Commonly known as hellebores /ˈhɛlɨbɔərz/, members of the genus Helleborus comprise approximately 20 species of herbaceous or evergreen perennial flowering plants in the family Ranunculaceae, within which it gave its name to the tribe of Helleboreae. Many species are poisonous. Despite names such as "Christmas rose" and "Lenten rose", hellebores are not closely related to the rose family (Rosaceae).
In the early days of medicine, two kinds of hellebore were recognized: black hellebore, which included various species of Helleborus, and white hellebore, now known as Veratrum album, which belongs to a different plant family, the Melanthiaceae.[9] Although the latter plant is highly toxic, containing veratrine and the teratogens cyclopamine and jervine, it is believed to be the "hellebore" used by Hippocrates as a purgative.
"Black hellebore" was used by the ancients in paralysis, gout and other diseases, more particularly in insanity. "Black hellebore" is also toxic, causing tinnitus, vertigo, stupor, thirst, a feeling of suffocation, swelling of the tongue and throat, emesis (vomiting), and catharsis, bradycardia (slowing of the heart rate), and finally collapse and death from cardiac arrest.[10] Although Helleborus niger (black hellebore) contains protoanemonin,[11] or ranunculin,[12] which has an acrid taste and can cause burning of the eyes, mouth and throat, oral ulceration, gastroenteritis and hematemesis,[13] research in the 1970s showed that the roots of H. niger do not contain the cardiotoxic compounds helleborin, hellebrin, and helleborein that are responsible for the lethal reputation of "black hellebore". It seems that earlier studies may have used a commercial preparation containing a mixture of material from other species such as Helleborus viridis, green hellebore.
Watercolor (American English) or watercolour (Commonwealth and Ireland), also aquarelle from French, is a painting method in which the paints are made of pigments suspended in a water-soluble vehicle. The term "watercolor" refers to both the medium and the resulting artwork. The traditional and most common support for watercolor paintings is paper; other supports include papyrus, bark papers, plastics, vellum or leather, fabric, wood, and canvas. Watercolors are usually transparent, and appear luminous because the pigments are laid down in a relatively pure form with few fillers obscuring the pigment colors. Watercolor can also be made opaque by adding Chinese white. In East Asia, watercolor painting with inks is referred to as brush painting or scroll painting. In Chinese, Korean, and Japanese painting it has been the dominant medium, often in monochrome black or browns. India, Ethiopia and other countries also have long traditions. Fingerpainting with watercolor paints originated in China.
