Petasites hybridus (L.)G.Gaertn., B.Mey. & Scherb. Asteraceae. Butterbur, Bog rhubarb. Distribution: Europe, NW Asia. Culpeper (1650) writes: “The roots are ... exceeding good in violent and pestilential fevers, they provoke the terms, expel poison, and kill worms.” Modern herbalists recommend it for a wide range of therapies, but it contains pyrrolizidine alkaloids, which are hepatotoxic and cause liver cancers. Nevertheless, in a trial aimed at reducing frequency of migraine attacks, a standardised commercial preparation was well tolerated, and was effective at higher doses, but placebo in this trial reduced migraines by over 50% in 49% of the patients (Neurology 2004

Eucryphia glutinosa (Poepp. & Endlich.) Baill. Eucryphiaceae. Santo sour cherry. Woodland tree. Distribution: Ancient genus from Gondwanaland. Native of Chile, other species being found in eastern coastal Australia. It is now rare in its habitat, since it was much used as a timber tree. Australian aboriginals have used leatherwood (Eucryphia lucida) as an antiseptic and styptic. A recent investigation by the Australian Government Rural Industries and Development Corporation (B R D’Arcy, 2005) finds that leatherwood honey is rich in phenolic acids that possess some antibacterial and anti-oxidant activity. These natural products have been proposed as preservers of freshness in foodstuffs - a possible alternative to the synthetics currently used.

Athyrium niponicum (Mett.) Hance var. pictum (Maxwell) Fraser-Jenk. Woodsiaceae. Japanese Painted fern. Hardy fern. Distribution: Japan. Young fronds are boiled and eaten in Japan. However after the discovery of thaiminases in certain ferns Pteridum aquilum (bracken), Marsilea drummondii and Cheilanthes sieberi cautions are given regarding the risk of thiaminase in all ferns. It can be mostly removed by boiling, but otherwise causes vitamin B1 (thiamine) deficiency and beriberi in a matter of weeks. Eating Bracken fern also causes cancer, as do the spores, but I could find no report of other ferns being toxic. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
