However, he said a disclaimer will be added on the package of the medicine 'Putrajeevak Beej' that it does not promise a male child and claimed it is named so after the scientific name of the herb 'Putranjiva roxburghii Wall'.
"MPs who have no clue about Ayurveda should be ashamed and should apologise to the nation. The medicine (pack) does not say anywhere that it helps in producing a son," he told a press conference here, and demanded an apology from JD(U) MP KC Tyagi, who raised the issue in Rajya Sabha yesterday, accusing him of resorting to "lies".
"The name has simply been derived from its scientific name 'Putranjiva roxburghii Wall' and has got nothing to do with the promise of a son. Lying in the Parliament is a national crime," he said.
Calling himself a "fakir" (ascetic), Ramdev, who had openly supported Narendra Modi's prime ministerial campaign, repeatedly invoked the Prime Minister's name and said not only he but the PM was being "unfairly" targeted through these "falsehoods".

According to Ramdev, the opposition was latching onto every issue to target Modi, who, he said was focusing on developing the manufacturing sector as well agriculture.
"While Modi is trying to find a balance between the two, the Opposition wants him to fail on both the fronts. He should be given time," he said, evading a direct reply on the Land Acquisition Bill.
Ramdev was recently made Haryana's brand ambassador by the BJP government there.
