Can Euphorbia humifusa be used to treat skin itching?

Under normal circumstances, Euphorbia humifusa (Di Jin Cao) has certain therapeutic effects on some cases of skin itching. However, medication use should always follow medical advice. The detailed analysis is as follows:

In traditional Chinese medicine (TCM), Euphorbia humifusa possesses properties that clear heat and detoxify, cool the blood to stop bleeding, and promote diuresis to resolve jaundice. From a TCM perspective, skin itching may be caused by various factors, such as internal accumulation of damp-heat in the skin or wind generated from blood heat. The heat-clearing, detoxifying, and dampness-resolving effects of Euphorbia humifusa help eliminate damp-heat pathogens from the body, reducing irritation of the skin and thereby alleviating itching. Its ability to cool the blood also helps relieve itching caused by blood heat, promoting normal blood circulation and reducing discomfort.

Modern pharmacological studies have shown that Euphorbia humifusa contains various chemical components such as flavonoids and tannins, which exhibit antibacterial, anti-inflammatory, and antioxidant activities. When skin itching is caused by bacterial or fungal infections or inflammatory reactions, the antibacterial and anti-inflammatory properties of Euphorbia humifusa can inhibit the growth and reproduction of pathogens and reduce inflammation, thus relieving itching. Its antioxidant effects help neutralize free radicals, protect skin cells from oxidative damage, maintain normal skin physiological functions, and reduce the occurrence of itching.

However, Euphorbia humifusa is not effective for all types of skin itching. For example, its effect may be limited in cases caused by allergies, dry skin, or endocrine disorders. Additionally, caution is required when applying Euphorbia humifusa externally via washing or topical application if there is broken skin, ulcers, or open wounds, as it may lead to infection or further irritation, potentially worsening the condition.

When using Euphorbia humifusa to treat skin itching, care should be taken and treatment should be conducted under the guidance of a qualified healthcare professional. Patients should also maintain healthy lifestyle and dietary habits to support overall skin health.
