Mugdha Rasa is one type of Kharaliya Rasayana and comes under Nirgandha, Niragni Murchana of Parada. Parada and Khatika are the main ingredients of Mugdha Rasa. This investigation is an attempt to perform toxicological study of Mugdha Rasa. Acute toxicological study and sub-acute toxicological study were carried out as per OECD guideline 425 and 407 respectively. Oral acute toxicity study was carried out at the limit dose of 2000 mg/ kg orally in Swiss albino mice. Sub- acute toxicity study of Mugdha Rasa was carried out in Albino rats and it was administered at therapeutic equivalent dose (TED), TED ×2 and TED×5. No signs of toxicity and mortality were observed Mugdha Rasa in acute toxicity study. So, LD50 of Mugdha Rasa is greater than 2000 mg/kg body weight and Mugdha Rasa can be considered assafe on acute exposure. The data generated during sub-acute toxicity study are indicated that it is not a hazardous substance for sub-acute administration at TED dose level. Higher dose levels show mild changes in parameters.

Acute Study

Background: In Charaka Samhita it has been mentioned that three medicinal substances viz. Pippali (Piper longum), Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). If they are consumed in excess quantity they will cause several adverse effects in the body. Hence in the present study Kshara has been evaluated in experimental animals in two different phases viz. acute administration at graded doses as part of acute toxicity study and sub-acute administration at fixed dose level, as part of sub-acute toxicity study, to assess the possible adverse effects if any. Objectives: To evaluate the acute and sub-acute toxic effect of Kshara in albino rats to establish the principle of Trini Dravyani Nati Upayunjita. Materials and Methods: Wister strain albino rats of either sex weighing between 150 - 200g body weights were used for experimental study. The experiment was carried out as per ‘Ayush Guidelines’ after the IAEC clearance. For Acute Toxicity - 9 Albino rats were used and for Sub-Acute Toxicity - 12 Albino rats were used. The dose calculation was done on the basis of body surface area ratio using the table of ‘Paget and Barnes rule’. Results: In Acute toxicity study no mortality and behavioral changes were observed when the drug Kshara was studied after two dose level i.e. TED X 5 and TED X 10. In Sub-acute study some behavioral changes (including cage side behavior) were observed. No mortality was observed in any of the groups. Discussion: Acute toxicity study of Kshara showed no immediate and evident toxic signs and mortality within 24 hours of observation. In Sub-acute toxicity study in all four groups, no mortality or evident toxic effects were observed, however some mild histopathological changes were observed in sub-acute study.

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.

Acute Study

Background: Lavana is used as medicine as well as Ahara since ancient times. In Caraka Samhita it has been mentioned that three Dravyas viz. Pippali, Kshara (alkali) and Lavana (salt) can be used as emergency medicine, but they should not be consumed in excess (Ati Upayunjita). Hence in the present study Lavana has been evaluated in experimental animals in two different phases’ viz. Acute administration at graded doses as part of acute toxicity study and Sub-Acute administration at fixed dose level, as part of toxic Sub-Acute toxicity study, to assess the possible adverse effects. Materials andamp; Methods: Wistar strain albino rats of either sex weighing between 150 - 200g. body weights were used, The experiment was carried out in accordance with the direction of the Institutional animal ethics committee (IAEC) after obtaining its permission (Approval number IAEC – 138/k/2018). Results: Results were drawn based on histopathological reports and biochemical reports of each group of toxicity study. Acute toxicity study has been carried out in albino rats receiving the 2 dose level maximum at up to 10 times higher (855mg/kg) then the therapeutic equivalent dose (427.5mg/kg). In Sub-Chronic toxicity: dose given was five times higher than therapeutic equivalent dose and ten times the equivalent to human therapeutic dose for duration of 30 days. Discussion: Toxicity is not found in Acute study and in Sub-Acute study moderate to high toxicity is found.

Siddha system of medicine is the eternal science of life. It is a system that has its extensive bonding with Dravidian culture, language and beliefs. The system of medicine mostly prevailed and prospered in the regions of Dravidian cultures by the great Siddhars. It’s unique as one only than other AYUSH traditional systems of medicine across India with its distinctive abundant usage of medicinal plants, metals, minerals and animal products. Siddhars used the steps of Alchemy to prepare various medicines from metallic and mineral origin for attainment elixir and various rare diseases. Siddha medicine is classified into 32 types of internal and external medicine each. Among the 32 types of internal medicine Chendhuram is a medicine shelf life of 75 years usually from herbo-mineral combinations. Arumuga Chendhuram (ARC) is a herbo-mineral formulation cited in Siddha literature ‘Siddha Vaithiya Thirattu’. ARC was orally administered at higher dose 2gm/kg to the Wistar Albino rats in acute toxicity study and during 28 days of repeated (sub acute) toxicity study, at daily doses of 12, 24 & 48mg/kg of body weight to the Wistar Albino rats. Type II collagen arthritis is another model for developing autoimmune arthritis. The immune pathogenesis mediated by T cell and B cell response to collagen. By this model, nearly 100% arthritis can be achieved. In our study, ARC after 42 days treatment reduced the arthritic swelling significantly and degree of inflammation evident to act against auto immune disorder.

Moringa oleifera (M. oleifera) Lam belongs to the family Moringaceae. It is an important multipurpose tree that is largely distributed globally and has been used almost in every aspect of traditional medicine for the treatment of various illnesses including cancers, diabetes mellitus, asthma, arthritis, etc. This study investigated the effects of oral acute and sub-acute administration of M. oleifera hydroethanolic leaf extract (MOHE) in ICR-mice. Its major phenolic compounds were also determined. Ten (10) female, 8-week old mice were grouped into control and treatment groups for acute toxicity study. A dose of 2000 mg/kg MOHE was given once to the treatment group via oral gavage. However, for the sub-acute toxicity study, 25 mice were grouped into groups A (control), B (125 mg/kg), C (250 mg/kg), D (500 mg/kg) and E (1000 mg/kg). MOHE was given via oral gavage to groups B, C, D and E daily for 28 days. Group A received only distilled water. The mice were sacrificed at the end of the experiments and samples were collected for evaluation. The results of the chemical profiling of MOHE revealed the presence of glucomoringin, niaziminine, quercetin and kaempferol as the major compounds. The treated mice in the acute toxicity study were slightly anaemic and showed evidence of stress leukogram. Moreover, a slight increase in creatinine, significant increases in AST and CK, hepatic degeneration and necrosis, none-obstructive sinusoidal dilatation, renal tubular necrosis, interstitial nephritis and renal interstitial oedema were observed. It is concluded that the LD50 of MOHE is higher than 2000 mg/kg. However, oral administration of MOHE causes acute mild anaemia and moderate hepato-nephrotoxicity in ICR-mice. Its major phenolic compounds are glucomoringin, niaziminine, quercetin and kaempferol.
