Jock itch is essentially an infection of the skin in the groin area, sometimes extending to the inner thigh area, the genitals, and the area of the anus. I am not aware of the remedy that you have mentioned, but there are numerous other ways to handle this infection. First, of course, you need to understand the causes of the infection. Jock itch, also known as tinea cruris, is usually a fungal infection, although sometimes secondary bacterial infections can also develop. The fungus responsible is usually one that is normally present on the body. However, due to certain factors, the fungus gets out of hand and multiplies, leading to an infection and all the accompanying symptoms such as itching, burning, inflammation, discoloration of the skin, as well as peeling and flaking of the skin. In most cases, the factor responsible is insufficient hygiene. The groin area tends to be damp a lot of the time, and fungi thrive in moist conditions. Tight clothing made of synthetic material tends to trap sweat, and also rubs against the skin itself, worsening the problem. In some cases, a low immune system may also contribute to the infection - due to poor functioning of the immune system, the body may be unable to keep fungal growth under control.
A major part of treating and preventing jock itch involves keeping the groin area clean and dry at all times. You should wear natural fibers such as cotton, and ensure that clothes and underwear are not too tight. Change your clothes and underwear daily, and perhaps more than once a day, if you tend to sweat a lot or work in hot, humid conditions. If you wear a jock strap, avoid using it for long stretches at a time, and make sure that it is always clean. Body hygiene is of course important too - wash your genitals and the entire groin area thoroughly every day, preferably several times a day. After each wash, dry the area thoroughly before wearing your clothes. It may also help to use an over the counter anti fungal powder every time you wash yourself.
If this does not bring about any improvement within ten days, you should consult a doctor. In some cases, medical treatment may be needed to successfully get rid of jock itch. This usually consists of topic antifungals, but it may sometimes include glucocorticoid steroids to reduce the irritation.
