Colombian Indians have reportedly created a golden, carbonated drink made from coca leaf extract and plan to market it as an alternative to Coca-Cola.

A Nasa Indian company in southern Colombia plans to launch Coca Sek - which is said to look like apple cider and taste like a cross between 7-Up and ginger ale - in parts of the country this week.

David Curtidor, a Nasa who heads the community company that produces the drink told Associated Press that the beverage was an "energising drink".

He added: "It's like coffee since it is lightly stimulating."

Curtidor said the drink was also a statement against multinational companies like Coca-Cola, which he said "symbolises imperialist domination".

It is likely that exports of the drink to the US and elsewhere will be banned because of rules blocking the entry of raw coca, the plant from which cocaine is refined.
