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. This image was taken less than 20 micrometres beneath the junction that joins the dermal and epidermal layers of the skin (dermo-epidermal junction). At this level, dendritic cells (stained for CD11c; green) form clusters around and between blood capillary loops (stained for CD31; red). The blind-ended tips of initial lymphatic vessels are just visible (stained for LYVE-1; blue) at this level. This normal cellular architecture is grossly disrupted in diseased skin (see related images). Scale bar (white) represents 200 micrometres.

Pulsatilla vulgaris Mill. Ranunculaceae. Pasque flower. Distribution: Europe. Lindley (1838) and Woodville (1790) knew this as Anemone pulsatilla, the common name being Pasque (Easter) Flower. At the end of the 18th century it was recommended for blindness, cataracts, syphilis, strokes and much more, treatments which, as was clear to physicians at the time, were valueless. Gerard (1633) writes: ‘They serve only for the adorning of gardens and garlands, being floures of great beauty’. It is in the buttercup family, Ranunculaceae, all members of which are poisonous. It was recommended, by mouth, for ‘obstinate case of taenia’ (tapeworms). One hopes it was more toxic to the worm than the patient. Flowers with a central disc and radiating florets were regarded as being good for eye complaints under the Doctrine of Signatures. Porta (1588) writes (translated): ‘Argemone [Papaver argemone], and anemone, have flowers of this shape, from this they cure ulcers and cloudiness of the cornea’. There were occupational diseases even before there were words like pneumoconiosis, and Lindley writes that ‘the powder of the root causes itching of the eyes, colic and vomiting, if in pulverising it the operator do not avoid the fine dust which is driven up.’ Photographed in the Medicinal Garden of the Royal College of Physicians, London.

Catharanthus roseus (L.)G.Don Apocynaceae. Madagascar Periwinkle Distribution: Madagascar. It is the source of vincristine and vinblastine, which impair cell multiplication by interfering with microtubule assembly, causing metaphase arrest and are effective medications for leukaemias, lymphomas and some solid tumours. The mortality from childhood leukaemia fell from 100% to 30% once it was introduced - not a drug that could ethically be tested by double-blind trials. These chemicals were initially discovered by investigators in 1958 who were looking for cures for diabetes so tested this plant which was being used in the West Indies to reduce blood sugar levels. There are 70 different alkaloids present in this plant, and some - catharanthine, leurosine sulphate, lochnerine, tetrahydroalstonine, vindoline and vindolinine - lower blood sugar levels. However, the toxicity of this plant is such that this is not a plant to try at home for diabetic management. The vincristine content of the plant is 0.0003%, so two kilograms of leaf are required to produce sufficient vincristine for a single course of treatment for a child (6gm). Fortunately it is a vigorous weed and easy to grow in the tropics. Artificial synthesis has now been achieved. Photographed in the Medicinal Garden of the Royal College of Physicians, London.
