Purple-bluish tongue is associated with platelet counts, and the recurrence of epithelial ovarian cancer

Abstract

The ratio of P(B) to P(R) greater than 0.71 could serve as an indicator for purple-bluish tongue diagnosing used in symptom pattern identification in Traditional Chinese Medicine. Purple-bluish tongue, associated with increased platelet counts, was also closely correlated with the recurrence of epithelial ovarian cancer.
