Brewer's: Doves' Dung
In 2 Kings vi. 25, during the siege of Samaria, “there was a great famine ... and ... an ass's head was sold for fourscore pieces of silver, and the fourth part of a cab of dove's dung [hariyonim ] for five pieces of silver.” This “hariyonim” was a plant called chickpea, a common article of food still sold to pilgrims on their way to Mecca.
“In Damascus there are many tradesmen whose sole occupation is preparing [hariyonim] for sale. They have always been esteemed as provision meet for a lengthy journey, and are a necessary part of the outfit of all who travel in the remote parts of Syria and Asia Minor.” —Bible Flowers, p. 71.
