  • Athyrium niponicum (Mett.) Hance var. pictum (Maxwell) Fraser-Jenk. Woodsiaceae. Japanese Painted fern. Hardy fern. Distribution: Japan. Young fronds are boiled and eaten in Japan. However after the discovery of thaiminases in certain ferns Pteridum aquilum (bracken), Marsilea drummondii and Cheilanthes sieberi cautions are given regarding the risk of thiaminase in all ferns. It can be mostly removed by boiling, but otherwise causes vitamin B1 (thiamine) deficiency and beriberi in a matter of weeks. Eating Bracken fern also causes cancer, as do the spores, but I could find no report of other ferns being toxic. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Helleborus x hybridus Hort. Ex Vilmorin Ranunculaceae. A range of hybrids from Helleborus orientalis the Oriental hellebore. Distribution: Europe through to the Caucasus. All very poisonous.

  • Oenothera macrocarpa Nutt. Onagraceae. Ozark Sundrops, Bigfruit Evening Primrose. Formerly O. missouriensis. Distribution: South central USA.

Leaves as salad, roots boiled like potato also infusion to treat obesity and relieve piles (Cherokee)
  • 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.

  • 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.

  • 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
  • Polygonum bistorta L. Polygonaceae Bistort, snakeweed, Easter Ledges. Distribution: Europe, N & W Asia. Culpeper: “... taken inwardly resist pestilence and poison, helps ruptures, and bruises, stays fluxes, vomiting and immoderate flowing of the terms in women, helps inflammations and soreness of the mouth, and fastens loose teeth, being bruised and boiled in white wine and the mouth washed with it.” In modern herbal medicine it is still used for a similar wide variety of internal conditions, but it can also be cooked and eaten as a vegetable. The use to relieve toothache, applied as a paste to the affected tooth, seems to have been widespread. 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.
  • 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.
