  • 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.

  • 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).

  • Zantedeschia aethiopica (L)Spreng. Calla lily, Arum lily. Half hardy annual. Distribution: South Africa. The genus name commemorates Giovanni Zantedeschi (1773-1846) an Italian physician and botanist. Born in Molina he studied medicine in Verona and Padua. He corresponded with the German botanist, Kurt Sprengel, who named the genus Zantedeschia in his honour in 1826, separating it from Calla, where, as C. aethiopica, it had been previously described by Linnaeus. He had broad interests, including the effect of different parts of the spectrum of light on plant growth, reporting in 1843, that red, orange and yellow light are heliotropically inactive. The botanic museum in Molina is dedicated to his memory. Aethiopica, merely means 'African'. The leaves are used as a warm poultice for headaches in ‘muthi’ medicine. It has become an invasive weed in parts of Australia. It was introduced, as a greenhouse plant, to Europe in the mid-17th century, where the long lasting flowers are popular in flower arranging and for weddings and funerals – a curious combination (Oakeley, 2012).

  • Osmanthus delavayi Franch. Oleaceae Evergreen shrub. Distribution: China. Osmanthus is derived from the Greek for 'fragrant flower', delavayi from its discoverer, the French Missionary with the Missions Étrangères, and plant collector, Pierre Delavay (1834-1895). He sent 200,000 herbarium specimens containing 4000 species including 1,500 new species to Franchet at the Museum of Natural History in Paris. He sent seed of O. delavayi to France (1886), but only one germinated, and all the plants in cultivation until it was recollected 40 years later, arose from this plant (Bretschneider, 1896). The flowers are used to make a tea in China, but the berries (drupes) are not regarded as edible. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
