So he answers with a moshul. There was a person who took ill with a disease and called for a doctor to heal him. The doctor said that he will prepare a medicine made up of terribly bitter herbs and spices which he will have to swallow. Although it is extremely bitter and difficult to swallow, but if he nevertheless takes it every day, he will eventually be healed. Then the doctor said that if he wants there is an alternative. If he wants, he can be sealed up in a room together with these atzei boysem, these strong, bitter herbs, and if he remains in that room for many days, and with the air intensely saturated and filled with the fumes and smell of the trufah, he will be healed by merely breathing in that air.
A Good Shabbos!
