AN Indian doctor believes that kava should be consumed in moderation if someone does have to drink it.
Dr Nitin Sadavarde, an anaesthetist for brain and orthopaedic surgeries, said excessive drinking of kava affected the nerve system in the brain.
"It's OK if you are taking a bowl or two. Some patients come to India from Fiji and they have stated about kava consumption," he said.
"Alcohol energises people but it's not good too, while kava slackens people a bit. The effect of kava is on the central nervous system.
"If taken in large quantities and very often, then it can have effects on the nerve system in the brain."
Dr Sadavarde, who is in the country with the Sahyadri Hospitals team, said excessive consumption of kava also affected the liver. He said it also made people drowsy and lazy.
"It is difficult to say how much can affect but it depends on each individual, how much they can tolerate.
"People should drink kava moderately but if possible, don't drink it," he said.
Local doctors have also stated previously that kava and alcohol should be consumed in moderation.
