Euphorbia smithii S.Carter

This succulent tree is propagated by stem cuttings. Steps to follow: • For stem cutting propagation, use semi-mature cuttings with at least 5 nodes. • Leave cuttings in shade for one day to dry the cutting area. • For better rooting, use cutting hormone, and plant in long root trainer or pots filled with a ratio of 1 peat moss: 3 perlites: 1 compost. • Leave cutting in a cool shaded area and irrigate once every two weeks. • Stem rooting can vary from 19–75 days, with average rooting percentage around 7%.

In Omani studies: Miller & Morris (1988) wrote that: "This tree is common in Dhofar in the wet woodlands and scarps and also occurs, though more rarely, in the drier areas on the fringe of the monsoon-affected zone, where it is a much slighter and scrubbier bush. The tree is uually called [J: hebšínút], and the latex [J: hiόk], or [J: sahaz ehebšínút]. Medicinally, the latex was most important in veterinary medicine, being used to treat the extremely infectious and dreaded skin disease, called locally jerb, a kind of parasitic infestation which affects both goats and camels. The latex of this tree is suitable for treating both kinds of livestock. More than one tree had to be tapped to accumulate sufficient latex to treat a single camel, and it was a whole morning's work to collect enough to treat more than one. When enough had been collected, a Jatropha dhofarica ... or Salvadora persica sapling was pulled up and the club-like root knocked and rubbed on rock until it frayed out to make a sort of stiff brush [J: mubzik] and this was dipped into the container of latex and brushed over the affected parts of the animal, or if it was very badly infected, over its whole body. The paste was left to harden and work, sometimes a second application being necessary on the second day. For goats of course, a much smaller quantity was needed, and a single application usually sufficed. The latex was also used by the herders themselves. A small quantity of the latex was taken folloed by a drink of camels milk as a vermifuge. However, many rejected this as a remedy, saying it was too severe and that the latex could harden into strands and lumps within the stomach and cause worse damage than the worms themselves. The uncooked latex was an effective adhesive, and its viscosity made it useful as a dressing for cleaned wounds and sores. Elderly camels whose udders had grown hard and consequently difficult to milk were treated with an application of the latex on alternative days once well on into their pregnancy, with the result that their udders became once more soft and supple when they had given birth and the paste was allowed to drop off. The latex was also sun-dried, then collected and stored for use as a depilatory, though the latex of E. balsamifera was generally preferred for this onerous task. Cloth soaked in the latex was applied to the udder of a goat whose kid had to be weaned, a process called in [J: fotol], which was very successful, as the latex is exceptionally bitter. The bark of a tiny seedling was taken to treat constipation and stomach ache. In a milch animal with early mastitis, the latex was used in an attempt to prevent a mild case from turning into a severe one which frequently led to total malfunction of the mammary gland of the affected teat, and sometimes even to the end of the productive life of the animal. After the animal had been mated and a fortnight or so before it gave birth, the whole udder as well as around the navel and the coccyx, was painted with the latex (or latex from Ficus vasta or Ficus lutea) until the birth, as a prophylactic treatment. Fresh latex was also put on a pointed boil, or onto a site of infection which had come to a head to hasten its bursting and draw out the pus. 1 For a fracture, the limb was bound with cloths soaked in the latex (over a layer of some sort of grease) and the splints put either side of the broken lim were strapped with similarly treated material. This coating set hard like plaster of Paris. 1 to make a handle for an implement, the latex was smeared on cloths, or for an especially firm and strong handle, onto strips of leather. These, soaked in the latex, were bound round and round the shaft. This was used where strength and reliability were particularly necessary, such as the handles for matchets used for cutting down wood and so on". (Ref. Plants of Dhofar). In addition, Pickering & Patzelt (2008) mentioned that: "Latex used to kill skin parasites in goats and camels". (Ref. Field Guide to the Wild Plants of Oman; 2008). In Oman Plant Red Data Book, Patzelt (2015) stated that: "The latex was used in veterinary medicine". (Ref. Oman Plant Red Data Book; 2015).
