  • Erythrina crista-galli L. Fabaceae. Cockspur coral tree. Distribution: South America. The national tree of Argentina, its flowers are pollinated by perching birds unlike many other species which are pollinated by humming birds. An extract from the bark is used as a powerful soporific, also as a gargle for sore throats and in the treatment of cuts, rheumatism and hepatitis, in Brazil (Mors, 1998). The seed contains the alkaloid beta-erythroidine. Analgesics, antimicrobial and anti inflammatory substances are being sought from the leaves. Curare-like action in rats has been reported from the seeds. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

  • 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.

  • Glaucium flavum Crantz Papaveraceae Yellow horned poppy. Distribution: North Africa, Western Asia to Europe. Contains glaucine which is toxic but in small doses may be bronchodilator. As Papaver corniculatum luteum it was known to Parkinson (1640) who reports it as bitter, so advises taking it in honey, as a purgative and analgesic

  • Nepal; Sherpa porters in the Khumbu, 1986. Well-dressed Sherpa porters prepare for a trekking expedition organised for a party of western vacationists. They will guide, bring up the rear, cook and strike camp. Such expeditions pay cash wages far in excess of anything Sherpas could hope to earn elsewhere and such income is invested in loans, cattle, land, tradeable articles and jewellery. Until the influx of mountaineering expeditions following Hillary's Everest climb (1953), western medicine was unknown in the Khumbu. Distribution of mainly analgesic and antibiotic drugs has led to misuse.
  • Chamaemelum nobile (L.) All. Asteraceae. English, Roman or garden chamomile Distribution: Europe, Mediterranean. Culpeper (1650): “... assuage swellings, inflammations of the bowels, dissolve wind, are profitable given in clysters or drink, to such as are troubled with colic or [renal] stone.” The leaves are pleasantly fragrant, hence its use as a lawn plant, but also in aromatherapy. A ‘tea’ made from the flowers is apparently used to lighten hair colour. Chamomile contains sesquiterpene lactones, and these are known to possess allergenic properties. Hypersensitivity reactions have been reported in this and other members of the Compositae (Asteraceae) and cross sensitivity reactions may occur (Medicines Control Agency, 2002). Analgesic, and used for cramps and spasms (Quincy, 1718). Chamomile tea is used to help sleep, but may cause uterine contractions so avoid in pregnancy (US National Institutes of Health advice).
