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 with 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).

Eranthis hyemalis Salisb. Ranunculaceae Winter Aconite Distribution: Europe. The reason it was called Winter aconite and linked to Aconitum napellus as being just as poisonous is because plants were classified according to leaf shape in the 16th century. L'Obel's Stirpium adversaria nova (1571) and Plantarum seu stirpium historia (1576) (with a full page illustration on page 384 showing Eranthis and Aconitum together) along with the knowledge that related plants have similar medical properties caused the belief that Eranthis are as poisonous as Aconitum. They are both in Ranunculaceae and while Eranthis (like all Ranunculaceae)is toxic if eaten, it does not contain the same chemicals as Aconitum. Caesalpino (Ekphrasis, 1616) pointed out the error in classifying according to leaf shape and recommended flower shape. It contains pharmacologically interesting chemicals such as khellin, also present in Ammi visnaga. This is a vasodilator but quite toxic, but can be converted into khellin analogues such as sodium cromoglicate – used as a prophylaxis against asthma attacks – and amiodarone which has anti-arrhythmia actions so is used for atrial fibrillation and other arrhythmias. It is endangered and protected in the wild (Croatia) because of over-collecting for horticulture. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Cytisus scoparius (L.) Link Fabaceae. Common broom, Genista. Distribution: Western and central Europe. Culpeper (1650) writes: 'Genista. Broom: … clense and open the stomach, break the stone in the reins [kidneys] and bladder, help the green sickness [anaemia]. Let such as are troubled with heart qualms or faintings, forbear it, for it weakens the heart and spirit vital' and in respect of the flowers he writes: 'Broome-flowers, purge water, and are good in dropsies [now regarded as heart failure with fluid retention].'
