The Healing Power of Ashar Yatzar

Numerous stories depict the power of Asher Yatzar said properly with understanding and intent, and the merit of furthering its recital, actions which have in the past brought about complete recoveries even from Polio (well known story of the Chazon Ish).

Rav Mendel Weinbach, Rosh Yeshiva of Ohr Sameach, recounts a remarkable story of the power of Asher Yatzar. A father of a six year old autistic child decided to sponsor 300 posters of Asher Yatzar, placed outside of bathrooms, to help his son. The next morning his son woke up and began to speak, his autism was gone.

The Seder Hayom even codifies, "One should make this bracha with proper kavana, and say every word etc., and if one is complete in his thoughts… he will not become sick his entire life, nor will he need a doctor or healing, and therefore, one must make the bracha with complete intention and full cognizance, to the Healer of all mankind and the wonderous creator"..
