IMPORTANT NOTE 13 JULY 2019: Gentian violet has been removed from our treatment suite due to a health warning. Please read and do not use gentian violet.
Use a very thin layer of gentian violet (1% mixture in 10% alcohol, dilute to 0.5%) every day for seven days on the head of the penis using a cotton bud or paint brush. Get into every nook and cranny possible, especially down into foreskin crevices and creases, but avoid putting gentian violet into your urethra. Allow to air dry, then go about your day.
You do not need to paint the shaft of your penis or your scrotum, as the biofilm potential of these areas is comparatively low. (You can if you want to though.) You may wish to use disposable gloves to apply the solution because explaining why you have purple hands may get awkward.
Gentian violet is an excellent antibacterial, antifungal, and has biofilm-busting capabilities. We think it’s worth a try, even before using other treatments, even though it’s messy – it’s cheap and might just do the trick with a short treatment.
Do not drown your penis in gentian violet (like soaking it in a condom full), as irritation can occur that can result – with prolonged use – in ulcerations. These ulcers are terrible and painful and to be avoided at all costs – just a thin layer painted on with a paintbrush or cotton tip is perfect.
Avoid putting gentian violet into your urethra, as the sensitive mucous membranes may not like it much. If you think you have urethral biofilms/colonisation, do oral treatments with enzymes too.
Warning! Gentian violet stains! For a week! So if you have a hot sex date where comedy is not on the cards, avoid this treatment until you have a week spare, plus a week after for it to wash off.
Warning #2! Any irritation, stop using gentian violet immediately and wipe it off using rubbing alcohol (it is alcohol soluble, not water soluble), then rinse with water and a mild soap, and then apply a soothing oil like coconut or vitamin E.
What is gentian violet?
Gentian violet is a coal-tar derivative, and the instructions for this extraction are to be found in industrial chemistry textbooks. It shouldn’t necessarily be considered ‘natural’, as it may come from coal, which is natural, the extraction method isn’t exactly natural.
Gentian violet is a very old-school type of treatment that lost favour when antibiotics came along. Gentian violet is very effective at killing fungus and gram-positive bacteria, and having some action against gram-negative bacteria. Gentian violet is used in Gram staining – the method developed by Hans Gram for identifying bacteria.
Where to find gentian violet
You can ask at your local pharmacy (it might be behind the counter) or buy online. Some supermarkets may stock it. Each country will differ in availability, so ask around. Don’t just ask anyone at a store – make sure you ask someone who can look it up in the system, because most people don’t know what this is.
