  • Rosa nitida Willd. Rosaceae. Shining rose. Distribution: North-eastern North America. Nitida is Latin for shining, referring to the shiny leaves. The seed heads contain vitamin C. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Solanum atropurpureum Schrank Solanaceae. Purple Devil. Purple-spined Nightshade. Herbaceous perennial. Distribution: Brazil. This ferociously spined plant contains tropane alkaloids, atropine, hyoscyamine and scopolamine. All are anticholinergic and block the acetylcholine mediated actions of the parasympathetic nervous system. While the alkaloids are used in medicine and as an antidote to anticholinergic nerve gas poisons, the plant itself is not used in medicine. Its sharp spines can be irritant. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Hedge mustard pollen
  • Agrimonia eupatoria L. Agrimony, Eupatorium, Maudlein. Perennial herb. The species name comes from king Mithridates Eupator VI of Pontus (132-63 BC) who took regular doses of poison to develop an immunity to them. A 'Mithridate' was a medicine against poisons. Distribution: N. and S. Africa, N. Asia, Europe. '…provokes urine and the terms [periods], dries the brain, opens stoppings, helps the green sickness [iron deficiency anaemia], and profits such as have a cold weak liver outwardly applied it takes away the hardness of the matrix [=uterus] and fills hollow ulcers with flesh' (Culpeper, 1650). Dioscorides (Beck, 2005) recommends mashed leaves in hog's grease for healing scarring ulcers, and the seed in wine for dysentery and serpent bites. Goodyear's 1655 translation of Dioscorides (Gunther 2000) has this as cannabis, which Parkinson (1640) says is in error and summarises the manifold uses from classical authors, from removing splinters to stopping menorrhagia. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Rudbeckia triloba L. Asteraceae Orange Cone flower. Herbaceous perennial. Distribution: North America. It is named for Olof Rudbeck, father (1630–1702) and son (1660–1740). Olof Rudbeck the Elder was professor of medicine at Uppsala University, and established a botanic garden there. He was the discoverer of the human lymphatic system. His son succeeded his father as professor of medicine, and one of his students was Carl Linnaeus (1707–88) who named the genus Rudbeckia after him and his father. It is a plant which is poisonous to cattle, sheep and pigs with no medicinal uses. Austin (1974) discusses R. hirta, also regarded as a toxic plant. It was used externally by the Cherokee to bathe sores and snakebites and made into a tea for treating diarrhoea. The Seminoles used it for headaches and fever and the Miccosukee for sunstroke and headache. The Cherokee and the Iroquois used it to treat intestinal worms Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Geranium maderense Yeo Geraniaceae Tender evergreen biennial. Madeira cranesbill. Distribution: Madeira. Solely grown for its spectacular flowers. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Acanthus dioscoridis L. Acanthaceae. Distribution: Iran, Iraq, southern Turkey. Herbaceous perennial flowering plant. Named for Pedanius Dioscorides of Anazarbus, 1st century Greek physician and herbalist whose book, De Materia Medica, was the main source of herbal medicinal information for the next 1,600 years. He describes some 500 plants and their medicinal properties. His manuscript was copied and annotated over the centuries, and the earliest Greek text in existence is the illustrated Juliana Anicia Codex dated 512CE (Beck, 2005). The first English translation was made around 1650 by John Goodyear and published by Robert T. Gunther in 1934
  • Tiger Lily
  • Papaver rhoeas L. Papaveraceae Corn Poppy, Flanders Poppy. Distribution: Temperate Old World. Dioscorides (Gunther, 1959) recommended five or six seed heads in wine to get a good night's sleep the leaves and seeds applied as a poultice to heal inflammation, and the decoction sprinkled on was soporiferous. Culpeper (1650) ' ... Syrup of Red, or Erratick Poppies: by many called Corn-Roses. ... Some are of the opinion that these Poppies are the coldest of all other - believe them that list [wishes to]: I know no danger in this syrup, so it be taken in moderation and bread immoderately taken hurts
  • Tanacetum Parthenium (Feverfew)
  • Alnus glutinosa (Common Alder)
  • Viburnum japonicum Spreng. Caprifoliaceae Evergreen Shrub. Distribution: Japan and Taiwan. No medicinal uses. The fruit is a 'famine food' eaten when all else fails. As other seeds/fruits of Viburnum species are listed as poisonous, and none are listed as 'edible', one can assume that the seeds/fruits of V. japonicum are also toxic. It does not appear vulnerable to pests or molluscs which may be due to irioid glycosides that are present in this genus produced as a defence against herbivores, fungi and bacteria. They have a bitter taste. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Tragopogon pratensis L. Asteraceae. Goatsbeard, Salsify, Jack-go-to-bed-at-noon. Distribution: Europe and North America. This is the Tragopogion luteum or Yellow Goats-beard of Gerard (1633) who recommended them boiled until tender and then buttered as being more delicious than carrots and parsnips and very nutritious for those sick from a long lingering disease. Boiled in wine they were a cure for a 'stitch' in the side. In the USA children collect the milky sap onto a piece of glass and, when dry, chew it as bubble-gum. The name 'Jack-go-to-bed-at-noon' referes to the flowers which close at noon and the spherical radiation of seed plumules which then appear. Salsify is now applied as a name for T. porrifolius and Scorzonera hispanica. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Knautia macedonica Griseb. Dipsacaceae. Distribution: Macedonia. This honours the brothers Knaut, both physicians and botanists: Christof Knaut (also Knauth, 1638–94) and his brother Christian Knaut (1654–1716). The plant was traditionally used as a compress in its native Balkans to relieve dermatitis and itching. This use is a local survival of what was once a widespread application of this plant and its relations, and is an example of the doctrine of signatures in which the therapeutic benefit of a plant is suggested by some aspect of its anatomy
  • Paeonia suffruticosa 'Bai Yu'
  • Verbena bonariensis L. Verbenaceae. Purpletop Verbena. Distribution: South America. Verbena is Latin for the shoots of Laurel
  • Veratrum nigrum L. Melanthiaceae Distribution: Europe. Cows do not eat Veratrum species in the meadows, and human poisoning with it caused vomiting and fainting. In the 1850s it was found to reduce the heart's action and slow the pulse (Bentley, 1861, called it an 'arterial sedative'), and in 1859 it was used orally in a woman who was having convulsions due to eclampsia. Dr Paul DeLacy Baker in Alabama treated her with drops of a tincture of V. viride. She recovered. It was used thereafter, as the first choice of treatment, and, when blood pressure monitoring became possible, it was discovered that it worked by reducing the high blood pressure that occurs in eclampsia. By 1947 death rates were reduced from 30% to 5% by its use at the Boston Lying-in Hospital. It works by dilating the arteries in muscles and in the gastrointestinal circulation. A further use of Veratrum species came to light when it was noted that V. californicum - and other species - if eaten by sheep resulted in foetal malformations, in particular only having one eye. The chemical in the plant that was responsible, cyclopamine, was found to act on certain genetic pathways responsible for stem cell division in the regulation of the development of bilateral symmetry in the embryo/foetus. Synthetic analogues have been developed which act on what have come to be called the 'hedgehog signalling pathways' in stem cell division, and these 'Hedgehog inhibitors' are being introduced into medicine for the treatment of various cancers like chondrosarcoma, myelofibrosis, and advanced basal cell carcinoma. The drugs are saridegib, erismodegib and vismodegib. All the early herbals report on its ability to cause vomiting. As a herbal medicine it is Prescription Only, via a registered dentist or physician (UK Medicines and Healthcare Products Regulatory Agency (MHRA)). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Allium moly L., Alliaceae. Golden garlic. Bulbous herb. Distribution: Southwest Europe and Northwest Africa. This is not the 'moly' of Homer's Odyssey Book 10 lines 302-6 which describes Mercury giving Ulysses 'Moly', the antidote to protect himself against Circe's poison ''... The root was black, while the flower was as white as milk
  • Aucuba japonica 'Rosannie'
  • Punica granatum L. Lythraceae Pomegranate, granatum malum, balustines. Distribution: E. Mediterranean to Himalayas. The Pomegranate is in the centre of the Arms of the Royal College of Physicians, perhaps for its use in cooling, and therefore for fevers. However it was the sour pomegranate that would have been used as Dioscorides says the sweet ones are unfit for use in agues. Culpeper (1650) makes no mention of the fruit, but says of the flowers ‘... they stop fluxes and the Terms in women.’ In the Complete Herbal and English Physician (1826) he says the fruit ‘... has the same general qualities as other acid fruits.’ Of the flowers he says (among other properties) that ‘A strong infusion of these cures ulcers in the mouth and throat, and fastens loose teeth.’ Gerard (1633) says that the cravings of pregnant women can be abolished with the juice, and perhaps it was scurvy which was being treated effectively when he reports that the juice was very effective against splitting of blood and for loose teeth. The dwarf form of this species, Punica granatum var. nana has fruits no more than 3cm across. Pomegranate bark can only be sold by registered pharmacies in the UK and used to be used as a vermifuge, with the secondary use that the tincture made from it doubled as a permanent ink. In South Africa the fruit rind is used for diarrhoea and stomach ache, and the bark as a vermifuge, but undesirable side effects make this dangerous. It is reported to be effective against fevers, as a diuretic, to lower blood sugar and to be both antibacterial and antiviral (van Wyk, 2000).
