'''''Euphorbia resinifera''''' ('''Resin spurge''') is a species of [[Euphorbia|spurge]] native to [[Morocco]], where it occurs on the slopes of the [[Atlas Mountains]].<ref name="rhs">Huxley, A, ed. (1992). ''New RHS Dictionary of Gardening''. ISBN 0-333-47494-5</ref>
It is a [[shrub]] growing to 60 cm tall, forming multi-stemmed cushion-shaped clumps up to 2 m wide. The stems are erect, [[succulent]], superficially like a [[cactus]] (an example of [[convergent evolution]] in a similar semi-desert climate), four-angled, with short but sharp pairs of 6 mm spines on the angles, spaced about 1 cm apart up the stem.<ref name="rhs"/>
It is similar to its relative ''[[Euphorbia echinus]]'', which occurs on the [[Morocco|Moroccan]] coast and the [[Canary Island]]s.
It contains a high concentration of [[resiniferatoxin]] and is being used to develop a novel and powerful class of [[analgesic]]s.<ref>Appendino, G. & Szallasi, A. (1997) Euphorbium: Modern research on its active principle, resiniferatoxin, revives an ancient medicine. [http://dx.doi.org/10.1016/S0024-3205(96)00567-X]</ref>
