Nso are sacred prohibitions or taboos that govern behavior and practices within the Igbo community. They are considered inviolable rules set by the ancestors and the divine forces to ensure order and harmony.

Nso (Onwa) Nwanyi pertains to the monthly period of menstruation and its implications on spiritual practices, particularly Igo Mmuo (ritual veneration). This post gets into the reasons why menstruating persons should relax from Igo Mmuo during their period, the energy dynamics involved, and the spiritual significance of menstrual cycles.
