Purple bacteria or purple photosynthetic bacteria are pigmented by bacteriochlorophyll and carotenoids, giving them a colourful range of purples, pinks and oranges. They photosynthesize without producing oxygen as a by-product. This type of bacteria are proteobacteria which are phototrophic (produce their own food via photosynthesis)

Solanum atropurpureum Schrank Solanaceae. Purple Devil. Purple-spined Nightshade. Herbaceous perennial. Distribution: Brazil. This ferociously spined plant contains tropane alkaloids, atropine, hyoscyamine and scopolamine. All are anticholinergic and block the acetylcholine mediated actions of the parasympathetic nervous system. While the alkaloids are used in medicine and as an antidote to anticholinergic nerve gas poisons, the plant itself is not used in medicine. Its sharp spines can be irritant. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Prostanthera ovalifolia R.Br. Lamiaceae Alpine anise bush, Oval leaf Mintbush, Purple mintbush. Woody shrub. Distribution: Australia. Minty flavoured leaves used in jams and jellies. Various essential oils are produced from commercially grown P. ovalifolia (cis-dihydroagarofuran, kessane, 1,8-cineole which is also known as eucalyptol, p-cymene,) and P. cuneata also contains eucalyptol. Concentrations of essential oils in the plants vary according to the clonal variety, growing conditions and time of year. Aboriginal peoples used Prostanthera leaves in medicinal ointments and washes, but one species, P. striatiflora, was used to poison waterholes to kill visiting emu (Hegarty, 2001).

Dactylorhiza aff fuchsii Druce ex Soo Orchidaceae Common Spotted orchid. Distribution: Ireland to Mongolia. Roots look like a hand. Coles (1657) calls them Palma Christi sive [or] Satyrion (to distinguish it from Ricinus communis which he calls Palma Christi sive Ricinus. This plant is probably his Female Satyrion and another Dactylorhiza, probably one of the English Marsh orchids, is his Male Satyrion Royal, with purple flowers. 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.

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.'.

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.
