Yoga guru Ramdev on Monday claimed that regular practice of seven breathing exercises or pranayams popularised by him have successfully 'cured' cancer within six to nine months.

"I have no intention to get into any controversy. I am doing my job, let others do their job," he said referring to comments by Union Health Minister Anbumani Ramdoss who had doubted his claim that serious ailments could be cured through yoga.

"The problem stems from the fact that others are interfering in my work," he told a press conference in Bhubaneshwar.

"Cancer of the breast, liver, prostate, uterus, pituitary gland, brain tumours and even leukaemia, can be cured by practising the seven breathing exercises," he claimed.

These claims were based on documentation and patients in hundreds have benefited, he said. "Some other ingredients like wheat grass juice and those derived from neem and tulsi leaves are also administered to patients alongside the breathing exercises."

The yoga guru said he believed that allopathic medicines had the utility and was needed in emergencies, but none should frown on time-tested yogic exercises.

"Otherwise, the health department should be renamed as allopathic department and the health minister as allopathic minister," he remarked.

Ramdev, who is on an eight-day visit to Orissa, is scheduled to hold a six-day yoga science camp from January 3.
