Tribute to Rebbetzin Ruchoma Shain a'h Part II

In All for the Boss, Rebbetzin Shain a'h mentioned that when she was a child, she was ill and her father, the tzaddik, Rav Yaakov Yosef Herman ztz'l asked her to lie on his talit as a segula to heal her ear it was, I believe. I don't know the origin of this segula nor have I heard of it anywhere else but she claimed that it worked.
