Athlete's foot or tinea pedis is a parasitic fungal infection of the epidermis of the foot. It is typically caused by a mold (but in some cases a yeast) that grows on the surface of the skin and then grows into the living skin tissue itself, causing infection. It usually occurs betwwen the toes, but in severely lasting cases may appear as an extensive "moccasin" pattern on the bottom and sides of the foot. Tinea pedis is estimated to be the second most common skin disease in the United states, after acne.
Athlete's Foot causes scaling, flaking, and itching of the affected skin and areas surrounding. Blisters and cracked skin may also occur, leading to exposed raw tissue, pain, swelling and inflammation. The infection can be spread to other areas of the body, such as the armpits, knees, elbows, and the groin, and usually is called by a different name once it spreads (such as tinea cruris, or jock itch for an infection of the skin or groin area).
One ingredient of Dr. Ku's has an anti-fungal property that has been shown to be very effective in treating Athlete's Foot. The anti-histamine property of this medicinal oil also reduces the itch and thus allows the lesions to heal more quickly because if it doesn't itch you don't want to scratch!
