Camelthorn or Persian manna plant (Alhagi maurorum) is a deep-rooted thorny perennial in the pea family, Fabaceae. It is native across a broad belt from western and Central Asia into parts of South Asia and has also become established outside its native range.
The plant is known by several regional names, including khar shotor, jawasa and yantak. In Persian and neighboring traditions it is closely associated with taranjabin, a sweet manna-like material collected from the plant.
Camelthorn has a long traditional reputation as a diuretic, digestive herb, laxative or purgative, expectorant and urinary-stone herb. Modern research has identified flavonoids, phenolic acids and other active constituents and has explored the plant in laboratory, animal and limited human studies.
Materia Medica
Botanical name: Alhagi maurorum
Family: Fabaceae
Common names: camelthorn, camel thorn, Persian manna plant, jawasa, yantak, khar shotor
Older botanical name: Hedysarum alhagi
An important modern distinction is that Alhagi maurorum and Alhagi pseudalhagi are treated as separate species. Older herbal, weed-management and pharmacology literature sometimes blurred those names together, so research should be matched to the species actually studied rather than automatically transferred across the genus.
Actions & Energetics
Traditional Western and Persian uses: diuretic, expectorant, gentle laxative or purgative, diaphoretic and topical herb in different preparations. Sweet taranjabin manna was traditionally characterized as a mild aperient and moistening substance. Regional hot/cold energetic classifications vary with the part or formula; no single energetic label should erase those differences.
Botanical Description
Alhagi maurorum is native across dry regions stretching through western and Central Asia into parts of northern South Asia. It tolerates heat, drought, salinity and disturbed soils but can also flourish where its extensive root system can reach reliable moisture.
Once established, the plant can be extremely difficult to remove. Its deep, spreading underground system can send up new shoots well away from the original crown, and root fragments left after cultivation or digging may resprout.
Identification
- gray-green branching stems;
- small alternate leaves;
- sharp spines arising near the leaf axils;
- small pink, reddish or maroon pea-like flowers;
- narrow pods that may look constricted between the seeds;
- a strong, spreading root system capable of producing new shoots.
Name Confusion & Look-Alikes
Alhagi maurorum is a specific Fabaceae species; botanical and older medicinal literature also uses names including Alhagi camelorum in older taxonomic contexts, and some materia medica references use names for distinct Alhagi taxa. The vernacular name taranjabin is recorded from more than one accepted Alhagi species. A marketplace name alone is not proof that the manna or dried herb comes from A. maurorum.
Taranjabin: Persian Manna
Camelthorn is famous for its association with taranjabin, sometimes called Persian manna. Historical Persian and Islamic materia medica describe this sweet substance as a mild laxative, soothing material and medicinal sweetener.
Taranjabin is not simply ordinary plant sap. Much of the material collected from Alhagi is now understood to develop through the activity of sap-feeding insects, which deposit a sugary secretion onto the aerial parts of the plant. The material then dries or crystallizes on the surface.
Because of that, camelthorn herb and taranjabin are not the same preparation. The aerial herb, root, distilled preparations, extracts and manna should be kept distinct when discussing traditional use or modern research.
Historical Taranjabin Use
Traditional uses of taranjabin have included:
- mild laxative and aperient preparations;
- soothing preparations for cough or throat irritation;
- use during feverish states and thirst;
- sweetening more bitter medicinal preparations.
These uses belong to historical materia medica and should not be mistaken for proof of a modern clinical treatment.
Traditional Indications
Across regional herbal traditions, camelthorn has been used as a:
- diuretic;
- laxative or purgative;
- diaphoretic;
- expectorant;
- digestive and abdominal remedy;
- traditional urinary-stone herb;
- remedy for rheumatic complaints;
- topical plant in some skin and wound traditions.
Preparations & Dosage
Historical and regional herbal practice includes several different preparation styles:
- Aerial-part decoction: leaves and stems simmered or boiled in water and strained.
- Root decoction: roots simmered in water in some urinary and topical traditions.
- Hydrosol or distilled preparation: camelthorn distillates are used traditionally in parts of Iran.
- Taranjabin soak: the sweet manna material is dissolved or soaked in water before use.
These describe traditional practices rather than one standardized modern formula. Plant identity, plant part, concentration and extraction method can change the chemistry substantially.
Dried Aerial Herb: Cut & Sifted and Powder
Air-dried leaves and thorny young aerial shoots are historically employed in some regional herbal preparations. Cut-and-sifted herb is intended for straining; powder is a different presentation that can carry more fine plant particles. No validated general adult medicinal daily dose of powdered A. maurorum is established by the limited modern human research.
Decoction or Herbal Infusion — Historical Method
Traditional regional preparations include briefly boiled roots or aerial parts, then straining from the water. A covered hot-water infusion extracts a different fraction from a longer root or stem decoction; there is no universal established treatment dose for either. Comparisons must specify the dry herb weight, plant part and actual volume of finished liquid.
Manna / Taranjabin Solution and Syrup
Historical descriptions explain that hardened manna granules were collected from the plant and cleaned, sometimes dissolved in water and separated from thorns and leaf impurities by straining. A concentrated, sweet manna solution or syrup belongs to food and regional classical practice; it is not equivalent to alcohol tinctures or a concentrated aqueous herb extract. Historical Persian quantities cannot be assumed modern clinical doses.
Modern Tincture — Dried Herb 1:5
A technical contemporary herbal tincture uses one part weighed dried aerial herb by weight to five parts finished tincture by volume, typically with 40–60% ethanol and a 2–4-week covered maceration followed by pressing and fine filtration. This describes an extraction method only; there is no validated clinical adult dosage for a generic 1:5 camelthorn tincture, and it must not be substituted for extracts tested in kidney-stone trials.
Liquid Extract — 1:2
A 1:2 extract represents approximately one part dry herbal starting material to two parts liquid extract by volume, with solvent and manufacturing process stated separately. Species, plant part, solvent and alkaloid/flavonoid recovery determine finished chemistry; the ratio is not a reason to invent a patient dosage.
Fresh Herb, Oil, Wash and Poultice
Fresh plants have regional fodder and craft histories, but fresh expressed juice is not an established standardized clinical preparation of A. maurorum. Historical topical leaf oil or wash uses are recorded in ethnobotanical compilations; concentrated topical oils and immediate-use fresh poultices do not share a verified official strength or clinical dose.
Classical Formulations
Persian and related traditional sources name taranjabin as an ingredient or sweetening adjunct in medicinal drinks and purgative combinations. Historical descriptions emphasize a sweet exudate dissolved, filtered and consumed in regional formulas, rather than a single worldwide standardized recipe. An Ayurvedic Brahmi Ghrita formula does not belong to this species.
Constituents
Camelthorn contains a wide variety of plant compounds, including:
- flavonoids, including quercetin- and isorhamnetin-related compounds;
- phenolic acids;
- sterols and triterpenoid-related compounds;
- polysaccharides and other water-soluble constituents;
- additional secondary metabolites whose amounts differ by plant part and extraction method.
Leaves, flowers and roots do not necessarily contain the same proportions of these compounds, which is one reason results from a root extract cannot simply be assigned to a leaf tea or taranjabin.
Modern Research
Antioxidant Research
Leaf, flower and root extracts have shown antioxidant activity in laboratory testing. Phenolic fractions from the root have also demonstrated antiplatelet activity in vitro.
These findings help explain the plant’s chemistry, but they do not establish that drinking camelthorn decoction prevents chronic disease or produces the same effect inside the human body.
Digestive Research
Animal studies have examined camelthorn extracts in models of diarrhea and gastric irritation. Some extracts reduced experimentally induced diarrhea and showed gastroprotective activity in those models.
That gives preclinical support to some of the traditional digestive uses, but it is not the same as demonstrating a proven treatment for human diarrhea, ulcer disease or inflammatory bowel disorders.
Urinary-Stone Tradition
Camelthorn has one of its strongest traditional reputations in urinary and kidney-stone practice. Root preparations, hydrosols and aerial-part preparations have historically been used to encourage urination and support stone passage.
Laboratory work has also found ureter-relaxing and diuretic effects from some extracts, providing a plausible mechanism for part of that traditional reputation.
Human Kidney-Stone Research
A small randomized prospective human study published in 2023 followed 80 adults with kidney or upper-ureter stones measuring approximately 4–10 mm. A defined hydroalcoholic aerial-part extract of Alhagi maurorum was compared with hydrochlorothiazide.
Both groups showed reductions in stone size and number, with the camelthorn preparation producing promising results and no major complications reported in that study.
This is meaningful because it moves beyond test-tube and animal work, but it is still a small body of human evidence. It does not establish a universal camelthorn dose or make the herb equivalent to standard medical treatment. Larger independent trials are still needed.
Metabolic Research
Animal and laboratory studies have explored camelthorn in glucose regulation, lipid metabolism and digestive-enzyme activity. Some extracts have lowered glucose or lipid measures in experimental models, and laboratory work has shown activity against enzymes involved in carbohydrate and fat digestion.
These findings are preliminary. They should not be presented as evidence that camelthorn can replace established diabetes or lipid-management treatment.
Liver and Kidney Research
Animal research has examined camelthorn extracts in models of drug-related liver and kidney stress. Some studies reported improvements in oxidative-stress markers and tissue findings.
That type of research investigates possible protective mechanisms. It does not mean camelthorn should be routinely combined with prescription medication to prevent side effects.
Human Evidence Overall
Human research on Alhagi maurorum remains limited. The strongest body of information still comes from traditional use, chemistry, laboratory assays and animal studies, with a smaller emerging clinical literature focused mainly on urinary stones.
That makes camelthorn an interesting research herb, but not one with a fully established modern dosing or long-term safety standard.
Adverse Effects
Modern human safety information is limited, and preparation matters. Important considerations include:
- Diuretic activity: concentrated preparations may influence fluid and electrolyte handling.
- Blood pressure and heart rate: cardiovascular effects have appeared in animal pharmacology.
- Platelet activity: root fractions have shown antiplatelet effects in laboratory testing.
- Blood glucose: experimental metabolic activity means concentrated use should not automatically be considered inert alongside glucose-lowering medication.
- Species substitution: findings from A. pseudalhagi or another Alhagi species should not automatically be transferred to A. maurorum.
Interactions & Contraindications
Reported diuretic and purgative effects make hydration and electrolyte effects relevant for highly concentrated products, but published human trials do not establish a universal, clinically proven prescription-drug interaction list. Documented susceptibility to the plant and the possibility of delayed kidney-stone treatment are stronger, more immediate considerations than speculative enzyme interaction claims.
Pregnancy & Breastfeeding
Reliable modern pregnancy and breastfeeding safety data for medicinal-strength camelthorn preparations are lacking. Historical use alone cannot establish reproductive safety, especially for concentrated extracts or repeated internal dosing.
Children — Traditional Reports and Clinical Data
There is no dependable modern pediatric dosing standard for Alhagi maurorum. Regional traditional use of taranjabin should not be converted into a generalized child dose without better safety data.
Kidney Stones Require Context
The existence of promising human research does not make every urinary stone appropriate for home treatment. Stone size, location, obstruction, infection and kidney function all change the risk.
Fever, chills, inability to urinate, uncontrolled pain, repeated vomiting, one functioning kidney or signs of urinary obstruction require prompt medical evaluation.
Habitat & Cultivation
Kew identifies this as a perennial or subshrub native from parts of southeastern European Russia and Central Asia to northern India, now introduced to parts of the western United States. Plants for a Future lists USDA hardiness zones 6–10 for suitable conditions. This is not a general recommendation to cultivate it: extensive creeping underground roots and established weed impacts can outweigh any horticultural interest.
Invasive Behavior
Camelthorn is not simply a garden herb. In parts of the western United States it behaves as an aggressive invasive plant because of its extensive creeping roots and ability to regenerate from underground material.
It can spread through agricultural land, rangeland, irrigation corridors and disturbed desert or riparian habitats. Once established, repeated cutting alone may not eliminate the root system.
United States Regulation
Camelthorn is not currently included on the federal noxious-weed list, but state and local rules can be stricter. Several western states regulate or actively manage it as an invasive or noxious plant.
Live plants, roots or seed therefore deserve a regulation check before they are purchased, shipped or planted.
Illinois Status
Alhagi maurorum is not currently included on Illinois’ official Exotic Weeds list. That does not change its aggressive behavior elsewhere or guarantee that future local or state rules will remain the same.
Growing Considerations
Where cultivation is legal, camelthorn deserves more caution than an ordinary culinary herb. Its underground system can spread widely and become difficult to contain. A medicinal or historical interest in the plant does not outweigh local invasive-plant restrictions.
Propagation
Camelthorn spreads by deeply rooted, creeping underground stems and by seed. Tiny remaining root fragments may regenerate, complicating eradication where it is invasive. Botanical sourcing for educational use does not require establishing living plants in regions where their spread would harm agriculture or natural habitats.
Harvesting & Drying
Historical reports describe the late-season collection of hardened manna from aerial branches, with debris removed and the sweet material kept dry. Dried aerial parts, roots and exudates are harvested and processed as different raw materials; branch thorns and soil contamination require special attention. Finished specimens should be dry, labeled with species, source region and plant part, and protected from moisture.
Food Use
Sweet manna is a traditional regional food-ingredient and medicinal adjunct, separate from the thorny aerial herb or deep root. The production and quantity of manna vary with location and climate; not every stand produces it. Historical cooked root is documented as a rare emergency food, not an ordinary vegetable.
History, Folklore & Spiritual Use
Persian and wider Islamic materia medica retain a rich record of taranjabin, its collection and medicinal role. Historic authors debated its relationship to scriptural manna, but identification with the Biblical manna is not established. These cultural associations deserve to be presented as traditions rather than certain botanical identifications.
Sourcing Dried Herb
For dried herbal material or extracts, look for:
- the full botanical name Alhagi maurorum;
- the stated plant part—root, aerial herb, leaves or manna;
- country or region of origin;
- identity and contaminant testing;
- clear distinction between ordinary herb, hydrosol, extract and taranjabin;
- no silent substitution of A. pseudalhagi.
Materia Medica Summary
Camelthorn or Persian manna plant is a chemically active Fabaceae herb with a long medicinal and food-history footprint across western, Central and South Asia. Traditional uses include diuretic, digestive, laxative, expectorant and urinary-stone applications, while taranjabin has its own history as a sweet, soothing and mildly laxative material.
Modern research confirms flavonoid- and phenolic-rich chemistry and reports gastrointestinal, metabolic, antioxidant, ureter-relaxing and other activities in laboratory and animal models. A small human kidney-stone study adds promising clinical evidence, but larger independent trials are still needed.
Taxonomy and ecology matter as much as pharmacology. A. maurorum should not automatically be treated as identical to A. pseudalhagi, and the plant’s invasive root system makes live cultivation inappropriate in some regions.
