INTIMATION FOR BODHIKA SEMINAR - 28/09/2022
DEPARTMENT OF RASA SHASTRA AND BHAISHAJYA KALPANA
Pottali Kalpana
is a unique preparation mentioned in Ayurvedic texts. Rasagarbha pottali, the experimental drug is a formulation
developed by Acharya Vasudev Mulasankara Dvivedi and Harisankar Sarma, first
recorded in the book, Rasasastra by PHC Murthy. The present study was aimed at
assessing the acute and sub-acute toxicity of orally administered Rasagarbha pottali. Rasagarbha Pottali was prepared in gandhaka dravapaka method. Further analyses like XRD, XRF and PSA
done. Acute toxicity test was performed on Wistar rats at a single oral dose of
1000 mg/kg for 14 consecutive days. General behavioural adverse effects and
mortality were determined. In the sub-acute study, Rasagarbha Pottali was administered orally at doses of 100, 150 and
200 mg/kg daily for 28 days to Wistar rats. Sections of brain, heart, lungs,
livers, stomach, kidneys and reproductive organs were removed for histological
studies. Acute toxicity study showed that the oral LD50 value of RGP
was above 1000 mg/kg. The sub-acute toxicity study did not produce any
observable symptoms of toxicity and no significant variation in body weight,
organ weights, haematological and biochemical parameters or mortality in all
treated rats. Mercury was detected at levels below detection in the liver
tissue of high-dose females via ICP-MS. It was concluded that drug RGP did not
cause any systemic adverse effect in the acute and sub-acute oral toxicity
trials in rats up on oral administration and is safe at all doses tested over a
period of 28 days in rodents. Thus 100- 200 mg/Kg body weight of the RGP is
safe to use in preclinical pharmacological efficacy analysis up to a month
period.
