Derivation of the botanical name:
Retama, the Hebrew word rotem רותם, seems to be the same as the Arabic word retem, and the retama of the Moors. Rotem, retem, or retama in Arabic defines a string tied around the finger as a reminder. An Arab explanation of the definition and the source of the name, is said that rotem designates a ribbon which the Arabs tie before embarking on a journey. If, upon their return they find the ribbon as they left it, they assume from this that their lovers have not been unfaithful, if the oposite is true - it is a sign that she has betrayed him. It is said that the ribbon is tied only onto a rotem (Retama).
The Hebrew name: “rotem” or “rothem” and “r'tamin”, and “ritmah” or “rithmah” (Greek, ραϑμεν) is translated “juniper”, but is a species of broom known as the white broom, Retama raetam.
The name Rithmah—a place along the route of the Exodus (Numbers 33:18-19)—was named for this shrub (rothem).
Retama raetam is a “stem-assimilant, the green stem does much of the photosynthesizing, especially during the dry season. Fruits and flowers provide forage for goats. The stems provide fuel directly and are also converted to charcoal.
It makes up an important part of the fuel supply for Late Bronze and Iron Age copper smelting. Charcoal remains (40% was Retama raetam) were analysed from copper ore smelting at Khirbet en-Nahas, an Iron Age site in the region of Feinan between Wadi Arabah, Aravah (Hebrew: הָעֲרָבָה, HaArava; Arabic: وادي عربة, Wādī ‘Araba) and the highland of Edom. Radiocarbon dates from the charcoal range from the 12th to the 9th century B.C.
Dr. Aref Abu Rabia, Ben-Gurion University, Be'er Sheva, noted that the Bedouins boil the leaves of Retama raetam (‘ratamals’) in water and use the brew to wash wounds and inflammations. Animals are made to drink this brew as a medicine for brucellosis (an infectious disease caused by contact with animals carrying bacteria called Brucella).
At bedouin marriages and other celebrations the bedouins fasten sprigs of green plants, such as the Retama raetam, to the entrance of the tent. Green, the color of live plants, is a symbol of life and vitality.
