Chronic toxicity studies of gandhaka rasayana - A herbo-mineral preparation used in Ayurvedic practice.
Article in Journal of Ayurveda and integrative medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGandhaka rasayana (GR) is an important component of many Ayurvedic formulations besides being used as a standalone therapy. However, literature review revealed a chronic toxicity studies with longer duration.
objectivesTo delineate the safety profile of GR for 180 days administration in rats. MATERIALS AND
methodsWistar albino rats of both sexes weighing 150 ± 10 g body weight in groups of 20 (10 male and 10 female) for each of the three GR dose levels i.e., 0.54 g, 1.08 g, and 5.4 g/kg were employed. Carboxyl methyl cellulose was administered to the control group in equal volume. Toxicity was assessed based on the changes observed, compared to control, in body weight gain, food and water consumption, organ weight and histopathology, clinical biochemistry, and hematological parameters as per AYUSH guidelines.
resultsGR repeated dose administration caused significant changes in body weight gain, organ ponderal changes, few hematologic and biochemical parameters. Male rats administered with GR at 1.08 g/kg dose showed a significant decrease in the MCV and MCH compared to control, whereas female rat's administred with 1.08 g/kg and 0.54 g/kg dose showed a significant increase in the MCV and MCH. GR administered at 0.54 g/kg showed a significant increase in the serum glucose level in male rats, whereas female rats showed a significant elevation in the cholesterol level. GR at 0.54 g/kg and 5.4 g/kg showed a significant elevation in the serum SGPT level in male rats. These changes were not observed in female rats. Histological examination revealed mild pathological changes in organs like kidney, liver, spleen and jejunum.
conclusionThe data generated shows that GR is safe and does not have any toxicity potential at the doses used in therapeutics. Some of the changes observed were at higher dose levels which is not likely to be used clinically.
