Use

In the badia: Al-Khatīb: stomach, diabetes.

Field data: diarrhoea, diabetes, toothache (pulp on the teeth), cathartic (strong!).

In literature: cathartic, anti-diabetic; violent purge (pulp); pulp is: diuretic, anti-epileptic, anti-blenorrhoeic, strong cathartic (mixed with Arabic gum, to mitigate the effects), the emptied fruit, filled with water and honey, is drunk for rheumatism, gout, dropsy, ascites, while cataplasms are good for arthrosis, seeds are anti-diabetic and anthelmintic, the fruit is used also as abortifacient (drinking water in which fruit is macerated overnight) and for poisonous bites; dog, insect and snake bites, laxative, pain in joints, hair colour (leaves, seeds, roots and dried fruit); it is used also in many composed medicines. The colocynth is well known from ancient times. Greeks and Romans used it, and it was even cultivated in Cyprus for a long time. Common in the whole area, it is used at a popular level. Fatal cases of poisoning from overdoses of colocynth are not rare, but they represent a small percentage given its wide use. Some of its beneficial effects are, in fact, recognized by pharmacological research.

Its use as forage has not been scientifically investigated.
