Hot Drinks on Motzaei Shabbos

On motzaei Shabbos the Zutshka Rebbe would sit and drink the customary hot drink. As he sipped his hot tea, he recited the words of Chazal and Rashi, "chamin b'motzai Shabbos melugma," with Rashi's explanation that hot liquids are a remedy or cure. Then he added, "Refuas hanefesh verefuas haguf, they heal both the body and the soul." One of the Alter Zutshka Rebbe's segulos, tried and tested as true according to his grandson Rav Shlomo, the Zutshka Rebbe of Yerushalayim, was to prescribe that any sick person drink a hot drink such as coffee or tea and wash in warm water. He explained, in the name of the Rebbe Reb Heschel, that a warm bath gets the blood circulation going, and the blood flows to the luz bone. The Tur and Beis Yosef cite the Shibolei Leket: "There is a limb found in man named the niskoy, which remains intact until the resurrection. Even after all the bones have decomposed, this limb remains. This limb derives its sole nourishment from the seudah of Melava Malka. Therefore, we eat on motzaei Shabbos to nourish this limb." Since this limb did not take part in the sin, it was not punished and does not decompose. This is cited by the Pri Megadim. The luz bone, or niskoy, did not benefit from the sin of eitz hadaas, and so it was not included when Chava was cursed to bear children in pain. It is nourished only by the Seudas Melaveh Malka. The Alter Zutshka concluded, "If the luz can reconstruct the entire body and heal it for the resurrection of techiyas hameisim, surely it can heal just one limb or organ of that body as well."
