  • Valeriana officinalis L. Valerianaceae Valerianus, Phu, Nardus sylvestris, Setwal. Distribution: Europe. Popular herbalism attributes sedation to Valerian, but this is not mentioned by Coles (1657) or Gerard (1633) or Lobel (1576) or Lyte (1578) or Dioscorides (ex Gunther, 1959) or Fuchs (1553), where he quotes Pliny, Dioscorides and Galen, or Parkinson (1640), or Pomet (1712). The English translation of Tournefort (1719-1730) covers a whole page of the uses of all the different valerians, but never mentions sedation or treating anxiety. Quincy (1718) does not mention it. Because it was used in epilepsy, for which Woodville (1792) says it was useless, Haller, in his Historia stirpium indegenarum Helvetae inchoatae (1768) advocates it for those with irritability of the nervous system, as does Thomson's London Dispensatory (1811) although he lists it as an 'antispasmodic and stimulant' and for inducing menstruation. Lindley (1838) notes (as many did) that the roots smell terrible and that this makes cats excited, and in man, in large doses, induce 'scintillations, agitation and even convulsions' so used in asthenic fever, epilepsy, chorea, hysteria and as an antihelminthic.' Fluckiger & Hanbury (1879) give a wonderful account of the history of its names, but give its use as 'stimulant and antispasmodic' as do Barton & Castle (1877). but by 1936 (Martindale's Extra Pharmacopoeia) its only use was 'Given in hysterical and neurotic conditions as a sedative. Its action has been attributed to its unpleasant smell'. The European Medicines Agency (2006) approves its use as a traditional herbal medicine for mild anxiety and sleeplessness for up to 4 weeks. Despite what is written continuously about its use in ancient Greece and Rome, the only reason for its use has been because it was thought, for a brief while, to be good for epilepsy and therefore might deal with persons of a nervous disposition because of its foul smell. It has been suggested that even its Greek name, 'Phu' came from the expression of disgust which is made when one sniffs an unpleasant odour. For 1,800 years, before the last century, no-one had thought it sedative. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Pulsatilla vulgaris Mill. Ranunculaceae. Pasque flower. Distribution: Europe. Lindley (1838) and Woodville (1790) knew this as Anemone pulsatilla, the common name being Pasque (Easter) Flower. At the end of the 18th century it was recommended for blindness, cataracts, syphilis, strokes and much more, treatments which, as was clear to physicians at the time, were valueless. Gerard (1633) writes: ‘They serve only for the adorning of gardens and garlands, being floures of great beauty’. It is in the buttercup family, Ranunculaceae, all members of which are poisonous. It was recommended, by mouth, for ‘obstinate case of taenia’ (tapeworms). One hopes it was more toxic to the worm than the patient. Flowers with a central disc and radiating florets were regarded as being good for eye complaints under the Doctrine of Signatures. Porta (1588) writes (translated): ‘Argemone [Papaver argemone], and anemone, have flowers of this shape, from this they cure ulcers and cloudiness of the cornea’. There were occupational diseases even before there were words like pneumoconiosis, and Lindley writes that ‘the powder of the root causes itching of the eyes, colic and vomiting, if in pulverising it the operator do not avoid the fine dust which is driven up.’ Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Silphium perfoliatum L. Asteraceae Indian Cup. Distribution: North America. Austin (2004) records that another species, S. compositum, was used by Native Americans to produce a chewing gum from the dried sap of the roots, and Native American medicinal uses for 'Indian Cup' are probably referrable to S. compositum and not S. perfoliatum. Silphium perfoliatum contains enzymes that inhibit trypsin and chymotrypsin which gives it resistance to fungal, bacterial and insect attacks. Male gall wasps (Antisotrophus rufus) alter the chemistry of the plant to enable them to locate females, making it a 'signpost' plant. The gall wasp lays its eggs in the stem of Silphium laciniatum, to provide food for the larva on emergence, and the galls containing a male or a female wasp will cause the plant to give off a different chemical odour. Emerging male wasps can search for female wasps, which emerge later, by locating this chemical fragrance which acts as a sex pheromone proxy (Tooker et al Proc Natl Acad Sci U S A. 2002 Nov 26
  • Opuntia humifusa Raf. Cactaceae Eastern prickly pear, Indian fig. Distribution: Eastern North America. Stearns (1801) reports 'OPUNTIA a species of cactus. The fruit is called the prickly pear. If eaten it turns the urine and milk in women's breast red'. This is likely to be Opuntia robusta. The ripe fruits are reported edible, raw, and the leaf pads also, either raw or cooked. The fine spines, glochids, cause severe skin irritation so should be wiped off or burnt off prior to cooking and eating. Moerman (1998) reports that O. hemifusa was widely used by Native American tribes for wounds, burns, snakebite, warts (fruit), and as a mordant for dyes used on leather. Widely used, with the spines removed, as a famine food, and dried for winter use. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Felicia amelloides 'Astrid Thomas'
  • Myrtus communis L. Myrtaceae Myrtle Distribution: Europe. Dioscorides (Beck, 2005) recommends the fruit for treating haemoptysis (‘spitting blood’) and cystitis, and, if boiled, he said it made a fine wine. In various forms it was used as a hair dye, for sore eyes, anal and uterine prolapse, dandruff and shingles, all sorts of inflammations, scorpion bites and even sweaty armpits. Our plant has white berries, but he regarded those with black berries (they become black later in the season) as being more effective. Lyte (1576) adds that the juice of the berries kept the hair black and stopped it falling out, and prevented intoxication. He notes that it only flowered in hot summers in England, but it is reliable in flower now, either due to global warming or selection of suitable clones. According to Lyte, it is named after Merlyne, a fair maiden of Athens in ancient Greece, who judged the athletic games. Slain by a disgruntled competitor, the goddess Minerva brought her back as the myrtle tree in perpetual memory. The myrtle tree is also an ancient Jewish symbol for peace and justice. Myrtle wine is still made in Tuscany and now even in China. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Viburnum x bodnantense 'Dawn'
  • Trillium sessile L. Trilliaceae Distribution: North America. Various Trilliums were used by Native Americans to stop haematuria, haematemesis, menorrhagia, and to heal ulcers (Milspaugh, 1974). Roots were eaten to treat stiff muscles, and tea from the plant drunk and powdered plant put on joints for rheumatism by the Iroquois (Lewis & Elvin-Lewis, 2003). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Pulmonaria officinalis L. Boraginaceae Distribution: 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.

  • Rosa gallica L. Rosaceae Distribution: S & C Europe, Western Asia. Culpeper: “Red roses cool, bind, strengthen both vital and animal virtue, restores such as are in consumptions, strengthen. Notes: Rose water and distilled oil of roses have been used in herbal medicine for over a thousand years, and are still used in aromatherapy.

  • Daffodils (Narcissus), x-ray
  • Eranthis hyemalis Salisb. Ranunculaceae Winter Aconite Distribution: Europe. The reason it was called Winter aconite and linked to Aconitum napellus as being just as poisonous is because plants were classified according to leaf shape in the 16th century. L'Obel's 'Stirpium adversaria nova' published in 1571 and 'Plantarum seu stirpium historia' published 1576 (with a full page illustration on page 384 showing Eranthis and Aconitum together) along with the knowledge that related plants have similar medical properties caused the belief that Eranthis are as poisonous as Aconitum. They are both in Ranunculaceae and while Eranthis (like all Ranunculaceae) is toxic if eaten, it does not contain the same chemicals as Aconitum. Caesalpino (Ekphrasis, 1616) pointed out the error in classifying according to leaf shape and recommended flower shape. It contains pharmacologically interesting chemicals such as khellin, also present in Ammi visnaga. This is a vasodilator but quite toxic, which can be converted into khellin analogues such as sodium cromoglicate – used as a prophylaxis against asthma attacks – and amiodarone which has anti-arrhythmia actions so is used for atrial fibrillation and other arrhythmias. It is endangered and protected in the wild (Croatia) because of over-collecting for horticulture. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Cynara cardunculus L. Asteraceae. Cardoon, Globe Artichoke, Artechokes, Scolymos cinara, Cynara, Cinara. Distribution: Southern Europe and North Africa. Lyte (1576) writes that Dodoens (1552) could find no medical use for them and Galen (c.200 AD) said they were indigestible unless cooked. However he relates that other authors recommend that if the flower heads are soaked in strong wine, they 'provoke urine and stir up lust in the body.' More prosaically, the roots boiled in wine and drunk it cause the urine to be 'stinking' and so cures smelly armpits. He adds that it strengthens the stomach so causing women to conceive Male children. He goes on to say that the young shoots boiled in broth also stir up lust in men and women, and more besides. Lyte (1576) was translating, I think with elaborations, from the chapter on Scolymos cinara, Artichaut, in Dodoen's Croydeboeck (1552) as L'Ecluse's French translation (1575) does not mention these latter uses, but Dodoen's own Latin translation, the Pemptades(1583), and Gerard's (1633) both do so. It is useful in understanding the history of these translations to realise that Gerard uses, almost verbatim, the translation of the 'smelly armpit' paragraph from Lyte.

  • Brugmansia suaveolens 'Pink Beauty'
  • Rosa rugosa 'Fru Dagmar Hastrup'
  • 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) 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 with 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).

  • Primula veris L. Primulaceae Cowslip, Herba paralysis Distribution: W. Asia, Europe. Fuchs ((1542) quotes Dioscorides Pliny and Galen, with numerous uses, from bruises, toothache, as a hair dye, for oedema, inflamed eye, and mixed with honey, wine or vinegar for ulcer and wounds, for scorpion bites, and pain in the sides and chest, and more. Lobel (1576) calls them Primula veriflorae, Phlomides, Primula veris, Verbascula. Lyte (1578) calls them Cowslippe, Petie mulleyn, Verbasculum odoratum, Primula veris, Herbae paralysis and Artheticae. Along with cowslips and oxeslips, he says they are 'used dayly among other pot herbes, but in Physicke there is no great account of them. They are good for the head and synewes ...'. Like other herbals of the 16th and 17th century, the woodcuts leave one in no doubt that Primula veris was being written about. However, other translators of Dioscorides (Gunther, 1959 with Goodyear's 1655 translation
  • Vaccinium corymbosum L. Ericaceae Bilberry. Deciduous shrub. Distribution: North America. The berries are eaten and rich in Vitamin C. Native Americans used them as a dressing on acute erysipelas (Milspaugh, 1974). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Geranium sanguineum L. Geraniaceae Dusky cranesbill. Herbaceous perennial. Distribution: Europe and temperate Asia. County flower of Northumberland. This seems to be the 'Sanguin geranium or Blood Roote', Geranium haematodes/haematites, of Lyte (1578). He writes that it is 'not used in Medicyne.' Parkinson (1640) classifies cranesbills somewhat differently, but says that 'all are found to be effectual both in inward and outward wounds, to stay bleedings, vomitings and fluxes, eyther the decoction of the herbe or the powder of the leaves and roots used as the cause demands. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Echinacea purpurea (L.) Moench Asteraceae. Coneflower. Distribution: North America. Austin (2004) records that the roots were chewed, or used as a tincture for coughs by the Choctaw. It was combined with Rhus typhina to treat venereal disease by the Delaware. Very little record of this being used by Native Americans, who used E. angustifolia very widely - Regarded as a panacea and magical herb. This and E. pallida were used to treat snakebite, spider bite, cancer, toothache, burns, sores, wounds, flu and colds. E. purpurea in modern times has been used as an ‘immunostimulant’, but is known to cause a fall in white cell count, and to be purely a placebo. Licensed for use as a Traditional Herbal Medicine, which does not require proof of efficacy, in the UK.
