Black Hellebore Overview
Black Hellebore (Helleborus niger), also known as Christmas Rose, is a perennial flowering plant native to Europe. Despite its toxic nature, it's admired for its striking white or pale pink flowers that often bloom in winter, hence the name "Christmas Rose." However, its ingestion can be poisonous and has been used historically in herbal medicine with caution due to its potent compounds.
Foscarnet Overview
-
Foscarnet injection is used alone or with ganciclovir (Cytovene) to treat cytomegalovirus (CMV) retinitis (an eye infection that can cause blindness) in people who have human immunodeficiency virus (HIV) infection. Foscarnet injection is also used to treat herpes simplex virus (HSV) infections of the skin and mucus membranes (mouth, anus) in people whose immune system is not working normally and when treatment with acyclovir did not help. Foscarnet is in a class of medications called antivirals. It works by slowing the growth of CMV and HSV. Foscarnet controls CMV retinitis and HSV infections of the skin and mucus membranes but does not cure these infections.
