Tirunelveli : Drinking a herbal concoction for diabetes to prove its efficacy to the public proved fatal for a siddha doctor and three of his patients who he gave it to as all of them collapsed and died at a village in the district, police said.
They said Muthupandi was running a clinic at Tenkasi for diabetes and blood pressure patients. He also used to visit patients at nearby Azhagapuram village.
He visited the village, but people there expressed doubts about the efficacy of his concoction. To clear their doubts, the doctor first drank it himself and then gave it to four patients, police said.
All of them fainted and were rushed to the government hospital at Tenkasi. Muthupandi and three others died en route to the hospital, while the other patient was hospitalised and is reportedly in a critical condition, police said.
