Punica granatum L. Lythraceae Pomegranate, granatum malum, balustines. Distribution: E. Mediterranean to Himalayas. The Pomegranate is in the centre of the Arms of the Royal College of Physicians, perhaps for its use in cooling, and therefore for fevers. However it was the sour pomegranate that would have been used as Dioscorides says the sweet ones are unfit for use in agues. Culpeper (1650) makes no mention of the fruit, but says of the flowers ‘... they stop fluxes and the Terms in women.’ In the Complete Herbal and English Physician (1826) says the fruit ‘... has the same general qualities as other acid fruits.’ Of the flowers he says (among other properties) that ‘A strong infusion of these cures ulcers in the mouth and throat, and fastens loose teeth.’ Gerard (1633) says that the cravings of pregnant women can be abolished with the juice, and perhaps it was scurvy which was being treated effectively when he reports that the juice was very effective against splitting of blood and for loose teeth. The dwarf form of this species, Punica granatum var. nana has fruits no more than 3cm across. Pomegranate bark can only be sold by registered pharmacies in the UK and used to be used as a vermifuge, with the secondary use that the tincture made from it doubled as a permanent ink. In South Africa the fruit rind is used for diarrhoea and stomach ache, and the bark as a vermifuge, but undesirable side effects make this dangerous. It is reported to be effective against fevers, as a diuretic, to lower blood sugar and to be both antibacterial and antiviral (van Wyk, 2000).

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). Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Helianthus annuus Greene Asteraceae. Sunflower, Marigold of Peru, Floure of the Sun. Distribution: Peru and Mexico. It was much recommended by Gerard (1633) who advises that the buds, covered in flour, boiled, and eaten with 'butter, vinegar and pepper, far surpass artichokes in procuring bodily lust’. Sadly, today only the seeds of sunflower are consumed, as the source of sunflower seed oil used in cooking. It contains mono and polyunsaturated fats, linoleic acid and oleic acid, and is low in saturated fats. As such it was thought to lower cholesterol and so the risk of heart disease, but it may increase the risk of breast and prostatic cancer. However a recent report BMJ2013

Agrimonia eupatoria L. Agrimony, Eupatorium, Maudlein. Perennial herb. The species name comes from king Mithridates Eupator VI of Pontus (132-63 BC) who took regular doses of poison to develop an immunity to them. A 'Mithridate' was a medicine against poisons. Distribution: N. and S. Africa, N. Asia, Europe. '…provokes urine and the terms [periods], dries the brain, opens stoppings, helps the green sickness [iron deficiency anaemia], and profits such as have a cold weak liver outwardly applied it takes away the hardness of the matrix [=uterus] and fills hollow ulcers with flesh' (Culpeper, 1650). Dioscorides (Beck, 2005) recommends mashed leaves in hog's grease for healing scarring ulcers, and the seed in wine for dysentery and serpent bites. Goodyear's 1655 translation of Dioscorides (Gunther 2000) has this as cannabis, which Parkinson (1640) says is in error and summarises the manifold uses from classical authors, from removing splinters to stopping menorrhagia. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Primula veris L. Primulaceae Cowslip, Herba paralysis Distribution: W. Asia, Europe. Fuchs ((1542) quotes Dioscorides Pliny and Galen, with numerous uses, from bruises, toothache, as a hair dye, for oedema, inflamed eye, and mixed with honey, wine or vinegar for ulcer and wounds, for scorpion bites, and pain in the sides and chest, and more. Lobel (1576) calls them Primula veriflorae, Phlomides, Primula veris, Verbascula. Lyte (1578) calls them Cowslippe, Petie mulleyn, Verbasculum odoratum, Primula veris, Herbae paralysis and Artheticae. Along with cowslips and oxeslips, he says they are 'used dayly among other pot herbes, but in Physicke there is no great account of them. They are good for the head and synewes ...'. Like other herbals of the 16th and 17th century, the woodcuts leave one in no doubt that Primula veris was being written about. However, other translators of Dioscorides (Gunther, 1959 with Goodyear's 1655 translation
