  • Acacia melanoxylon R.Br. Mimosaceae. Australian Blackwood. Tree. Distribution: Eastern Australia. Tree. Invasive weed in South Africa, Portugal, California. Local uses: analgesic. Causes allergic contact dermatitis due to 2,6,dimethoxybenzoquinone. Pinnate leaves of young plant drop off and phylloclades are formed instead. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Hydrangea quercifolia W.Bartram Hydrangeaceae. Oak-leaved hydrangea. Distribution: South-eastern United States. Beta-dichroine a quinazolinone also called febrifugine from the leaves of hydrangeas is 64-100 times more potent than quinine as an antimalarial in animals, but extremely toxic. A synthesised tolyl derivative, methaqualone (2-methyl-3-o-tolyl-4(3H)-quinazolinone), was found to be a mild hypnotic, and marketed in the sleeping tablet, Mandrax. Widely abused and quickly banned by most countries. Illegal manufacture continues and in South Africa methaqualone is the commonest drug of abuse, mixed with cannabis and smoked. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Gardenia jasminoides J.Ellis Rubiaceae. Cape jasmine - as erroneously believed to have come from South Africa. Distribution: China. Named for Dr Alexander Garden FRS (1730-1791) Scottish-born physician and naturalist who lived in Charles Town, South Carolina, and corresponded with Linnaeus and many of the botanists of his era. The fruits are used in China both as a source of a yellow dye, and for various unsubstantiated medicinal uses. Other species of Gardenia are found in tropical Africa and the roots and leaves have all manner of putative uses. Gardenia tenuifolia is used as an aphrodisiac, for rickets, diarrhoea, leprosy, gall bladder problems, toothache, liver complaints, diabetes, hypertension, malaria and abdominal complaints. It causes violent vomiting and diarrhoea. It, and other species, are used to poison arrows and to poison fish. Some native, muthi medicine, healers regard Gardenia as a ‘last chance’ medicine, given to patients when all else fails – the patient either dies or recovers (Neuwinger, 1996). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Eucomis comosa (Houtt.)H.R.Wehrh. Hyacinthaceae Pineapple flower. From the Greek eu comis meaning 'good hair' referring to the tuft of leaves on top of the flowers. Comosa being Latin for 'with a tuft' referring to the same thing. Used in South African 'muthi' medicine. Enemas of Eucomis autumnalis are used in Africa to treat low backache, to aid postoperative recovery and to speed the healing of fractures. Decoctions are taken for the treatment of everything from hangovers to syphilis. The active ingredients include homisoflavones, which have anti-inflammatory and antispasmodic activity (van Wyk et al, 2000) Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Albizia julibrissin Durazz. Fabaceae. Persian silk tree. Called 'shabkhosb' in Persian, meaning 'sleeping tree' as the pinnate leaves close up at night. Tropical tree. Named for Filippo degli Albizzi, an Italian naturalist, who brought seeds from Constantinople to Florence in 1749, and introduced it to European horticulture. The specific epithet comes from the Persian 'gul-i abrisham' which means 'silk flower'. Distribution: South Africa to Ethiopia, Senegal, Madagascar, Asia. Bark is poisonous and emetic and antihelminthic. Various preparations are widely used for numerous conditions and the oxitocic albitocin is abortifacient. However, studies on the seeds and bark of other Albizia species in Africa, demonstrate it is highly toxic, half a kilogram of seeds given to a quarter ton bull, killed it in two hours (Neuwinger, 1996). A useful tree for controlling soil erosion, producing shade in coffee plantations, and as a decorative shade tree in gardens. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Plumbago auriculata Blume Plumbaginaceae Plumbago, Leadwort. Distribution: South Africa. It is used traditionally to treat warts, broken bones and wounds. It is taken as a snuff for headaches and as an emetic to dispel bad dreams. A stick of the plant is placed in the thatch of huts to ward off lightning.” Iwou (1993) reports other Plumbago species are used to cause skin blistering, treat leprosy, induce blistering, and to treat piles, parasites and to induce abortions. The genus name derives from the Latin for lead, but authors differ as to whether it was used as a treatment of lead poisoning, or that when it was used for eye conditions the skin turned the colour of lead. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Zantedeschia aethiopica (L)Spreng. Calla lily, Arum lily. Half hardy annual. Distribution: South Africa. The genus name commemorates Giovanni Zantedeschi (1773-1846) an Italian physician and botanist. Born in Molina he studied medicine in Verona and Padua. He corresponded with the German botanist, Kurt Sprengel, who named the genus Zantedeschia in his honour in 1826, separating it from Calla, where, as C. aethiopica, it had been previously described by Linnaeus. He had broad interests, including the effect of different parts of the spectrum of light on plant growth, reporting in 1843, that red, orange and yellow light are heliotropically inactive. The botanic museum in Molina is dedicated to his memory. Aethiopica, merely means 'African'. The leaves are used as a warm poultice for headaches in ‘muthi’ medicine. It has become an invasive weed in parts of Australia. It was introduced, as a greenhouse plant, to Europe in the mid-17th century, where the long lasting flowers are popular in flower arranging and for weddings and funerals – a curious combination (Oakeley, 2012). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • 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). Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • 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.

  • Cynoglossum officinale L. Boraginaceae. Houndstongue. Distribution: Europe. Culpeper (1650) writes: “... being roasted and laid to the fundament, helps the haemorrhoids. It is also good against burnings and scaldings.” It contains hepatocarcinogenic pyrrolizidine alkaloids and while people are known to eat the young leaves as a vegetable, this is inadvisable. The whole plant is hairy and may cause contact dermatitis. The use of herbal remedies, which contain these alkaloids, by the Bantu of southern Africa correlates with their high incidence of tumours of the liver and pancreas. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Scabiosa columbaria L. Dipsacaceae. Small scabious. Distribution: Europe. Culpeper (1650) writes: ‘The roots either boiled or beaten into powder and so taken, helps such as are extremely troubled with scabs and itch, are medicinal in the French-pocks [syphilis], hard swellings, inward wounds ...’ The genus name comes from the Latin word scabies, meaning ‘itch’. According to the Doctrine of Signatures, the rough leaves indicated that it would cure eczematous skin. However, the leaves are not really very rough... Not used in herbal medicine at the present time except in Southern Africa where it is used for colic and heartburn, and the roots made into an ointment for curing wounds (van Wyk, 2000). 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, Dodoens Histoire des Plantes (1575) does not mention these latter uses, but Dodoen's own Latin translation, the Pemptades (1583), and Gerard's Herbal (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.
