Party's Politburo member Brinda Karat, who had taken on Ramdev earlier too, said there was an online discussion on the 'Putrajeevak Beej' medicine suggesting that it helps produce a son, and this was "branding on part of Ramdev".
"Clearly, this is how he is branding the drug. This is completely against the PNDT (Pre-Natal Diagnostic Techniques) Act. It is outside the ambit of the law. And he should be prosecuted for this...On two grounds, one the PNDT Act and two, even the Consumer Protection Act.
Karat had taken on Ramdev earlier when she had alleged that medicines his pharmacy produced contained human bones and animal parts.
Opposition MPs led by JD(U)'s K C Tyagi had yesterday sought a ban on the product and sought stringent action against the manufacturer in the Rajya Sabha.
Earlier today, the yoga guru had rebutted charges that the medicine was being sold for conceiving a male child and claimed that he was being targeted through "lies" to defame the Prime Minister.
