Introduction
When dermatitis is caused by internal heat toxicity and damp-heat, manifesting symptoms such as redness, swelling, itching, and exudation of the skin, Houttuynia cordata, with its properties of clearing heat, detoxifying, and promoting diuresis, may help alleviate the condition. Under a doctor's guidance, moderate consumption might assist in eliminating damp-heat pathogens from the body and reducing inflammatory responses in the skin; however, it should be used in conjunction with standard medical treatment. It should not be taken if the patient's condition does not match the indicated syndrome pattern or if the patient has an allergy to it.
Generally, patients with dermatitis can consume Houttuynia cordata (fish mint) if their syndrome pattern matches and they are not allergic to it. However, if their syndrome pattern does not match or if they are allergic, consumption should be avoided. If any abnormalities occur, prompt medical attention is recommended. Detailed explanations are as follows:
When dermatitis is caused by internal heat toxicity or damp-heat, presenting symptoms such as redness, swelling, itching, and exudation of the skin, the heat-clearing, detoxifying, and dampness-resolving effects of Houttuynia cordata may help alleviate the condition. Under a doctor's guidance, moderate consumption may assist in eliminating pathogenic damp-heat from the body and reducing inflammatory skin reactions, although it should be used alongside standard medical treatments.
If a dermatitis patient has a constitution characterized by spleen-stomach deficiency cold, consuming Houttuynia cordata may burden the spleen and stomach, potentially causing discomfort such as abdominal pain and diarrhea, which could negatively impact overall health and impede recovery from dermatitis. If the patient is allergic to Houttuynia cordata, allergic reactions may occur immediately after consumption, leading to increased rashes, worsened itching, or even severe symptoms such as throat swelling, endangering health.
Prior to consuming Houttuynia cordata, patients with dermatitis must consult a doctor to determine whether their syndrome pattern is suitable and to assess their tolerance to the herb. Self-administration without medical advice should be strictly avoided to prevent worsening of the condition or triggering other health problems.
