  • Veratrum nigrum L. Melanthiaceae Distribution: Europe. Cows do not eat Veratrum species in the meadows, and human poisoning with it caused vomiting and fainting. In the 1850s it was found to reduce the heart's action and slow the pulse (Bentley, 1861, called it an 'arterial sedative'), and in 1859 it was used orally in a woman who was having convulsions due to eclampsia. Dr Paul DeLacy Baker in Alabama treated her with drops of a tincture of V. viride. She recovered. It was used thereafter, as the first choice of treatment, and, when blood pressure monitoring became possible, it was discovered that it worked by reducing the high blood pressure that occurs in eclampsia. By 1947 death rates were reduced from 30% to 5% by its use at the Boston Lying-in Hospital. It works by dilating the arteries in muscles and in the gastrointestinal circulation. A further use of Veratrum species came to light when it was noted that V. californicum - and other species - if eaten by sheep resulted in foetal malformations, in particular only having one eye. The chemical in the plant that was responsible, cyclopamine, was found to act on certain genetic pathways responsible for stem cell division in the regulation of the development of bilateral symmetry in the embryo/foetus. Synthetic analogues have been developed which act on what have come to be called the 'hedgehog signalling pathways' in stem cell division, and these 'Hedgehog inhibitors' are being introduced into medicine for the treatment of various cancers like chondrosarcoma, myelofibrosis, and advanced basal cell carcinoma. The drugs are saridegib, erismodegib and vismodegib. All the early herbals report on its ability to cause vomiting. As a herbal medicine it is Prescription Only, via a registered dentist or physician (UK Medicines and Healthcare Products Regulatory Agency (MHRA)).

  • Papaver somniferum L. Papaveraceae Opium Poppy Distribution: Asia minor, but has been dated to 5000BC in Spanish caves. Now grows almost everywhere. The oldest medicine in continuous use, described in the Ebers' papyrus (1550 BC), called Meconium, Laudanum, Paregoric and syrup of poppies. Culpeper (1650) on Meconium '...the juyce of English Poppies boyled till it be thick' and 'I am of the opinion that Opium is nothing else but the juyce of poppies growing in hotter countries, for such Opium as Authors talk of comes from Utopia.[he means an imaginary land, I suspect]’]. He cautions 'Syrups of Poppies provoke sleep, but in that I desire they may be used with a great deal of caution and wariness...' and warns in particular about giving syrup of poppies to children to get them to sleep. The alkaloids in the sap include: Morphine 12% - affects ?-opioid receptors in the brain and causes happiness, sleepiness, pain relief, suppresses cough and causes constipation. Codeine 3% – mild opiate actions – converted to morphine in the body. Papaverine, relaxes smooth muscle spasm in arteries of heart and brain, and also for intestinal spasm, migraine and erectile dysfunction. Not analgesic. Thebaine mildly analgesic, stimulatory, is made into oxycodone and oxymorphone which are analgesics, and naloxone for treatment of opiate overdose – ?-opioid receptor competitive antagonist – it displaces morphine from ?-opioid receptors, and constipation caused by opiates. Protopine – analgesic, antihistamine so relieves pain of inflammation. Noscapine – anti-tussive (anti-cough). In 2006 the world production of opium was 6,610 metric tons, in 1906 it was over 30,000 tons when 25% of Chinese males were regular users. The Opium wars of the end of the 19th century were caused by Britain selling huge quantities of Opium to China to restore the balance of payments deficit. Laudanum: 10mg of morphine (as opium) per ml. Paregoric: camphorated opium tincture. 0.4mg morphine per ml. Gee’s Linctus: up to 60 mg in a bottle. J Collis Browne’s chlorodyne: cannabis, morphine, alcohol etc. Kaolin and Morph. - up to 60 mg in a bottle. Dover’s Powders – contained Ipecacuana and morphine. Heroin is made from morphine, but converted back into morphine in the body (Oakeley, 2012). One gram of poppy seeds contains 0.250mgm of morphine, and while one poppy seed bagel will make a urine test positive for morphine for a week, one would need 30-40 bagels to have any discernible effect.

  • Senna corymbosa (Lam.)H.S.Irwin&Barneby Caesalpinaceae. Argentine Senna. Distribution: Argentine (other species from Europe). This beautiful shrub that flowers from midsummer until the frosts of winter, is the source of one of the best known of all herbal medicines – Senokot (and senna pods and senna tea), introduced to European medicine (as Senna alexandrina from Egypt) by the Arabians. Every part of the plant contains anthraquinones which, if taken internally, act as a powerful laxative to treat constipation by stimulating the nerve cells of the large bowel. Gerard (1633) notes ‘it is a singular purging medicine’ with over a page on its uses. When used regularly the nerves to the large bowel may be destroyed, leaving a permanently dilated large bowel that never functions properly again. This is a plant which causes the condition it treats to become permanent. Additionally, with prolonged use, the lining of the bowel turns black, serum potassium levels may fall, resulting in cardiac irregularities and sometimes death. Coma, neuropathy and hepatitis have also been reported. It is advertised on television (the actor involved is seen to be depressed and bloated until she takes Senokot, after which she is happy - Hippocrates would have attributed this antidepressant effect to the plant's ability to purge her of the black melancholic humour present in her bowel motions). It is available without prescription or health warning against long-term use. What do you think? Lyte (1578) recommends it strongly for depression, but one might claim to be cured rather than take it again. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Euphorbia milii Des Moul. Euphorbiaceae. Crown of Thorns - so called because of its very spiny stems. Distribution: Madagascar. The latex contains a copper-containing amine oxidase, a lectin, lipase, peroxidase, and a diamine oxidase. In vitro the latex is synergistic with ketoconazole against Candida albicans (thrush). All Euphorbia have a toxic white latex, and in Europe this has been used as a folk remedy to treat warts. It can cause skin allergies and the smoke from burning them is toxic. the genus named for Euphorbus (fl. circa 10 BC – 20 AD), the Greek physician to the Berber King Juba II (c. 50 BC – 23 AD) of Numidia, Euphorbia milii is one of the tropical spurges, with fierce, cactus-like spines, grown as a house plant. The sap of spurges is used in folk medicine for treating warts (not very effective), and, historically, as a purgative - the word spurge being derived from the French word for purgation. The sap (probably dried) was administered inside a fig because it is so corrosive that it would otherwise burn the mouth and oesophagus – a technique used today, rather more subtly, with ‘enteric coated’ medications. The sap contains a potential anti-leukaemic chemical, lasiodoplin, and is also used in drainage ditches to kill the snails which carry the parasitic trematode which causes fasciolaris. It does not kill the fish. 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)).
