According to Tibb, Chishti in "The Traditional Healers Handbook" says, “These are caused by excess gas. Use a purgative and correct digestion. Relief of gas can be had from ground anise in rose water or honey.”
Suyuti says of endive (Arabic: Hindiba) “The endive changes its temperament according to the season. In summer it is hot, in winter cold. Its powers fall to naught at the end of each season. It prevents both hot and cold diseases of the liver. It causes to disappear the flatulence produced by vinegar and by sugar. It is used in decoctions and in the syrup of dodder. A traditional saying is as follows: Eat endives and do not belch, for verily there is not one single day that drops of the water of Paradise do not fall upon them. So says Abu Nu’im.”
