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, blood vessels (string-like structures stained for CD31; green), lymphatic vessels (ribbon-like structures stained for LYVE-1; blue) and T cells (stained for CD3; red) can be seen. T cells are only found around dermal blood vessels. Macrophages (stained for LYVE-1; blue) are also present. This normal cellular architecture is grossly disrupted in diseased skin (see related images). X10 magnification. Scale bar (white) represents 200 micrometres.

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

Danae racemosa (L.) Moench Asparagaceae. Alexandrian or Poet's laurel. Distribution: Turkey to Iran. A monotypic genus with supreme adaptation to dry conditions, bearing its flowers and fruits on phylloclades, leaf like expanded stems. The phylloclades are too thick for sunlight to pass through so have chlorophyll containing cells on both sides (the cells in the middle do not) and stomata on both sides to facilitate CO2 diffusion into the plant. Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Root extracts have been shown to have cytotoxic and anti-inflammatory action in experimental situations. Euphorbia species all have toxic sap, and had many names in early literature, eg esula, about which Culpeper (1650) says that '(taken inwardly) are too violent for vulgar use
