The Sidr (Zizyphus Spina Christi) is a multipurpose tree that has been used for medicinal purposes in many cultures, especially the Arabian region. It has been cultivated in gardens, farms and private yards. It is a long-lived and drought resistant species that grows in various types of soil as it tolerates hot and dry climates.
Besides its medicinal uses, the Sidr has a sweet fruit that is considered to have cooling effects on the body. The fruit contains 3 to 4 seeds and is light green in color when unripe. When ripe, the fruit has a purplish-black colour and is soft and juicy. The fruit’s phytochemicals include beutic acid, christanin A, christanin B, and cyclopeptides 14.
A study found that the extract from Sidr leaves has anti-inflammatory and antioxidant properties, as well as the ability to boost immune system function. It also has a potential to cure enterobiasis vermicularis, a common parasitic infection that affects the intestines. The study tested the effect of two doses of Sidr leaves extracts (10 and 20 mg/day) on EV infected stool samples. The results showed that the Sidr leaves extracts significantly reduced worm count in both groups from the first to the second week.
