Abstract: A process for producing a purified extract comprising between about 40% and about 90% theaflavins is provided. Purified theaflavin extract produced by the disclosed process is provided which comprises less than about 5% TF1, between about 10% and about 60% TF2a, between about 5% and about 35% TF2b, and between about 10% and about 65% TF3. Individual dosage compositions are provided for the control of a physiological disorder comprising about 5% to about 95% theaflavins in a pharmaceutically acceptable vehicle or a dietary supplement vehicle. Further individual dosage compositions are provided which comprise an effective amount of substantially only one theaflavin species selected from the group consisting of TF1, TF2a, TF2b, and TF3. Individual dosage compositions are provided which comprise an effective amount of substantially only two theaflavin species selected from the group consisting of TF1 and TF2a, TF1 and TF2b, TF1 and TF3, TF2a and TF2b, TF2a and TF3, TF2b and TF3.
