Solanum laciniatum Aiton Solanaceae. Kangaroo Apple. Evergreen shrub. Distribution: New Zealand and the east coast of Australia. It contains steroidal saponins that can be converted into steroids, including progesterone, oestrogens, cortisone, prednisolone etc. In 1943, Professor Russell Marker discovered a method of obtaining an unsaturated steroidal saponine, diosogenin, from Mexican yam (Dioscorea mexicana), which can easily and cheaply be converted into steroids, such as prednisone and progesterone, reducing the price of steroid production to a fraction (0.5%) of its former cost. For 20 years drug companies showed little interest, and it was only as a result of Professor Marker forming his own company, and the concerted efforts of several gynaecologists, physiologists and birth-control advocates, that the contraceptive pill was ‘born’ in 1960.

Brillantaisia ulugurica Lindau, Acanthaceae. Giant salvia. Tropical herbaceous plant. Distribution: Tropical Africa. Brillantaisia patula is used by the Yoruba in south Nigeria for small-pox medication, the roots being mixed with Bahia nitida and Marantolchloa leucantha, Piper guineense and snails. This is made into a soup and the snail piece eaten to protect against smallpox for a year (Neuwinger, 1994) which doubtless was effective after the global eradication of smallpox in 1979. Brillantaisia nitens is used in the Cameroons to treat cardiovascular disorders. Phytochemical screening of Brillantaisia species have shown antibacterial action, vascular smooth muscle relaxant properties. Kew reports their use as soap

Hepatica nobilis Mill. Ranunculaceae. Liverwort - not to be confused with the lichen of the same name. Distribution: North America. Liverwort (‘liver plant’): discontinued herbal medicine for disorders of the liver. The name and the use to which the Liverworts have been put medicinally is suggested, according to the doctrine of signatures, by the shape of the leaves which are three-lobed, like the liver. It is little used in modern herbalism but was employed in treating disorders of the liver and gall bladder, indigestion etc. It is highly toxic. Hepatica acutiloba was widely used for liver disorders in the 1880s, with up to 200,000 kilos of leaves being harvested per annum to make liver tonics - which eventually caused jaundice. Gerard (1633) calls it Hepaticum trifolium, Noble Liverwort, Golden Trefoile and herbe Trinity and writes: 'It is reported to be good against weakness of the liver which proceedeth from a hot cause, for it cooleth and strengtheneth it not a little. ' He adds ' Baptista Sardus[a Piedmontese physician fl. 1500] commendeth it and writeth that the chiefe vertue is in the root

Cistus incanus ssp creticus Juss. Cistaceae. Rock Rose. Distribution: Crete. Interesting symbiosis with fungus called Tuber melanosporum which increases nutrient absorption for the plant and inhibits growth of other plants in the vicinity. It is a source of the resin ‘labdanum’ (a.k.a. ‘ladanum’) used in perfumes (similar smell to ambergris), as is Cistus ladanifer. It has no medical uses now, and such use was dwindling even in the 18th century. In the 16th century (Henry Lyte’s 1575 translation of Rembert Dodoen’s Cruydeboeck of 1554) its uses were described (directly copied from Dioscorides’ Materia Medica (70AD)) as: ‘Ladanum dronketh with olde wine, stoppeth the laske [periods], and provoketh urine. It is very good against the hardness of the matrix or mother [uterus] layde to in the manner of a pessarie, and it draweth down the secondes or afterbirth, when it is layde upon quicke coles [hot coals], and the fumigation or parfume thereof be received up into the body of women. // The same applied to the head with Myrrhe and oyle of Myrrhe, cureth the scurffe, called Alopecia, and keepeth the heare [hair] from falling of [sic], but whereas it is already fallen away, it will not cause the heare to growe agayne. // ...' and goes on in this vein about its uses for pain in the ears, and removing sores and scars and other things.
