Is green tea good to drink while on sovaldi and ribavirin ?

In moderation OK.: No contraindications. So in moderation I do t expect any problems.

For Tea Sellers, Yes: ribavirin & sofosbuvir: single molecules promoted for hepatitis C treatment, look up on Google, Google images, wikipedia, rxlist.com, etc. The standard for outcome data is double-blind, placebo controlled, prospective clinical trials testing humans judged similar, half taking agent being tested, half take a fake version, then comparing all outcomes, good & bad. Who would do such a trial with tea?
