Podophyllum is not suitable for the treatment of blistering foot odor, but it is effective in the treatment of keratosis pilaris and oedema. The ingredients of Footlight San itself contain salicylic acid and benzoic acid, both of which are irritating and can easily lead to skin erosion at the blisters on the feet, and the erosion can easily become infected, leading to further aggravation of the condition. Foot fungus is a disease caused by fungal infection, and patients can have symptoms such as itching and peeling of the skin on the feet. In the case of blistering foot odor, the main manifestation is the appearance of blisters between the toes and plantar areas, some of which may fuse into large blisters and may be accompanied by significant itching. Patients should seek medical attention as soon as possible and use non-irritating creams for application under the guidance of a doctor, such as antifungal miconazole, ketoconazole, terbinafine, etc. Pay attention to insisting on using the creams because stopping them when blistering foot odor has not yet recovered may lead to recurrent attacks and other problems that cannot be cured. If a bacterial infection occurs in the patient’s feet due to the rupture of blisters, it is also necessary to follow medical advice and use antibiotics for treatment. In normal life, pay attention to personal foot hygiene, dry the water between the toes after bathing and keep the feet dry. Change clean shoes and socks regularly, wear socks and shoes with good breathability, and also avoid sharing slippers and towels with others. If the skin is broken, try not to scratch or scald it.
