Lathyrus vernus (L.)Bernh. Papilionaceae previously Orobus vernus L. (Linnaeus, 1753) Spring vetchling. Distribution: Europe to Siberia. The seeds of several Lathyrus species are toxic, and when eaten cause a condition called lathyrism. The chemical diaminoproprionic acid in the seeds causes paralysis, spinal cord damage, aortic aneurysm, due to poisoning of mitochondria causing cell death. Occurs where food crops are contaminated by Lathyrus plants or where it is eaten as a 'famine food' when no other food is available. It is the Orobus sylvaticus purpureus vernus of Bauhin (1671) and Orobus sylvaticus angustifolius of Parkinson (1640) - who records that country folk had no uses for it. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Iris graminea L. Iridaceae Grass-leaved flag. Flower de Luce. Distribution: Central and Southern Europe. This is probably the Iris bulbosa minor sive angustifolia [the lesser bulbed or narrow-leaved Iris], Lesser bulbed Flower de luce of Parkinson (1640). He advised that the properties of all Flag Irises were more or less the same, but says there is no agreement about the properties of the bulbous kinds (such as this plant). Of the Flag Irises, Culpeper (1650) writes that the roots 'resist poison, help shortness of the breath, prove the terms [menstruation]

Stachys byzantina K.Koch also known as Stachys lanata. Lamiaceae. Lamb's Ears. Distribution: Europe. Its woolly leaves were regarded as a vulnery, to stop bleeding, which it would have done in a manner similar to cotton-wool, allowing platelets to clot on its hairs.

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.

Dactylorhiza foliosa (Rchb.f.)Soo Orchidaceae Distribution: Madeira. Roots look like a hand and Coles (1657) calls them Palma Christi sive [or] Satyrion (to distinguish it from Ricinus communis which he calls Palma Christi sive Ricinus. This plant would be the closest to his Male Satyrion Royal, with purple flowers (but this is likely to be one of the English Marsh orchids,, and Dactylorhiza fuchsii is his Female Satyrion. In common with Orchis he writes 'The full and plump roots of the Satyrium or Orchis, whereof the Electuary Diasatyrium is made, are of mighty efficacy to provoke to venery, which they that have bulbous roots [meaning the testicle shaped roots of Orchis] do by Signature.'. Terrestrial orchids continue to be harvested by the millions annually in the Middle East for the production of Salep, including Salep ice cream, because of their mythological aphrodisiacal property. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

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.
