Ricinus communis L. Euphorbiaceae Castor oil plant. Palma Christi. Distribution: Mediterranean, E Africa, India. The seeds themselves are pretty, brown, bean-like usually with gold filigree markings on them, and the interior of the seed is the source of castor oil. The outer coat of the seed is the source of the poison ricin, famous (infamous) for the umbrella murder of Georgi Markov on Waterloo Bridge in 1978. The KGB are alleged to have killed Georgi Markov, a dissident Bulgarian journalist, with a pellet containing 0.28mgm of ricin fired into his leg using a specially adapted air gun in an umbrella. While his symptoms were those of ricin poisoning, no ricin was ever found in the pellet that was extracted from his leg. Two seeds, chewed and ingested are said to be fatal, but most people vomit and get rid of the toxin. Ducks are resistant to ricin, and need to ingest more than 80 to be fatal! In Peru the leaves are used as a tea for stomach ache, although they contain small amounts of ricin. It is called Palma Christi in early herbals because of the five pointed leaves, which schematically represent a hand. It is a monotypic genus in the spurge family.

Camassia leichtlinii (Baker)S.Watson Hyacinthaceae. Great Camas, Quamash. The species was named for Maximillian Leichtlin (1831-1910 of Baden , Germany, bulb enthusiast who corresponded with J.G. Baker at Kew. Bulbous herb. Distribution: North America. The bulbs of Camassia species were eaten by the Native Americans, the Nez Perce, after cooking by steaming for a day - which suggests they may be poisonous raw. They gave them to the American explorers, Meriwether Lewis and William Clerk, on their expedition (1804-1806) when they ran out of food. The bulbs of the similar looking 'Death camus', Toxicoscordion venenosum have been fatal when ingested by mistake (RBG Kew on-line). Steroidal saponins, which are precursors in the manufacture of steroids and cytotoxic activity has been detected in the sap of the bulbs.

Adonis vernalis L. Ranunculaceae. Pheasant's eye, the golden flowered spring (or vernal) Adonis, is named in memory of Adonis, the Greek god of plants, who disappeared into the earth in the winter and reappeared in the spring. The flowers were said to have sprung from his blood when he was gored to death by a wild boar, but this plant must have been the blood red Adonis aestivalis, the summer Adonis. Distribution: Eurasia to Spain and Sweden. Gerard (1633) recommends it for renal stone and intestinal colic. Lewis & Elvin Lewis (2003) note it is poisonous, containing cardiac glycosides (adonitoxin, cymarin, K-strophanthin) and flavonoids. The UK Medicines and Healthcare Products Regulatory Agency (MHRA)) bans its use for ingestion 'no dose permitted' but allow it to be prescribed by a herbal practitioner on a one-to-one consultation.

Aconitum carmichaelii Debeaux. Ranunculaceae. Chinese aconite, Chinese wolfsbane, Carmichael's monkshood. Herbaceous perennial. Distribution C. to W. China to N. America. Named for Dr J.R. Carmichael (d. 1877), English physician, plant collector and Protestant missionary from 1862-1877 in Guangdong and Shandong, China initially in Canton. He aided Francis Forbes to collect plants for Kew. Aconitum plants are so poisonous that Theophrastus states that death was the punishment for possessing them. Aconitine is the poison and was used - from Aconitum ferox - in the 'curry murder' in London in 2009. It causes respiratory paralysis, bradycardia (slowing of the pulse), cardiac arrhythmias, tingling, sweating, gastric cramps, diarrhoea and death, both by ingestion and by absorption through the mucous membranes and the skin. Despite this it is widely used in Chinese herbal medicine. It is a restricted herbal medicine which can only be dispensed by a herbal practitioner for external use following a one-to-one consultation, or by prescription from a registered doctor or dentist (UK Medicines and Healthcare Products Regulatory Agency (MHRA)). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
