applied for checking statistical significance. p ≤ 0.05 was considered significant.ResultsThe rectal temperature increased significantly (p < 0.05) in the negative control group when compared to the normal control. Abdominal writhing and loose stools monitoring showed increased writhing and loose stools frequency of group 2, 3, 6 and 7 rabbits. However, treatment of paracetamol significantly reduced rectal temperature. Group 4 & 5 showed significant reduction of rectal temperature together with abatement of abdominal writhing and loose stools.ConclusionN. vomica ultra-high dilutions have normalized rectal temperature and prevented the abdominal writhing and loose stools in baker's yeast-induced fever model of rabbits. It could be due to antidotal activity of N. vomica ultra-high dilutions. Therefore, N. vomica ultra-high dilutions can be useful antipyretic agents and can treat conditions associated with gastrointestinal symptoms. However, fixed conclusion can't be asserted due to caveat of small sample size.
