  • Origanum vulgare 'Compactum'
  • Glaucium flavum Crantz Papaveraceae Yellow horned poppy. Distribution: North Africa, Western Asia to Europe. Contains glaucine which is toxic but in small doses may be bronchodilator. As Papaver corniculatum luteum it was known to Parkinson (1640) who reports it as bitter, so advises taking it in honey, as a purgative and analgesic
  • Acer japonicum Thunb. Sapindaceae. Japanese maple. Small tree. Distribution: Japan, North Korea. Can be tapped in early spring for its sugar-rich sap although it is not as abundant as in Acer saccharum. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Reseda lutea L. Resedaceae Wild Mignonette. Dyers Rocket. Herbaceous plant. Distribution: Eurasia and North Africa. This plant, and in particular R. luteola, is the source of 'weld' a yellow dye from luteolin a flavonoid in the sap. It is said to have been used since the first millennium BC, but curiously Dioscorides, Lyte, Gerard, Lobel, Fuchs, Coles, Quincy, Linnaeus (1782) either do not mention it or make it synonymous with Eruca, Rocket, and make no reference to it as a dye source. The name Resedo means 'I sit up' in Latin, which Stearn (1994) interprets as 'I heal' which makes its absence even more strange. It is noted as the dye source by Bentley (1861). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Vicia faba L. Fabaceae. Broad beans, Fava bean. Distribution: N. Africa, SW Asia. Culpeper (1650) writes: 'Fabarum. Of Beans. Of Bean Cods (or Pods as we in Sussex call them) being burned, the ashes are a sovereign remedy for aches in the joints, old bruises, gout and sciaticaes.’ The beans are perfectly edible for the majority, but 1% of Caucasians, predominantly among Greeks, Italians and people from the Eastern Mediterranean regions, have a genetic trait in that they lack the ability to produce the enzyme glucose-6-phosphate dehydrogenase. As a consequence, eating broad beans or even inhaling the pollen, causes a severe haemolytic anaemia a few days later. This condition is known as favism. The whole plant, including the beans, contains levodopa, a precursor of dopamine, and some patients with Parkinsonism report symptomatic improvement after commencing on a diet that contains these beans regularly. A case of neuroleptic malignant-like syndrome (fever, rigidity, autonomic instability, altered consciousness, elevated creatine phosphokinase levels) consequent on abrupt discontinuation of a diet containing plenty of broad beans, has been described in a patient with Parkinsonism. This is usually seen when patients abruptly discontinue L-dopa therapy. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Helianthus annuus Greene Asteraceae. Sunflower, Marigold of Peru, Floure of the Sun. Distribution: Peru and Mexico. It was much recommended by Gerard (1633) who advises that the buds, covered in flour, boiled, and eaten with 'butter, vinegar and pepper, far surpass artichokes in procuring bodily lust’. Sadly, today only the seeds of sunflower are consumed, as the source of sunflower seed oil used in cooking. It contains mono and polyunsaturated fats, linoleic acid and oleic acid, and is low in saturated fats. As such it was thought to lower cholesterol and so the risk of heart disease, but it may increase the risk of breast and prostatic cancer. However a recent report BMJ2013
  • Tragopogon pratensis L. Asteraceae Goats beard, 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.
  • Pulmonaria officinalis L. Boraginaceae Distribution: Officinalis indicates its medicinal use in early medicine. Europe. Pulmonaria or Lungwort are names for a lichen and a perennial plant in the Boraginaceae. This is the latter. Lyte (1578) has a woodcut of our plant and also calls it Sage of Jerusalem and says it is of ' no particular use in physicke, but is much used in meates and salads with eggs, as is also Cowslippes and Primroses, whereunto in temperature it is much alike.' He lists and describes the lichen separately. Culpeper (1650) said he found many sorts of lunguewort in perusing Authors ' Pulmonari, arborea and Symphytum maculosum [and the latter is our plant, the others the lichen] and that they 'helpe infirmities of the lungues, as hoarseness, coughs, wheezing, shortnesse of breath etc.' Coles (1657) who espouses the Doctrine of Signatures in a way unrivalled by any other English author, might have been expected to confirm the concept that the mottled leaves looked like the cut surface of a lung which indicates their purpose, but he only mentions the lungwort which is a lichen. However, Porta's beautiful book on the Doctrine, Phytognomica (1588), is clear that the plant called Pulmonaria with hairy leaves like a bugloss, spotted white with purple flowers, commonly called 'cynoglossa' [with a woodcut which could be Pulmonaria officinalis] indicate its use for ulcerated lungs, spitting blood, shortness of breath and asthma equally with the lichen with the same name. Lobel & Pena (1570) call it 'PULMONARIA, masculosa folia Borrago, floribus Primula veris, purpureis [PULMONARIA spotted, Borage-leaved, flowers like Primula veris - Cowslips - purple]' and say that women mix the leaves with a little broth and make it into an omelette for lung disorders and to strengthen the heart. Lobel (1576) calls it Maculosa Pulmonaria and describes a white flowered form with a good woodcut. Gerard (1633) uses the same woodcut as Lobel and calls it Pulmonatia foliis Echii, Buglosse Cowslips with red flowers, and a woodcut of a narrow leaved plant as Pulmonaria masculosa, Spotted Cowslips of Jerusalem with red, blue and purple flowers and says 'the leaves are used among pot-herbes. The roots are aso thought to be good against the infirmities of ulcers of the lungs...'. Quincy (1718) writes: '... it has a glutinous juice ... and heals ulcers and erosions. It is commended in coughs and spitting of blood but is little used either in the Shop or Prescriptions. Not used in modern medicine. It is in the family Boraginaceae whose species are often rich in pyrrolizidine alkaloids that cause liver toxicity and liver cancers, but levels in Pulmonaria officinalis may not be significant.

  • Libertia grandiflora Sweet, Iridaceae. Tukauki, mikoikoi, New Zealand satin flower. Herbaceous perennial. Distribution: New Zealand. Named for Marie Libert, Belgian botanist (1782-1863). No medicinal use. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Bagh-e Babor, view to the west
  • Camellia sasanqua Thunb. Theaceae. Christmas camellia. Camellia commemorates Georg Josef Kamel (1661-1706), Jesuit pharmacist from Moravia (Czech Republic) who worked in the Philippines and sent plants to John Ray in England (Oakeley, 2012) Evergreen shrub. Distribution: Japan and China. Leaves are used in Japan to make tea (normally made from C. sinensis) and the seeds to make the edible tea seed oil. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Tropaeolum cv
  • Capsicum annuum 'Masquerade' Distribution: Central and South America. This ‘domesticated species’ originated from Mexico (although the centre of Capsicum evolution was much earlier and from Bolivia) and includes the bland salad peppers and the hot chilli peppers, of which capsaicin (sometimes called capsicain), from the lining of the inside of the chilli, is the main active ingredient. Chilli comes from the Aztec language of the Nahuatl people. It was reputedly introduced to Europe by Columbus in the mid-15th century, but was cultivated in Mexico since 4,000 BCE and used in cooking since 7,200 BCE. After its introduction to Europe, its cultivation very rapidly became world-wide. It appears first as a description (Bock, 1539) with the name teutschem Pfeffer. The first illustration, as Siliquastrum, appears in Historia Stirpes commentarii insignis (Fuchs, 1542). Fuchs did not realise it came from the Americas, as he identified it as a plant described by Pliny, Dioscorides and Avicenna and gave their uses of it. It appear in Dodoen's Cruydeboeck (1551) and Lyte's translation (1557) with the note that it is 'hot and drie in the third degree.' He recommended it for dressing meat, and noted that it 'warmeth the stomach' and was good for a sore throat, scrofula, and topically got rid of spots. Fuch's had reported these properties as being described by Avicenna, but what that plant was is unknown. Lindley (1838) wrote: 'It is employed in medicine, in combination with Cinchona in intermittent and lethargic affections, and also in atonic gout, dyspepsia accompanied by flatulence, tympanitis, paralysis etc. Its most valuable application appears however to be in cynanche maligna [=severe sore throat, with impending suffocation] and scarlatina maligna [=severe scarlet fever], used either as a gargle or administered internally.' However, its principal use medically has been in pain relief, applied locally for pain from muscle injury to post herpetic neuralgia. Capsaicin acts on the pain and heat sensing neurones to make them trigger the sensation of pain at body temperature. Repeated exposure to capsaicin depletes the neurotransmitter substance P that is used to perceive pain, so the relevant nerves no longer transmit the sensation of pain/heat from any cause. It is a banned substance in the equestrian events at the Olympics because of its ability to stop perception of pain. Capsaicin has been shown, experimentally, to kill cancer cells by attacking their mitochondria. Particular interest has concentrated on its ability to reduce the size of tumours of the pancreas and prostate. Various cultivars are used in cooking, and the strength (i.e. how hot they are) is measured in Scoville units. A standard chilli pepper used in England would be around 5,000 Scovilles, the hottest peppers are rated over one million Scoville units.

  • Platanus orientalis subsp insularis
  • Gloriosa superba L. Colchicaceae Gloriosa lily. Gloriosa rothschildiana is now a synonym. Climbing plant. Distribution: Southern Africa to Asia. National flower of Zimbabwe, state flower of Tamil Nadu. Contains colchicine which is poisonous, teratogenic and used for treating gout, Familial Mediterranean fever and Behcet's disease. Its toxicity limits its use as a anti-cancer agent. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Mahonia aquifolium 'Smaragd'
  • Succisia pratensis Greene Asteraceae. Devil’s Bit Scabious, Blue Buttons. Distribution: Europe, W Asia, Africa. Culpeper (1650), under ‘Herbs’ he writes: ‘Succisa, Morsus diobolo, Devil’s Bit. Inwardly taken it easeth the fits of the mother [probably uterine spasm or pain], and breaks wind, taketh away the swellings in the mouth, and slimy phlegm that sticks to the jaws, neither is there a more present remedy in the world, for those cold swellings of the neck, which the vulgar call the Almonds [lymph nodes] of the neck than this herb bruised and applied to them. Folk lore attribute it as a cure-all which was so successful that the Devil bit off the bottom of the roots when he saw it growing down into Hades. However, the roots show no sign of such damage to support the myth. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Hypericum olympicum L. Clusiaceae. Mount Olympus St John's wort. Deciduous perennial herb. Distribution Greece, Asia minor. This is not the plant used for mood disturbances in herbal medicine which is Hypericum perforatum. However, all the 370 species of Hypericum are called 'St John's Wort' so a potential for confusion exists. It shares some of the chemicals thought to be active in Hypericum perforatum. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Trifolium rubens L. Leguminosae. [Note the Family Leguminosae is preferred over Family Fabaceae as the former allows all the legumes to be in one Family and not three - one Family being the current consensus among botanists]. Red Feather Clover. Distribution: Europe. The white clover, Trifolium repens, is listed as a treatment for arthritis by Linnaeus (1782). This and Trifolium pratense, Red Clover, are the ones most used for pastures. All the clovers have root nodules which fix nitrogen from the air into the soil so have an important role in ensuring soil fertility. Trifolium rubens has the same nitrogen fixing ability, and is used as an ornamental garden plant where it still acts to improve fertility. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Scadoxus multiflorus Raf. Amaryllidaceae. Blood Flower, Poison root, Fireball Lily. Distribution: Sub-Saharan Africa. The genus name is a concatenation of the Greek words, Sciadion meaning a parasol or umbel, and doxa meaning 'glorious'
  • Lavatera olbia 'Pink Frills'
  • Valeriana pyrenaica L. Valerianaceae Distribution: Pyrenees. It has no medical use. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Nigella sativa L. Ranunculaceae Love-in-the-mist, Black Cumin, Nutmeg flower, Roman Coriander. Distribution: SW Asia. Culpeper (1650) writes: ‘Nigella seeds, boyled in oil, and the forehead anointed with it, ease pains in the head, take away leprosie, itch, scurf, and helps scald-heads, inwardly taken they expel worms, they provoke urine and the terms, help difficulty of breathing: the smoke of them (being burned) drives away serpents and venomous beasts.’ The seeds are used as a spice, but as might be expected as a member of the family Ranunculaceae, the buttercups, the plant contains a highly poisonous glycoside, in this case called melanthin. The amount of toxicity present in spices is clearly insufficient to cause problems when used as such. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Euphorbia characias subsp. wulfenii
  • Malus domestica 'Court Pendu Plat'
  • Mahonia japonica DC. Berberidaceae. Evergreen shrub. Distribution: China, although long cultivated in Japan. Listed as an ingredient in Traditional Chinese Medicines. No European or modern medicinal use. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Leptospermum scoparium 'Red Damask'
  • 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. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Lobelia tupa L Campanulaceae Tabaco del Diablo [Devil's tobacco]. Distribution: Central Chile. Dried leaves are smoked as a hallucinogen by the Mapuchu Indians of Chile. It was also used as a respiratory stimulant. The genus was named after Matthias de L’Obel or Lobel, (1538–1616), Flemish botanist and physician to James I of England, author of the great herbal Plantarum seu Stirpium Historia (1576). Lobeline, a chemical from the plant has nicotine like actions and for a while lobeline was used to help people withdraw from smoking, but was found to be ineffective. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Rohdea japonica Roth Convallariaceae Distribution: Japan. It is a monotypic genus known as omoto in Japan, meaning ‘evergreen’. It is regarded as a symbol of long life and good fortune
