Christ’s thorn jujube is a hardy, spiny tree of the dry lands of Africa and the Middle East, valued for its fruit, its honey, and its place in folk remedies. Few plants are sacred in two faiths, but this one is tied to Jesus’ crown of thorns in Christianity and to a holy tree in the Quran.1PubMed Central.

What Christ’s Thorn Jujube Looks Like and Where It Grows
It grows as a shrub or small tree. It has thorny branches, small yellow-green flowers, and fleshy, edible fruits.3International Journal of Scientific Research and Engineering Trends. A Short Review on Botany, Phytochemistry and Medicinal Potential of Christ’s Thorn Jujube In Arabic-speaking countries it is widely called sidr, a name you will see on honey jars and herbal labels. Its wood is very hard.4crownflora.com. Christ’s Thorn Jujube
The thorns grow in pairs along the branches. Clusters of small round fruits ripen from green to yellow, and older trees can grow broad crowns that people gather under to escape the sun.
The tree is native across Africa and the Middle East and grows in arid and semi-arid places. It copes well with drought and poor soil.5International Journal of Scientific Research and Engineering Trends. A Short Review on Botany, Phytochemistry and Medicinal Potential of Christ’s Thorn Jujube Trees vary a lot from place to place, with fruits weighing from under 1 g to almost 8 g.6Elsevier / Journal of Applied Research on Medicinal and Aromatic Plants.

How to Tell It Apart From the Common Jujube
Christ’s thorn is very similar to the common jujube, and the two are hard to tell apart.7Weeds Australia. Christ Thorn, Christ’s Thorn, Syrian Christ Thorn, Christ-thorn Jujube, Jujube, Crown Of Thorns Tree Fruit color is one useful clue. Christ’s thorn fruit is usually yellow when ripe and turns reddish-brown as it dries, while common jujube fruit is dark reddish-brown when ripe and turns black as it dries.8Weeds Australia. Christ Thorn, Christ’s Thorn, Syrian Christ Thorn, Christ-thorn Jujube, Jujube, Crown Of Thorns Tree
This matters when you shop. The “jujube” or “red date” in Asian grocery stores and supplements is usually common jujube, and health claims studied on common jujube don’t automatically apply to Christ’s thorn. Checking the species name on a label tells you which plant you are buying.
Why It Is Linked to the Crown of Thorns and the Quran
Christian tradition identifies the tree as the thorn bush used to crown Jesus before his crucifixion, as described in Matthew, Mark, and John.9PubMed Central.

The ethnobotany of Christ’s Thorn Jujube (Ziziphus spina-christi) in Israel Local tradition and old sources also tie it to the “bramble” in the Book of Judges.11PubMed Central.

The ethnobotany of Christ’s Thorn Jujube (Ziziphus spina-christi) in Israel
The Gospels say soldiers plaited a crown of thorns but never name the plant. The case for Christ’s thorn is practical: it is a common local shrub with long, sharp thorns and flexible branches that could be twisted into a wreath. It is best read as a long-held tradition, not a settled historical finding.
In Islam, the Quran mentions the lote-tree twice, and it is commonly identified as this species.13PubMed Central. The ethnobotany of Christ’s Thorn Jujube (Ziziphus spina-christi) in Israel One passage places it at the “utmost boundary,” near the Garden of Abode.14PubMed Central. The ethnobotany of Christ’s Thorn Jujube (Ziziphus spina-christi) in Israel Another describes the faithful in paradise among “thornless lote-trees” with shade, water, and plentiful fruit.15PubMed Central.

Eating the Fruit and What It Contains
The fruit, known in many countries as nabq or nabaq, is eaten fresh or dried. It is small and round, and ripe ones taste sweet with a mild tartness, somewhat like a small apple or a date. The flesh is thin and surrounds a hard stone, so you eat around it and spit it out. Fresh fruit is sold in markets during its season, and drying lets people keep it for months. Dried fruit tastes sweeter and chewier, because the sugars are more concentrated.
Its dried flesh is about 80% carbohydrate, mostly starch and sugars like sucrose, fructose, and glucose.17International Journal of Pharmaceutical Research and Applications. Medicinal Value of ziziphus Spina Christi 100 g of dried pulp gives about 314 calories with under 5 g protein and under 1 g fat.18International Journal of Pharmaceutical Research and Applications.

Sidr Honey and Why It Costs So Much
Sidr honey comes from bees feeding mostly on Christ’s thorn flowers. In tested Libyan sidr honey, 60 to 67% of the pollen came from this tree.23Libyan Journal of Medical Research. Sidr Ziziphus spina-christi Honey Quality Across Western Libya: A Preliminary Physicochemical and Pollen-Based Study Its moisture and other qualities vary by region.24Libyan Journal of Medical Research. Sidr Ziziphus spina-christi Honey Quality Across Western Libya: A Preliminary Physicochemical and Pollen-Based Study
Sidr honey is one of the rarest and most expensive single-flower honeys in the world.25Food Bioscience. Sidr honey: A comprehensive review of its nutritional value, biological impact, and potential health benefits A kilogram of Yemeni sidr honey can cost up to about $200.26Food Bioscience. Sidr honey: A comprehensive review of its nutritional value, biological impact, and potential health benefits Producers also face problems like poor beekeeper training, old methods, and loss of wild trees.27Food Bioscience. Sidr honey: A comprehensive review of its nutritional value, biological impact, and potential health benefits
High prices invite fakes, including cheap honey blended with other honeys or syrup and sold as pure sidr. Look for sellers who state the origin and can show laboratory test results for the batch. Pollen analysis under a microscope is a standard way to check that a honey really comes mostly from this tree. A very low price for “Yemeni sidr” is a warning sign, given how costly the genuine product is.
Traditional Medicine Uses
Ancient Egyptian prescriptions used the tree for pain, swelling, and heat.28PubMed Central. Genus Ziziphus for the treatment of chronic inflammatory diseases Today almost all parts are used in folk medicine.29Ecology & Conservation Science: Open Access. Evaluation of the Benefits Of Christ-Thorn Jujube Zizphus Spina-Christi l. Desf Tree in Nigeria Uses include asthma, dandruff, eye problems, fever, pain, ulcers, wounds, and inflammation.30Ecology & Conservation Science: Open Access. Evaluation of the Benefits Of Christ-Thorn Jujube Zizphus Spina-Christi l. Desf Tree in Nigeria Medicinal uses in Israel match those across the Middle East, with no group holding special uses.31PubMed Central. The ethnobotany of Christ’s Thorn Jujube (Ziziphus spina-christi) in Israel
Many people meet the plant through its leaves. Dried leaves are ground to a powder and mixed with water to make a paste or wash for hair and scalp, which fits the traditional dandruff use. The powder is sold in markets and online as a natural shampoo. In Muslim tradition, sidr leaves are also added to the water used for washing the body of the dead. Long use shows people valued the tree, not that it cures disease.
What Science Says About Its Medicinal Effects
Bark extracts stopped the growth of several bacteria and a fungus in lab dishes.32PubMed Central. Phytochemical Screening and Antimicrobial Activity of Ziziphus spina-christi Stem Barks Other bark extracts acted against bacteria like E. coli and against colon and breast cancer cells in the lab.33Biomedical Research (India). Phytochemical, antimicrobial and cytotoxic evaluation of Ziziphus spina-christi (L.) stem bark The leaves contain soap-like compounds that harmed cancer cells in lab tests.34PubMed Central. New cytotoxic dammarane type saponins from Ziziphus spina-christi Killing cells in a dish is far from treating infection or cancer in a person.
Animal studies point the same way. Fruit extract eased gut inflammation in rats with induced colitis.35PubMed Central. Genus Ziziphus for the treatment of chronic inflammatory diseases Its plant compounds lowered high cholesterol in animals.36PubMed Central. Genus Ziziphus for the treatment of chronic inflammatory diseases Leaf extract protected rats’ kidneys from mercury damage.37PubMed Central. Ziziphus spina-christi Leaf Extract Suppressed Mercury Chloride-Induced Nephrotoxicity via Nrf2-Antioxidant Pathway Activation and Inhibition of Inflammatory and Apoptotic Signaling
Lab studies often use extracts far more concentrated than anything you would get from eating the fruit or drinking a tea. A compound that works on cells in a dish may be poorly absorbed or broken down in the body before it reaches the target. Human trials have not been done for these uses.
Using the tree instead of antibiotics or cancer care could be dangerous. Talk with a doctor before using herbal extracts alongside medicines.
Is It Safe to Eat or Use
People have eaten the fruit for generations in its native regions. High doses of fruit extract, though, changed liver and kidney test results and damaged these organs in rats.38Public Health Toxicology. Toxicity evaluation of Ziziphus spina-christi fruit on Wistar rats Concentrated extracts or large supplement doses therefore carry more risk than eating the fruit, which packs far less of the plant’s compounds into each serving.
The rat findings involved high doses, so they don’t show that normal eating of the fruit harms people. They are a reason for caution with supplements. Stick to food amounts and check with a doctor before taking extracts, especially with liver or kidney problems, pregnancy, or regular medicines.
Supplements are not tested like medicines, so strength varies. Avoid products claiming to cure serious disease, and stop and seek care if you notice yellowing skin or dark urine.
Growing Christ’s Thorn From Seed
The seeds have a hard coat that slows sprouting. Roughening the coat with sandpaper or soaking in strong acid improves sprouting.39مجلة سوهاج لشباب الباحثين. Effects of sulfuric acid and mechanical method by using sandpaper on the germination of Christ’s thorn Zizphus spina-christi (L.) Desf. seeds Strong acid is dangerous, so home growers should use sandpaper or a file instead.
The tree does best in hot, sunny, dry places and tolerates poor soil, so it suits gardens in warm dry climates. It dislikes frost and waterlogged ground, and soggy soil or hard freezes will often kill it. The thorns make it a natural barrier hedge, but it should be planted away from paths and play areas. Check whether it is listed as a restricted weed in your area, as it is in parts of Australia, before planting.
