Sudarshana powder (SP) is an Ayurvedic preparation, which contains 53 herbal ingredients along with 50% of Andrographis paniculata and is clinically used with bees honey. This study was aimed to determine the safety profile of the SP, and its novel preparation Sudarshana suspension (SS) on male Wistar rats and tolerance studies were conducted for healthy adult volunteers. Acute and subacute toxicity studies of the SS and hot water extract of SP were assessed in Wistar rats by observing the general behavior, analyzing biochemical and haematological parameters, and pathological observation. Healthy consented adult volunteers (n = 35) of either sex were selected, and tolerance studies of SS were tested by measuring the biochemical and haematological parameters. There were no significant ( p > 0.05 ) changes observed in the treated animals with SS and hot water extract of SP compared with control in body weights, food intake, and water consumption as well as the biochemical and haematological parameters. Histopathological studies revealed no significant ( p > 0.05 ) changes in the liver, heart, and kidney tissues. The experimental results suggest that novel formulation SS was potentially safe for chronic administration in rats, and no significant differences ( p > 0.05 ) were observed in tested parameters on day 3 and day 8 when compared to the day 0 (baseline) values in healthy volunteers. Healthy volunteers did not report any adverse effects or any other complications during the treatment period and the follow-up period. Therefore, it can be concluded that the novel preparation Sudarshana suspension does not cause any significant toxic effects on the blood parameters in animal and human models.

A polyherbal drug composed of leaves of Murraya koenigii L. Spreng, cloves of Allium sativum L., fruits of Garcinia quaesita Pierre, and seeds of Piper nigrum L. is a popular drug which has been used by indigenous practitioners in Sri Lanka for the treatment of diabetes mellitus and dyslipidemia. The acute toxicity assessment was conducted, following a single oral dose of 0.25–2.0 g/kg in healthy rats, and rats were observed up to 14 days. The hot water extract (1.0 g/kg) and the water : acetone extract (0.5, 1.0, and 1.5 g/kg) were administered to Wistar rats for 28 days in the subchronic study. Hypoglycemic and antihyperglycemic activities (dose response studies) of cold water, hot water, and water : acetone extracts of the polyherbal mixture were evaluated at the doses of 0.5, 1.0, and 1.5 g/kg in healthy and streptozotocin-induced diabetic rats (70 mg/kg, ip), respectively. Acute toxicity study showed that the polyherbal drug did not cause any change in animals throughout the experimental period of 14 days. The administration of the hot water extract and the water : acetone extract of the polyherbal drug for 28 days did not produce changes in the selected biochemical and hematological parameters in Wistar rats (p > 0.05). The histological assessment corroborated the biochemical findings with no significant treatment-related changes in the kidney and liver. The treatment of polyherbal drug significantly lowered the serum glucose concentration compared to the diabetic control rats (p < 0.05) while it did not lead to a severe reduction of glucose concentration in healthy rats. The hot water and water : acetone extracts of the polyherbal drug showed a statistically significant improvement on total area under the glucose tolerance curve in diabetic rats (p < 0.05), reflecting dose-dependent antihyperglycemic effects of the drug. Based on the results, we conclude that the aforementioned antidiabetic polyherbal remedy is free of toxic/adverse effects at the equivalent human therapeutic dose in healthy Wistar rats and would be a safe therapeutic agent for long-term treatments.

Abstract: The common plantain (plantago major) contains the compound aucubin which has been demonstrated to have theraupetic effects in improving liver cells as hepatoprotector. The objective of this study was to reveal the histopathological features of the liver of wistar rats administered with the hot water extract of Plantago major after induction with carbon tetrachloride (CCl4). This study was a laboratory experimental research employing 14 wistar rats; two rats were used as the negative control fed with regular pellets for 5 days, two rats as the positif control fed with pellets containing CCl4 of 0.05 cc for five days, five rats as treatment group receiving pellets containing CCl4 of 0.05 cc for five days and were fed with regular pellets afterwards, and five rats received pellets containing CCl4 of 0.05 cc for five days and were administered with the hot water extract of Plantago major 0f 1.6 cc. Results showed that rats in the negative control exhibited normal macroscopic and microscopic features. In the positive control group, the microscopic features demonstrated liver cells with steatosis.  Meanwhile, the rats administered with the water extract of Plantago major showed liver cells which had regenerated. It is concluded that the administration of the water extract of Plantago major can improve the liver cells by diffuse regeneration. Keywords: plantago major, regeneration, steatosis , wistar rats     Abstrak: Daun sendok (Plantago major) mengandung senyawa aucubin yang telah terbukti berkhasiat memperbaiki fungsi sel hati dan sebagai hepatoprotektor. Tujuan penelitian ini adalah untuk melihat gambaran histopatologik hati tikus wistar yang diberikan air rebusan daun sendok pasca induksi karbon tetraklorida (CCl4). Penelitian ini merupakan penelitian eksperimental laboratorium dengan menggunakan 14 ekor tikus wistar, dua tikus digunakan sebagai kontrol negatif dengan pemberian pellet biasa selama 5 hari, dua tikus sebagai kontrol positif yang diberikan pellet yang mengandung CCl4 dosis 0,05 cc selama 5 hari, lima tikus sebagai kelompok perlakuan dengan pemberian CCl4 dosis 0,05 cc selama 5 hari dilanjutkan pellet biasa, dan lima tikus diberikan CCl4 0,05 cc selama 5 hari dilanjutkan pemberian air rebusan daun sendok dosis 1,6 cc. Hasil penelitian ini menunjukkan gambaran makroskopik dan mikroskopik normal pada kelompok kontrol negatif. Pada kelompok kontrol positif gambaran mikroskopiknya menunjukkan sel hati dengan steatosis. Kelompok tikus yang diberikan air rebusan daun sendok gambaran mikroskopiknya menunjukkan sel-sel hati yang mengalami regenerasi.

AbstractTurmeric (Curcuma longa) is a widely used spice that has various biological effects, and aqueous extracts of turmeric exhibit potent antioxidant activity and anti-inflammatory activity. Bisacurone, a component of turmeric extract, is known to have similar effects. Oxidative stress and inflammatory cytokines play an important role in ethanol-induced liver injury. This study was performed to evaluate the influence of a hot water extract of C. longa (WEC) or bisacurone on acute ethanol-induced liver injury. C57BL/6 mice were orally administered WEC (20 mg/kg body weight; BW) or bisacurone (60 µg/kg BW) at 30 min before a single dose of ethanol was given by oral administration (3·0 g/kg BW). Plasma levels of aspartate aminotransferase and alanine aminotransferase were markedly increased in ethanol-treated mice, while the increase of these enzymes was significantly suppressed by prior administration of WEC. The increase of alanine aminotransferase was also significantly suppressed by pretreatment with bisacurone. Compared with control mice, animals given WEC had higher hepatic tissue levels of superoxide dismutase and glutathione, as well as lower hepatic tissue levels of thiobarbituric acid-reactive substances, TNF-α protein and IL-6 mRNA. These results suggest that oral administration of WEC may have a protective effect against ethanol-induced liver injury by suppressing hepatic oxidation and inflammation, at least partly through the effects of bisacurone.
