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.
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.
Nardostachys chinensis Batalin (Valerianaceae) has been widely used in different traditional systems of medicine, including Islamic, Ayurvedic, Chinese, and Korean folk medicine. It has been used in traditional medicine as a tranquilizer, hepatotonic, cardiotonic, diuretic, and analgesic. Preliminary in vitro and in vivo studies have provided valuable scientific evidence for its traditional uses. This review aims to summarize reported traditional uses, phytochemistry, and pharmacological potential of N. chinensis while identifying potential areas of further research of plant. The review comprises literature pertaining to the pharmacological potential and phytochemistry of N. chinensis using worldwide accepted scientific databases via electronic search (Elsevier, Google Scholar, Pub Med, Scopus, Springer, Wiley online library). Moreover, data from ethno botanical text books available in library and electronic search were also included. The Plant List and Kew Herbarium Catalogue databases were used to authenticate the scientific name. Different pharmacological experiments in many in vitro and in vivo models have proved the potential of N. chinensis, namely, antiinflammatory, anticonvulsant, antibacterial, antihypertensive, antifungal, neuroprotective, cardioprotective, aldose reductase inhibition, and antioxidant activities. The plant contains sesquiterpenenes of various varieties including aristolane, guaiane, and nardosinane types. Moreover, it also contains coumarins, phenols, lignans, neolignans, and glycosides. Reported activities suggested that there may be pharmacological potential for developing N. chinensis as a drug for infections, hypertension, cardiac diseases, Alzheimer's disease, insomnia, epilepsy, cancer, gastric, and liver diseases. More toxicological studies should be performed that will aid the progress to clinical trial studies of N. chinensis.

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.
