Gentian Violet: A 19th Century Drug Re-Emerges in the 21st Century
Gentian violet (GV) has a long and varied history as a medicinal agent. Historically used as an anti-bacterial and anti-fungal, recent reports have shown its utility as an anti-typranosomal, anti-viral and anti-angiogenic agent.
Information About Crystal Violet From Wikipedia
Crystal violet or gentian violet (also known as methyl violet 10B or hexamethyl pararosaniline chloride) is a triarylmethane dye used as a histological stain and in Gram's method of classifying bacteria. Crystal violet has antibacterial, antifungal, and anthelmintic properties and was formerly important as a topical antiseptic. The medical use of the dye has been largely superseded by more modern drugs, although it is still listed by the World Health Organization.
The name gentian violet was originally used for a mixture of methyl pararosaniline dyes (methyl violet), but is now often considered a synonym for crystal violet. The name refers to its colour, being like that of the petals of certain gentian flowers; it is not made from gentians or violets.
Information On Gentian Violet From PubChem
Crystal violet is an organic chloride salt that is the monochloride salt of crystal violet cation. It has been used in creams for the topical treatment of bacterial and fungal infections, being effective against some Gram-positive bacteria (notably Staphylococcus species) and some pathogenic fungi (including Candida species) but use declined following reports of animal carcinogenicity. It has also been used for dying wood, silk, and paper, as well as a histological stain. It has a role as a histological dye, an antiseptic drug, an antibacterial agent, an antifungal agent and an anthelminthic drug. It contains a crystal violet cation. Hexamethyl-p-rosaniline chloride is a green to dark green powder.
Gentian Violet is a blue, aniline-derived dye with antifungal and antimitotic properties. Gentian violet (GV) dissociates into positive (GV+) and negative ions (Cl-) that penetrate both gram-positive and gram-negative bacterial cells. The GV+ ions interact with negatively charged components of the bacterial cell wall including lipopolysaccharide, peptidoglycan and DNA. This agent is also a mutagen and mitotic poison. GV elicits a photodynamic action mediated by a free-radical mechanism. Furthermore, this agent dissipates the action potential on prokaryotic or eukaryotic membranes by inducing permeability, thereby leading to respiratory inhibition and subsequent cell death.
Crystal Violet/ Gentian Violet Uses
Basic violet 3 is a color additive that functions as nonoxidative hair colorants. Under the US Food and Drug Administration (FDA) voluntary cosmetic registration program (VCRP), manufacturers provide information on their use of individual cosmetic ingredients as a function of product type. No current uses of any of these ingredients are reported in the VCRP. Basic Violet 3 also is used as an acid-base indicator (pH 0, green; to pH 2.0, blue), a bacteria stain, and an antiseptic. It is classified as a class I medical device for its use as a dye and stain.
Crystal violet is used in the office equipment industry for the production of indelible pencils /SRP: former/, for making stamping and hectographic inks, and for dyeing paper. The color strength in hectographic coloring matter is particularly high if crystal violet is present as the nitrate. The grain hardness of crystal violet or methyl violet is lowered by crystallizing the dye in the presence of poly(ethylene glycol). Crystal violet can also be used as a component of navy blue and black dyes for polyacrylonitrile fibers. Ink jet inks containing crystal violet and di(ethylene glycol) butyl ether have high antibacterial activity.
Acid-base indicator, alcohol denaturant, biological stain, textile dye. Used industrially to prepare inks, and to both dye and surface-coat paper. Principal use as a stain for bacteria (Gram's stain), chromatin, Holzer's stain for neuroglia. Veterinary drug for the treatment of ornamental fish infected with the parasitic protozoa Ichthyophthirius multifiliis.
Crystal Violet First Aid Information From PubChem
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. If symptoms such as redness or irritation develop, IMMEDIATELY call a physician and be prepared to transport the victim to a hospital for treatment. INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing. INGESTION: DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. Be prepared to transport the victim to a hospital if advised by a physician. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport the victim to a hospital.
