In Vivo Efficacy, Toxicity Assessment, and Elemental Analysis of Traditionally Used Polyherbal Recipe for Diarrhea.

A polyherbal formulation consisting of Mentha piperita L., Camellia sinensis L. Kuntze, and Elettaria cardamomum (L.) Maton with a ratio of 10 : 5 : 2, respectively, was recommended for curing nausea, vomiting, and diarrhea. Experimental validation is crucial to affirm its therapeutic property leads toward the development of modified antidiarrheal agents. This research aimed to investigate the in vivo antidiarrheal efficacy of traditionally used polyherbal recipe in a castor oil-induced animal model. Moreover, the study also presents the elemental screening and in vivo toxicity of tested polyherbal recipe. Individual plant parts of the polyherbal recipe were mixed according to the traditional prescription ratio, and hydromethanolic extract was prepared by the cold maceration process. The antidiarrheal activity was assessed by castor oil induction method, charcoal meal test, and enteropooling procedure in Sprague-Dawley rats. Elemental analysis and in vivo subacute toxicity were carried out, followed by biochemical, hematological, and histopathological analyses. Polyherbal extract significantly delayed the diarrhea onset in a dose-dependent manner and showed marked inhibition at 200 and 400 mg/kg. Fecal weight was reduced significantly (p < 0.05) at 200 mg/kg (0.26 ± 0.25) in comparison with the control (1.63 ± 0.15). The diarrhea score was zero at a concentration of 200 and 400 mg/kg. Antienteropooling effect of the extract was greater than that of loperamide. Following subacute toxicity, all the treated rats were normal, survived, and showed no changes in behavior. There were no significant differences between values of blood parameters in both the control and extract-treated groups except a significant decrease in monocytes (control 8.4; polyherbal 2.2). Elemental analysis showed a slight increase in the amount of manganese (Mn, 8.076 ppm) as compared to the WHO recommended level (2 ppm). Traditionally used polyherbal recipe is effective and safe for combating diarrheal diseases. In vivo evidence supported the use, safety, and efficacy of the polyherbal recipe that has been used as an alternative medicine for diarrhea in the study area. Inhibition of castor oil-induced diarrhea and antisecretory effect of the studied polyherbal recipe makes it a potent antidiarrheal drug without no or limited toxic effects at the tested dose after further analysis.

Ethnogynaecological assessment of medicinal plants in Pashtun's tribal society.

The present study was designed to document detailed ethnogynaecological knowledge of selected remote regions of Pashtun's tribe in northwest Pakistan. Semistructured questionnaires were designed to collect ethnogynaecological and ethnographic data. Total of 51 medicinal plants belonging to 36 families were documented that were used by the women of studied regions for the treatment of 9 types of gynaecological complaints. Majority of the plants (19) were found used against menses followed by 11 plants each for gonorrhea and pregnancy. Bannu region has high number of gynaecological plants (22) followed by Karak (15). Women of the regions mostly used whole plants (33%) and leaves (31%) for various ethnomedicinal preparation of gynae. Fic results showed that all ailments in different areas scored high consensus ranges between 0.6 and 1.00. Majority of the female respondents (44%) were aged between 61 and 70 years, of which most were illiterate. Women in the remote regions of Pakistan have tremendous traditional knowledge in utilizing medicinal plants for their reproductive health. Plants with high Fic values should be cross-checked for their in vitro and in vivo validation. Young girls should be educated on the importance of ethnogynaecological practices to conserve this valuable knowledge.

Ethnopharmacological assessment of medicinal plants used against livestock infections by the people living around Indus River.

The present study was aimed to document detailed ethnopharmacological knowledge of medicinal plants against livestock infections of an unexplored remote region of Pakistan. Semistructured questionnaires were used for data collection. Total 43 plants belonging to 26 families were found to be used in ethnoveterinary practices. Seeds (29%) were found to be the most frequent plant part used followed by leaves (22%). Ethnoveterinary recipes were mostly prepared in the form of decoction and powdering. Informant consensus factor (Fic) results revealed high consensus for gastrointestinal (0.81), mastitis (0.82), and dermatological infections (0.80). Curcuma longa ranked first with highest fidelity level (FL) value (66%) followed by Trachyspermum ammi that ranked second (58%). Preference ranking (PR) results showed that Zingiber officinale, Punica granatum, Triticum aestivum, Gossypium hirsutum, and Withania coagulans were the most preferred species for the treatment of diarrhea. Direct matrix ranking (DMR) results showed that Morus alba, Melia azedarach, Withania coagulans, Cassia fistula, Azadirachta indica, and Tamarix aphylla were the multipurpose species of the region. We invite the attention of pharmacologists and chemists for further exploration of plants having high Fic, FL, and PR values in the present study. Conservation strategies should be adopted for the protection of multipurpose plant species.
