  • Aubergine or egg plant (Solanum melongena): fruits of different varieties. Chromolithograph, c. 1870, after H. Briscoe.

  • A plant (Solanum sp.): flowering and fruiting stem with separate sectioned fruit and seed. Coloured etching by M. Bouchard, 1774.
  • Four poisonous plants: monk's hood (Aconitum napellus), deadly nightshade (Atropa belladonna), woody nightshade (Solanum dulcamara) and thorn-apple (Datura stramonium) Coloured engraving by J. Johnstone, 1855.
  • 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.
  • Solanum laciniatum Aiton Solanaceae. Kangaroo Apple. Evergreen shrub. Distribution: New Zealand and the east coast of Australia. It contains steroidal saponins that can be converted into steroids, including progesterone, oestrogens, cortisone, prednisolone etc. In 1943, Professor Russell Marker discovered a method of obtaining an unsaturated steroidal saponine, diosogenin, from Mexican yam (Dioscorea mexicana), which can easily and cheaply be converted into steroids, such as prednisone and progesterone, reducing the price of steroid production to a fraction (0.5%) of its former cost. For 20 years drug companies showed little interest, and it was only as a result of Professor Marker forming his own company, and the concerted efforts of several gynaecologists, physiologists and birth-control advocates, that the contraceptive pill was ‘born’ in 1960. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
  • Atropa belladonna L. Solanaceae. Deadly nightshade. Dwale. Morella, Solatrum, Hound's berries, Uva lupina, Cucubalus, Solanum lethale. Atropa derives from Atropos the oldest of the three Fates of Greek mythology who cut the thread of Life (her sisters Clotho and Lachesis spun and measured the thread, respectively). belladonna, literally, means 'beautiful lady' and was the Italian name for it. Folklore has it that Italian ladies put drops from the plant or the fruits in their eyes to make themselves doe-eyed, myopic and beautiful. However, this is not supported by the 16th and 17th century literature, where no mention is ever made of dilated pupils (or any of the effects of parasympathetic blockade). Tournefort (1719) says 'The Italians named this plant Belladonna, which in their language signifies a beautiful woman, because the ladies use it much in the composition of their Fucus [rouge or deceit or cosmetic] or face paint.' Parkinson says that the Italian ladies use the distilled juice as a fucus '... peradventure [perhaps] to take away their high colour and make them looke paler.' I think it more likely that they absorbed atropine through their skin and were slightly 'stoned' and disinhibited, which made them beautiful ladies in the eyes of Italian males. Distribution: Europe, North Africa, western Asia. Culpeper (1650) writes: 'Solanum. Nightshade: very cold and dry, binding … dangerous given inwardly … outwardly it helps the shingles, St Antonie's Fire [erysipelas] and other hot inflammation.' Most of the 16th, 17th and 18th century herbals recommend it topically for breast cancers. Poisonous plants were regarded as 'cold' plants as an excess of them caused death and the body became cold. They were regarded as opposing the hot humour which kept us warm and alive. Poultices of Belladonna leaves are still recommended for muscle strain in cyclists, by herbalists. Gerard (1633) writes that it: 'causeth sleep, troubleth the mind, bringeth madnesse if a few of the berries be inwardly taken, but if more be taken they also kill...'. He was also aware that the alkaloids could be absorbed through the skin for he notes that a poultice of the leaves applied to the forehead, induces sleep, and relieves headache. The whole plant contains the anticholinergic alkaloid atropine, which blocks the peripheral actions of acetylcholine in the parasympathetic nervous system. Atropine is a racemic mixture of d- and l- hyoscyamine. Atropine, dropped into the eyes, blocks the acetylcholine receptors of the pupil so it no longer constricts on exposure to bright light - so enabling an ophthalmologist to examine the retina with an ophthalmoscope. Atropine speeds up the heart rate, reduces salivation and sweating, reduces gut motility, inhibits the vertigo of sea sickness, and is used to block the acetylcholine receptors to prevent the effects of organophosphorous and other nerve gas poisons. It is still has important uses in medicine. Atropine poisoning takes three or for days to wear off, and the hallucinations experienced by its use are described as unpleasant. We have to be content with 'madness', 'frenzie' and 'idle and vain imaginations' in the early herbals to describe the hallucinations of atropine and related alkaloids as the word 'hallucination' in the sense of a perception for which there is no external stimulus, was not used in English until 1646 (Sir T. Browne, 1646). It is a restricted herbal medicine which can only be sold in premises which are registered pharmacies and by or under the supervision of a pharmacist (UK Medicines and Healthcare Products Regulatory Agency (MHRA)).

  • Paris quadrifolia L. Trilliaceae Herb Paris Distribution: Europe and temperate Asia. This dramatic plant was known as Herb Paris or one-berry. Because of the shape of the four leaves, resembling a Burgundian cross or a true love-knot, it was also known as Herb True Love. Prosaically, the name ‘Paris’ stems from the Latin ‘pars’ meaning ‘parts’ referring to the four equal leaves, and not to the French capital or the lover of Helen of Troy. Sixteenth century herbalists such as Fuchs, who calls it Aconitum pardalianches which means leopard’s bane, and Lobel who calls it Solanum tetraphyllum, attributed the poisonous properties of Aconitum to it. The latter, called monkshood and wolfsbane, are well known as poisonous garden plants. Gerard (1633), however, reports that Lobel fed it to animals and it did them no harm, and caused the recovery of a dog poisoned deliberately with arsenic and mercury, while another dog, which did not receive Herb Paris, died. It was recommended thereafter as an antidote to poisons. Coles (1657) wrote 'Herb Paris is exceedingly cold, wherupon it is proved to represse the rage and force of any Poyson, Humour , or Inflammation.' Because of its 'cold' property it was good for swellings of 'the Privy parts' (where presumably hot passions were thought to lie), to heal ulcers, cure poisoning, plague, procure sleep (the berries) and cure colic. Through the concept of the Doctrine of Signatures, the black berry represented an eye, so oil distilled from it was known as Anima oculorum, the soul of the eye, and 'effectual for all the disease of the eye'. Linnaeus (1782) listed it as treating 'Convulsions, Mania, Bubones, Pleurisy, Opththalmia', but modern authors report the berry to be toxic. That one poison acted as an antidote to another was a common, if incorrect, belief in the days of herbal medicine. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
