Talk:Rabbi Zeira's stringency

I wonder why the stingincy is attributed to R' Zeira. He is the one that quoted it not the establisher.

א"ר זירא בנות ישראל החמירו על עצמן שאפילו רואות טפת דם כחרדל יושבות עליה שבעה נקיים Original text taken from Talmud Nidah 66 the Jewish had practiced this, and the custom was noted during the discussion. — Preceding unsigned comment added by 65.219.241.26 (talk • contribs)
