- Dr. Brian Staiger, PharmDHoly Basil Overview
Holy basil, also known as tulsi (which in Hindi means 'the incomparable one'), is an herb often used in Ayurvedic medicine. It has small, oval-shaped leaves that are typically light green in color, with a slightly bitter/spicy flavor. Holy basil has historically been used to treat a variety of ailments, including stress, anxiety, and respiratory problems. It is also used in traditional Hindu ceremonies.
It is important to note that basil and holy basil are two different varieties of herb. While they are both members of the same plant family (Lamiaceae) and are used for similar purposes, they are distinct varieties with different flavors and uses. For example, basil has a slightly sweeter flavor than holy basil.
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.
