  • 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.

  • Catharanthus roseus (L.)G.Don Apocynaceae. Madagascar Periwinkle Distribution: Madagascar. It is the source of vincristine and vinblastine, which impair cell multiplication by interfering with microtubule assembly, causing metaphase arrest and are effective medications for leukaemias, lymphomas and some solid tumours. The mortality from childhood leukaemia fell from 100% to 30% once it was introduced - not a drug that could ethically be tested by double-blind trials. These chemicals were initially discovered by investigators in 1958 who were looking for cures for diabetes so tested this plant which was being used in the West Indies to reduce blood sugar levels. There are 70 different alkaloids present in this plant, and some - catharanthine, leurosine sulphate, lochnerine, tetrahydroalstonine, vindoline and vindolinine - lower blood sugar levels. However, the toxicity of this plant is such that this is not a plant to try at home for diabetic management. The vincristine content of the plant is 0.0003%, so two kilograms of leaf are required to produce sufficient vincristine for a single course of treatment for a child (6gm). Fortunately it is a vigorous weed and easy to grow in the tropics. Artificial synthesis has now been achieved. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • Erythroxylum coca Lam. Erythroxylaceae Coca. Distribution: Peru . Cocaine is extracted from the leaf. It is no longer in the UK Pharmacopoeia (used to be used as a euphoriant in ‘Brompton Mixture’ for terminally ill patients). Cocaine, widely used as a local anaesthetic until 1903, inhibits re-uptake of dopamine and serotonin at brain synapses so these mood elevating chemicals build up and cause a ‘high’. Its use was often fatal. Coca leaf chewing was described by Nicolas Monardes (1569
