The Differences Between a Yid and a Goy

The Gemara suggests that the Shichvas Zera of a Nochri has different properties from that of a Jew, since the Nochri eats non-Kosher foods and is physically affected by his diet.

The Chasam Sofer (Teshuvos YD 175) writes that this Gemara is relevant in practice. He rules that we cannot assume that a medical treatment that was tested successfully on a Nochri will also be successful on a Jew.

Rav Elyashev shlita pointed out that the Chasam Sofer writes that the physical characteristics of a Yid are different than a Goy, and that what applies to one may not apply to the other. Therefore, said Rav Elyashev, how much more so regarding the mind/soul?
