The aim of this study was to explore acute and chronic toxicity as well as antiasthmatic potential of the ayurvedic formulation Nayopayam Kashayam on experimental animals. The present study was targeted for the study of its toxicity profile along with its antiasthmatic activity. The acute toxicity study was carried out using OECD 425 CPCSEA guideline in albino wistar rats. Oral acute toxicity study was performed at 2000mg/kg orally, which was considered as limit dose. The chronic toxicity study was carried out with administration of Nayopayam Kashayam at three therapeutic equivalent doses i.e. TED (45mg/kg, orally), TEDx5 (225 mg/kg, orally) and TEDx10 (450 mg/kg, orally) for 90 days. Further, antiasthmatic study was carried out using histamine-induced bronchospasm in guinea pig model. The results of acute toxicity studies showed that drug did not create any signs and symptoms of toxicity and no mortality was shown to an oral dose of 2000 mg/kg in rats. The results of chronic toxicity study showed that the drug even at level as high as dose of TEDx10 had no significant effect at all on hematological and body weight parameters, however mild to moderate unfavorable changes in kidney and liver were indicated. The experiential changes were not seen at the lower dose levels. The drug also showed a marked decrease in hiccups of asthma during antiasthmatic study. Hence, it is suggested that the Nayopayam Kashayam, prepared as per the traditional method, is secured/safe for utilization and treatment of asthma at the therapeutic dose level.

Aim: Frankincense tree (Boswellia dalzielii) and Kenaf (H. cannabinus) are plants abundantly found in north-western Nigeria. These plants are very popular among the locals as potent sources of ethno medicine. The present study investigates the oral acute toxicity potentials of methanolic stem bark extract of frankincense tree and Kenaf leaves, as well as sub-chronic toxicity potentials of the plants extracts on the kidney and liver of Albino rats. Study Design: Laboratory-experimental design was used for this study. Place and Duration of Study: This study was carried out between September 2019 and November 2019 at Biochemistry laboratory, Sokoto State University, Sokoto, Nigeria. Methodology: For the oral acute toxicity study, the revised “Up and Down” test (Limit Dose Test) was used to determine the LD50 of the extracts. For sub-chronic toxicity study, twenty albino rats were used for each plant, and were divided into four groups of five animals each. Group I (control), Group II (received 200 mg extract/kg body weight), Group III (received 400 mg extract/kg body weight) and Group IV (received 800 mg extract/kg body weight). All administrations were given orally for 28 days. Liver and kidney markers were determined using standard methods. Result: The oral acute toxicity test of the plant extracts at 3000 mg/kg body weight showed no mortality for 24 hours and subsequent 14days of administration. LD50 for both plants is therefore greater than 3000 mg/kg. The result shows no significant differences (p > 0.05) on liver and kidney function biomarkers investigated when Group II, III and IV are compared with control. Conclusion: This suggests that Frankincense stem bark and kenaf leaves extracts may be safe in rats at doses less than or equal 3000 mg/kg.

Acute And Chronic Toxicity

Burkea africana Hook. (Caesalpiniaceae) is used traditionally to treat ulcers, headaches, skin disease and tumors. The study investigated the acute, sub-acute and chronic toxicity profiles of the ethanolic extract of Burkea africana stem bark. Rats of either sexes were used in this study (n=10). For  acute toxicity, a single dose of 5,000 mg/kg was administered while for the sub-acute and chronic toxicity study, three doses (40, 200 and 1000  mg/kg) of the extract were administered orally for 28 and 90 days respectively. At the end of each study, the biochemical, hematological and  histological parameters were evaluated. No mortality or behavioral changes were observed in the acute toxicity study. Extract caused significant  changes in the hematological parameters after the sub-acute toxicity study. In the chronic toxicity study, the extract caused significant increase in  the white blood cell count of the 200 mg/kg group. There was significant increase in the platelet count of treated groups compared to control in the sub-acute and chronic toxicity studies, with an observed total mortality of all the animals in the 1000 mg/kg group on the 44th day. No adverse pathology was observed in the organs examined. The extract elicited a hematological response and short term consumption of the extract at low doses might be relatively safe. However, long term consumption at high doses should be discouraged.

Harmful Effects

Suryashekhara Rasa is unique mercurial preparation, which contains Parada, Gandhaka, Hingula and Vatsanabha. The quantity of Vatsanabha is equal to the sum of other ingredients, and also its antidote (Tankana) is not mentioned in this formulation. To ensure that the drug is devoid of toxicity and harmful effects, assessing the level of toxicity is important. So, this research work is an attempt to perform acute and sub-acute toxicity evaluation of Suryashekhara Rasa. Acute toxicity study of test drug was carried at a limit dose of 2000mg/kg orally in albino mice. For sub-acute toxicity Suryashekhara rasa was adminis-tered at therapeutic equivalent dose (TED) (0.35mg/kg bw po), TED x 2 (0.70mg/kg bw po) TED x 5 (1.75 mg/kg bw po) for 28 days. Acute toxicity result showed that drug did not produce any signs and symptoms of toxicity or mortality up to an oral dose of 2000 mg/kg in albino mice. The data generated during sub-acute toxicity study are indicated that it is mild toxic substance for sub-acute administration at TED dose level, may be because of alkanes which are found in functional group of aconitum ferox.

Phytochemical Components

Most of biochemical reactions in the body generates Reactive Oxygen Species (ROS), which are involved in the pathogenesis of oxidative stress-related disorders like diabetes, nephrotoxicity, cancer, cardiovascular disorders, inflammation and neurological disorders when they attack biochemical molecules like proteins, lipids and nucleic acid. Antioxidants are used to protect the cells or tissues against potential attack by ROS. Most medicinal plants possess a rich source of antioxidants such as flavonoids, phenols, tannins, alkaloids among others. These phytochemicals are currently pursued as an alternative and complimentary drug. In this study, phytochemical components, antioxidant and acute toxicity study of the methanol extract of stem bark and root of F. sycomorus were carried out using standard methods. Findings from this study revealed the presence of some diagnostic microscopical features such as calcium oxalate, starch, gum/mucilage, lignin, Aleurone grain, suberized/Cuticular cell wall and inulin but calcium carbonate was absent in stem bark but present in the powdered root. Quantitative physical constants include moisture contents (6.40% and 7.82%), ash value (7.20% and 9.30 %) in stem bark and root respectively. Carbohydrates, alkaloid, flavonoids, saponins, tannins, glycoside, steroid, triterpenes and phenols were present in all the extracts. They were found to exhibit potent 1,1,-diphenyl 2-picryl hydrazyl (DPPH) free scavenging activity. The DPPH radical scavenging ability of the extracts showed the following trend Ascorbic acid < stem bark extract˃ root extract. The LD50 of the methanolic stem bark and root extracts were found to be greater than 5000 mg /kg and is considered safe for use. Nonetheless, further

Background: The Eucalyptus globulus extractions have been used by the traditional healers to treat diseases in the study area. Our previous study revealed that the essential oil has antimicrobial and antifungal activity. This study determined phytochemical analysis, skin irritation, acute and subacute toxicity of Eucalyptus globulus essential oil in mice and rats. Methods: The phytochemicals were analyzed using GC-MS mass spectrometry. The acute toxicity study was determined at three dose levels of 1500 mg/kg, 1750mg/kg, and 2000 mg/kg. The essential oil limit test at a dose of 1000 mg/kg was administered to mice for 28 consecutive days for sub-acute toxicity study. The mice mortality, behavioral change, injury and other signs of illness were recorded once daily. Biochemical parameters were evaluated. Liver and kidney were analyzed for histopathological analyses. The 5% ointment formulation was applied to the rat skin to determine skin irritation effects. Results: The Eucalyptus globulus essential oil showed no effect on the mice at a dose of 1500mg/kg and below, but caused signs of toxicity and death at a dose of 1750mg/kg and above compared to the controls (p<0.05). The LD50 value was 1650 mg/kg. There was no significant difference (p > 0.05) in the body weights, gross abnormalities of the organs and biochemical parameters compared to the control at 1000 mg/kg subacute toxicity study. No histopathological changes were detected in the organs tested. The 5% ointment formulation did not show any abnormal skin reaction. Discussion: In the present study, the Eucalyptus globulus essential oil was comparable with other studies in terms of both chemical composition and its effects on sub-acute and topical application. Conclusion: This toxicity study demonstrated that Eucalyptus globulus essential oil is nontoxic at a relatively lower concentration.
