R. Abhu in the name of R. Yohanan היתר מצטרף לאיסור only for Nazir. Source is משרת (R. Akiva)

Abaye challenged – also other prohibitions

Rav Dimi – those cases are כזית בכדי אכילת פרס

Abaye challenged – משרת teaches טעם כעיקר. Applies to all prohibitions acc to majority

From where does R. Akiva learn טעם כעיקר?

Meat and Milk

Nonkosher Pots

Why does R. Akiva not apply היתר מצטרך לאיסור to all prohibitions?
