Euphorbia nicaeensis All. Euphorbiaceae. Distribution: North Africa, Southern Europe to Turkey. Root extracts have been shown to have cytotoxic and anti-inflammatory action in experimental situations. Euphorbia species all have toxic sap, and had many names in early literature, eg esula, about which Culpeper (1650) says that '(taken inwardly) are too violent for vulgar use

Euphorbia milii Des Moul. Euphorbiaceae. Crown of Thorns - so called because of its very spiny stems. Distribution: Madagascar. The latex contains a copper-containing amine oxidase, a lectin, lipase, peroxidase, and a diamine oxidase. In vitro the latex is synergistic with ketoconazole against Candida albicans (thrush). All Euphorbia have a toxic white latex, and in Europe this has been used as a folk remedy to treat warts. It can cause skin allergies and the smoke from burning them is toxic. the genus named for Euphorbus (fl. circa 10 BC – 20 AD), the Greek physician to the Berber King Juba II (c. 50 BC – 23 AD) of Numidia, Euphorbia milii is one of the tropical spurges, with fierce, cactus-like spines, grown as a house plant. The sap of spurges is used in folk medicine for treating warts (not very effective), and, historically, as a purgative - the word spurge being derived from the French word for purgation. The sap (probably dried) was administered inside a fig because it is so corrosive that it would otherwise burn the mouth and oesophagus – a technique used today, rather more subtly, with ‘enteric coated’ medications. The sap contains a potential anti-leukaemic chemical, lasiodoplin, and is also used in drainage ditches to kill the snails which carry the parasitic trematode which causes fasciolaris. It does not kill the fish. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
