Emesis is defined as a forceful expulsion of stomach contents via the mouth. The adverse effects of available anti-emetic drugs potentiate us to evaluate natural products to explore effective natural anti-emetics with fewer side effects. The fruits of Illicium verum Hook. f. were selected for anti-emetic activity based on their folkloric use against gastrointestinal complaints. Crude methanolic extract and its aqueous, dichloromethane, ethylacetate and hexane fractions were evaluated using the copper sulphate-induced chick emesis model. Emesis was induced by the oral administration of copper sulfate 10 ml/kg body weight and metoclopramide (150 mg/kg p.o.) as a standard anti-emetic drug. The anti-emetic effect was observed by calculating the mean decrease in the number of retches compared to that of the control. Methanolic extract and its fractions were tested at 25, 50 and 75 mg/kg oral doses. Among all tested fractions, ethyl acetate showed the highest (94.46%), and hexane showed the lowest (56.30%) anti-emetic activity at 50 mg/kg. Further, isolation and purification from the same fractions are in process to discover effective natural anti-emetic compound(s) with less unwanted effects.

Medicinal plants are the gift of nature and play an important role as a part of our diet to maintain health. They also serve as a versatile weapon to combat several diseases. Every civilization has its own experience and knowledge of the therapeutic uses of plants. The belief and observations regarding traditionally used medicinal plants increase people's interest in using them against urolithiasis. Urolithiasis is a common problem that has been afflicted for centuries and has a high recurrence. Of the world's population, about 12% suffer from urolithiasis. All over the world, in different countries and cultures, people use plants to prevent and cure kidney stones according to their ethnopharmacological information. These formulations are very effective. That's why they have been used for hundreds of years. This review covers the eighty (80) medicinal plants of the most cited family Asteraceae against urolithiasis and their historical antiurolithiatc background shared in well-known books of Dioscorides, Pliny the Elder, Al Razi and Ibn Sina. This information was extracted to compose antiurolithiatic plants with their parts and formulations used in 21 countries such as Algeria, America, Australia, China, India, Iran, Italy, Jordan, Jordan, Kyrgyzstan, Lebanon, Libya, Mexico, Morocco, Pakistan, Palestine, Philippine, Spain, Tunisia, Turkey and Uzbekistan. Scientifically proven pharmacological activities of the same part of the plant have direct (litholytic) and direct pharmacological effects like analgesic, anti-inflammatory, antioxidant, astringent, demulcent, diuretic, litholytic, lithotriptic, antiurolithiatic, antispasmodic, ACE inhibition and Phospholipase A2 inhibition also shared as a plausible mechanism of action. The route of administration is oral in all cases. Hopefully, this book will be useful for the general public and attract the scientific world for antiurolithiatic drug discovery. This valuable ethnopharmacological information will provide opportunities for the future research and development of new natural antiurolithiatic compounds.

Brushites are the most commonly found phosphate stones in the kidneys, ureters and urinary bladder. The study was conducted to observe the possible growth patterns of brushite crystals in the gel for 14 days. The crystal formation was observed as a bullet, needle, platy, columnar shaped and their aggregates. Magono and Lee's meteorological classification further explained these shapes. Besides the morphology, the average size, number and weight of crystals were also observed on the 7th and 14th days. Energy Dispersive X-ray, Fourier Transform Infra Red spectroscopy and Scanning Electron Microscopy were used to characterize the crystals. These results can help to determine the promotion, modulation and inhibition of the crystals, which will be helpful in evaluating the risk factors and prophylactic management of brushite-type urinary stones.

Three commonly used legumes, Macrotyloma uniflorum (Lam.) Verdc., Phaseolus lunatus Linn., and Phaseolus vulgaris Linn. were subjected to determine their minerals and phytic acid contents to correlate their nutritional and medicinal properties. The atomic absorption spectroscopic method was used to quantify essential minerals, while the spectrophotometric method was used for phytic acid estimation. Fe, Mg, Mn, P and Zn were recorded in reasonable quantities, Ca and Cu in moderate, and K in small amounts in the seed flours of all the three tested legumes. Maximum Fe and Zn content (0.38 and 0.40 mg/g) were recorded in P. vulgaris, while M. uniflorum delivered high content of Mg, Mn, P and Ca (0.21, 0.20, 77.94 and 0.04 mg/g) and 0.04 mg/g Cu was recorded in P. lunatus. The highest level of phytic acid (37.00 mg/g) was recorded in M. uniflorum at 519 nm. The estimated quantities of minerals and phytic acid provide an excellent opportunity to conclude that all three tested legumes could be used as food to achieve nutritional and health-related functional benefits.

Monosodium urate monohydrate crystals are deposited in peripheral joints, causing gout and eliciting an intense localized inflammatory attack. In contrast, collecting ducts and medullary interstitium is a urinary calculus, which causes dysuria, nausea and hematuria. The purpose of the present study is to observe possible growth patterns of monosodium urate monohydrate crystals. The crystals were grown in test tubes using a single diffusion gel technique and were observed on the 7th,14th, 21st, 28th, and 40th days. Needle and spherulite-type crystals were observed on the 14th day, while arboresque, crystal sheaves, densely branched, dumbbell, mushroom-type spherulites, plumose and hexagonal prismatic crystals were observed for the first time. After the 40th day, complete spherulites were observed with their aggregates. The crystals were characterized by Scanning Electron Microscopy, Energy-Dispersive X-ray and Fourier Transform infrared spectroscopies. The pattern of MSUM will help determine the role of different natural products in the modulation, inhibition or promotion of these crystals by affecting the shape, size, transparency, approximate number and total mass of growing crystals. In case of inhibition or modulation, it will help evaluate prophylactic management. In contrast, the promotion of the crystal will give an idea about the risk factors of gout and kidney stones.

: Analgesic, anti-inflammatory and diuretic activities of the methanol extract of two varieties of Cicer arietinum viz black or Desi and white or Kabuli were tested in 200 and 400 mg/kg doses. For the analgesic effect of the extracts, acetic acid-induced writhing, tail immersion and hot plate tests were employed in mice. The anti-inflammatory activity was carried out by carrageenan-induced inflammation in rats, whereas the diuretic action was determined using metabolic cages for rats. Animals were divided into six groups (n=7): (1) Control (2) Standard (3) MECAB 200 (4) MECAB 400 (5) MECAW 200 (6) MECAW 400. All extracts and standard drugs were administered orally. Acute oral toxicity of the extracts was also checked in mice up to 2000mg/kg dose, which showed a favorable safety. Significant analgesic and anti-inflammatory effects were observed. The results of diuretic activity were significant at the 12th and 24th hrs. Therefore, it is concluded that the methanol extracts of the seeds of Cicer arietinum have analgesic, anti-inflammatory and diuretic potential.

Macrotyloma uniflorum, commonly known as horse gram or kulthi bean, is grown as a pulse for livestock and human consumption. The beans contain about 1.3% fat, 18% protein, 15% carbohydrate, and vitamins and minerals. Traditional medicine uses it as an antihyperglycemic, antioxidant, antihypertensive and diuretic. Other important medicinal uses include the treatment of renal stones, obesity, piles, oedema and fever. The present study evaluated analgesic (by acetic acid-induced writhing, hot plate and tail flick tests in mice) and anti-inflammatory (carrageenan-induced paw oedema in rats) activities of Macrotyloma uniflorum fixed oil (MUFO). Four groups were included in the study: Group I: Normal Saline Control (2ml/kg), Group II: MUFO (2ml/kg), Group III: MUFO (4ml/kg), and Group IV: Standard Acetyl salicylic acid (ASA 300mg/kg). All results were significant; however, the tail flick and paw oedema tests observed a delayed onset of action. The oil's acute oral toxicity was also checked in mice and was found safe up to a 4ml/kg dose, as no signs of toxicity and mortality were observed. It is concluded that Macrotyloma uniflorum fixed oil may possess analgesic and anti-inflammatory activity, which can be related to a peripheral mechanism of action.

Background: Phaseolus vulgaris, commonly known as kidney bean, has been studied previously for pharmacological properties such as antidiabetic, antioxidant, analgesic, anti-inflammatory, antifungal, and antibacterial properties. Various extracts of the seeds have been researched except fixed oils. Objective: Therefore, the present study aims to investigate the behavioral activity of fixed oil extracted from Phaseolus vulgaris seeds. Methodology: Hole board, light and dark, stationary rod and open field tests were used for behavioral evaluation. Four groups were made with seven mice in each : (1) Control = Normal saline 2ml/kg (2) Phaseolus vulgaris fixed oil = PVFO 2ml/kg (3) PVFO 4ml/kg (4) Diazepam (1mg/kg) as standard. All treatments were given orally 30 minutes before the performance of tests. In the hole board test, PVFO 4ml/kg decreased the number of head poking (p≤0.01). Results: In light and dark tests, PVFO in both doses reduced the time spent in the light compartment (p≤0.01). In the open field test, the number of peripheral lines crossed was decreased (p≤0.05), whereas in the stationary rod test, no effect was observed by any dose of PVFO. Conclusion: Results indicate that Phaseolus vulgaris fixed oil does not affect memory or learning in mice and may possess a dose-dependent sedative hypnotic effect.
