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

Nigella sativa L. Ranunculaceae Love-in-the-mist, Black Cumin, Nutmeg flower, Roman Coriander. Distribution: SW Asia. Culpeper (1650) writes: ‘Nigella seeds, boyled in oil, and the forehead anointed with it, ease pains in the head, take away leprosie, itch, scurf, and helps scald-heads, inwardly taken they expel worms, they provoke urine and the terms, help difficulty of breathing: the smoke of them (being burned) drives away serpents and venomous beasts.’ The seeds are used as a spice, but as might be expected as a member of the family Ranunculaceae, the buttercups, the plant contains a highly poisonous glycoside, in this case called melanthin. The amount of toxicity present in spices is clearly insufficient to cause problems when used as such. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Cellular architecture of normal human skin imaged by whole mount tissue microscopy. Human skin has a rich network of white blood cells (specifically dendritic cells, T cells and macrophages) which form sheaths around blood vessels. In this image, T cells (stained for CD3; red) dendritic cells (stained for MHC class II; green) and macrophages (stained for LYVE-1; blue with some cells showing a tinge of green) can be seen. Cell nuclei have been stained with DAPI (grey). This normal cellular architecture is grossly disrupted in diseased skin (see related images). X20 magnification. Scale bar (white) represents 100 micrometres.
