She left for Britain by a private aircraft from the international airport here along with her 10-member entourage, police said.
Camilla and the 10 others had arrived here on October 27 and checked into Dr Issac Mathai's Soukhya Holistic Health Centre in Whitefield to undergo ayurvedic treatment.
She underwent several ayurveda and naturopathy procedures like yoga, mud therapy and hydro-therapy and was on a South Indian vegetarian organic diet, sources in the facility said.
Dr Mathai has been a health adviser to the British Royal family for the past two years. This was Camilla's second visit to Soukhya.
Soukhya practises different systems of medicine like ayurveda, naturopathy, homoeopathy, yoga and other therapies on an organic farm.
