Glossostemon bruguieri or Dombeya arabica is a species of flowering plant in the family Malvaceae. It is a shrub with thick long tapering dark colored roots with 70–100 cm in length and 5–8 cm in breadth,Purseglove, J. W.

The roots are commonly used in traditional medicine for many nutritional and medicinal values.
Chemical composition
Starch is the main component of the dried peeled roots with 54.5–62.4% (differs according to the climatic region of cultivation) while protein represents 4.5–8.3%, half of which is aspartic acid. Roots contain high amounts of non-starch polysaccharides including dietary fibers, pectin and up to 27% of mucilage.{{citation needed|date=January 2016}}
Calcium, magnesium and iron are the main minerals of the roots. Minor amounts of zinc, manganese and copper have also been found.
Tatakin (4-methoxyisoscutellargin), takakin 8-O-glucoside, takakin 7-O-glucoside, sesamin, chrysophanol, emodin, parietin, bucegin 7-O-glucoside, isoscutellarein, isoscutellarein 7-O-glucoside, methoxsalen, aesculetin, estrone, scopoletin, phytosterols (a mixture of β-sitosterol, stigmasterol and campesterol) and α-amyrin were extracted from G. bruguieri. The so-called moghatin is a biflavone that has been uniquely discovered in moghat.{{citation needed|date=January 2016}}
Seeds contain around 19.5% protein, 5.0% mucilage, arabinose (1.8%) and glucuronic acid (14.6%).{{citation needed|date=January 2016}}
Both roots and seeds contain rhamnose, xylose, mannose and galacturonic acid.{{cite journal |vauthors=Ibrahim N, el-Eraky W, el-Gengaihi S, Shalaby AS |title=Chemical and biological evaluation of proteins and mucilages from roots and seeds of Glossostemon bruguieri Desf.

Use
In traditional medicine, hot drinks prepared from dried peeled root powder are used after delivery as a galactagogue. It is used as well for increasing body weight, as a demulcent agent and for relief of gout pain.Ibn al-Baitar, الجامع لمفردات الأدوية والأغذية (The Book of Medicinal and Nutritional Terms){{page needed|date=January 2016}}
Health and biological effect
Water extract of G. bruguieri roots has reversed induced juvenile osteopenia in Sprague Dawley rats. However, human clinical trials are yet to be done.{{cite journal |vauthors=Ghareeb DA, El-Rashidy FH, El-Mallawany S |title=Imbalanced Diet Deficient in Calcium and Vitamin D- Induced Juvenile Osteopenia in Rats; the Potential Therapeutic Effect of Egyptian Moghat Roots Water Extract (Glossostemon bruguieri) |journal=Iranian Journal of Pharmaceutical Research |volume=13 |issue=2 |pages=623–35 |year=2014 |pmid=25237358 |pmc=4157038 }}
The unsaponifiable part of the plant leaves was reported to have stronger acaricidal activity on both the adult and egg stages of Tetranychus urticae than other botanical parts of the plant.{{cite journal|url=http://www1.montpellier.inra.fr/CBGP/acarologia/export_pdf.php?id=153&typefile=pdf|title=Chemical investigation of the lipoidal matter of Glossostemon bruguieri and the acaricidal activity of its unsaponifiable fraction|author=S.

Others
The Italian pharmacist Antonio Bey Figari has mentioned G. bruguieri in his 1864 book entitled "Studii scientifici sull'Egitto e sue adiacenze, compresa la penisola dell'Arabia Petrea-Scientific study in Egypt and its surroundings, including the peninsula of Arabia Petraea." He mentioned that the plant was coming from Persia to Egypt through the route of Damascus and was prescribed for cachectic patients, tuberculosis, chest diseases, tabes of children and cases of constitutional syphilis. He thought that Moghat was the main ingredient of the preparation "Revalenta arabica", that was being sold in Europe in the 18th century, but his idea was wrong because it was discovered later that the main ingredient of "Revalenta arabica" was merely lentil flour. He stated as well that he himself has observed wonderful results using the plant.{{cite book|url=https://books.google.com/books?id=ZWr9aGvJmk8C&pg=PA389|title=Studi scientifici sull'Egitto e le sue adiacenze compresa la Penisola dell'Arabia Petrea con accompagnamento di carta geografico-geologica del Dott.
