“…Ammi majus or Bishop's weed has been recommended in the Ebers papyrus (1'500 BC) to be rubbed directly into the skin or taken orally and then to stand naked in the sun (2) Europe. There have been experiments in Switzerland with selective spectra of UV-light [61]. In Germany studies with topical photosensitizers have been performed [62,63].…”

Background: The history of psoriasis, remains highly speculative for the time before Willan (1757Willan ( -1812, and can be reliably assigned only for the last 200 years. Terms such as "Leprosy", "Impetigo" and "Psora" have been used in the centuries before. Hebra (1806-1880) gave a morphological and nosologic definition, in which also the histopathology appearance was taken into account. In the early 20th century, it was the biochemistry and histochemistry, which provided new insights. In the second half of the 20th century, immunocytochemistry and immunology shed some light on the pathogenetic processes of the disease. At the end of the 20th and at the beginning of the 21st century, it is the triumph of genetics and immunology, which have opened new therapeutic possibilities due to the interesting insights into the pathogenesis of psoriasis. However besides the new therapeutic modalities, which harbor some health and some economic threats, classical approaches still remain valuable tools.

“…Certain plants may induce a form of photosensitivity reaction (van Dijk 1963, van Dijk & Berrens 1964, Kuske 1940, Pathak et al 1962). The first report in the literature dates back to 1926, when Oppenheim called this phenomenon "dermatitis bullosa striata pratensis" (van Dijk 1963).…”

Phytophotodermatitis An experimental study using the chamber method

Contact Dermatitis

Experimental phytophotodermatitis was produced using crushed leaves from the gas plant, Dictamnus albus. The tests were made using the chamber method and irradiated with ordinary black light tubes. An occlusion time of not less than 30 min was needed to give a phototoxic reaction in all test subjects. An occlusion time 30-120 min gave the optimal results, but contact for 24 h produced only weak and inconsistent reactions. The phototoxic substance was readily absorbed into the skin within 10-15 min. The phototoxic tendency already began to disappear within 30 min after the tests were removed. UVA energy of 0.3 J/cm2 was enough to evoke a phytophotoreaction in all of the test subjects when other conditions were optimal. The reactions were enhanced by adding water to the test sites. Deep-freezing of the plant material did not destroy the phototoxicity within a 4-month period.
