Euphorbia resinifera (Resin spurge) is a species of spurge native to Morocco, where it occurs on the slopes of the Atlas Mountains.[1]
Contents |
[edit] Growth
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, four-angled, with short but sharp pairs of 6 mm spines on the angles, spaced about 1 cm apart up the stem.[1]
[edit] Distribution
It is similar to its relative Euphorbia echinus, which occurs on the Moroccan coast and the Canary Islands.
[edit] Chemical constituents
Euphorbia resinifera contains a high concentration of the toxin resiniferatoxin which is being used as a starting point in the development a novel class of analgesics.[2] Recent research has shown that this toxin exhibits its effects by interacting with TRPV1, a known pain sensing cation channel that also responds to capsaicin, the primary vanilloid compound found in hot peppers.
