Dantoxicosis of the lower extremities is known as rheumatism in Chinese medicine. It can manifest as edematous erythema with clear borders, burning and pain in one or both lower extremities, enlarged and painful inguinal lymph nodes, some with blisters or hemorrhagic blisters or pustules on the erythema, or even gangrene. Patients may also have systemic symptoms such as fever (38-40°C), chills, nausea, etc. When these systemic symptoms occur in some patients before the redness and pain in the lower extremities appear, they can also be mistaken for a cold. If the disease is recurrent, it is called recurrent dysentery. In addition to herbal treatment to clear heat and dampness, cool the blood and invigorate the blood, there is another important issue, which is Only in this way, it is possible to “eradicate” or not recur for a long time. More than 95% of patients with recurrent dermatophytosis have tinea pedis lesions, which are not taken seriously, and they often think that my feet are not itchy, so why do I have tinea pedis? There are also some who think that if they are cured of tinea pedis, they are going to have other diseases and are unwilling to actively treat tinea pedis. If my feet don’t itch, do I not have tinea pedis? The answer is definitely: “Incorrect”. Tinea pedis lesions can take many forms, including blisters, flaking, cracking, and maceration. When the fungus is infected, people feel local itching of the lesions only when the fungus is more active under proper humidity and temperature conditions, while itching is less pronounced when its activity is suppressed under drier, lower or higher temperatures, but its lesions are still present. Due to the separate or simultaneous existence of the above-mentioned lesion forms, the integrity of the skin is affected, and with scratching during local itching, the skin breaks down, and Streptococcus haemolyticus can easily invade from the broken skin where tinea pedis exists, causing an attack of tinea. The treatment of tinea pedis is based on topical antifungal medications, and its treatment requires, on the one hand, a protracted battle because the temperature and humidity in the Shanghai area are more suitable for the growth of fungi. On the other hand, to treat tinea pedis, it is important to choose not only antifungal drugs, but also different dosage forms according to the different lesion forms present in tinea pedis, such as: dipping type elected with bulking agents, etc. Chinese herbal infusions that clear heat and detoxify, dry dampness and kill insects are also effective for tinea pedis, only then can tinea pedis be cured effectively. After the cold winter season, spring will come, and the temperature and humidity of nature will rise, especially on the “yellow plum” days in Shanghai, which are very suitable for the growth of fungi. This way, you will be farther and farther away from the possibility of tinea.
