Q. Lekvod Horav. This is for someone that needs a delicate medical operation. It is usually assumed by some that the month of Iyar is propitious for Refuos and healing. Is that true? What is the source?
A. Chassam Soffer (Talmud Shabbos 147b) mentions that since Sh’muel teaches: ‘All medicinal drinks are effective from Pesach to Shavuos’, that time is indeed favorable for healing.
Seforim assert that a source is the name of the month itself since the Hebrew letters of this name of this month, ?’0;??’4;?, are an anagram for the posuk (Shemos 15: 26) ‘Ani Hashem Rofecha’. or “I am Hashem, your healer.”
Besides, the month of Iyar is also known as Chodesh Ziv or the month of radiance and health.
Ta’amei HaMinhagim quotes Bnei Yissaschar who maintains as the Rambam teaches that most weakness and illness come from foods which do not accord and harmonize with a person’s nature or composition. Since the Mann began to fall during this month and it was a perfect food from which no sickness, pain or even waste matter resulted and even cured those who were ill – Hashem left the curative nature of the month in effect until our days. Accordingly, Iyar is indeed a time of healing.
Horav Shlomo Miller’s Shlit’a opinion is similar.
