The opening as it read in 2005

Niddah (or nidah , nidda , nida ; Hebrew ), in Judaism , is technically a state of minor "exclusion" when a woman is menstruating and for about a week later until she immerses in a ritual bath known as a mikvah . Niddah is the main category of a group of laws and customs that is generally called by the euphemism family purity ( taharat hamishpacha ). Niddah is also the name of a tractate (volume) in the Talmud , which deals almost exclusively with the subject.1
