A traditional formula for itchy, inflamed skin

Clear Skin Heat (Xiao Feng San) is a traditional Chinese herbal formula that supports the body during itchy, inflamed skin flare-ups. First recorded in Wai Ke Zheng Zong (True Lineage of External Medicine) by Shen Shi-Gong in 1617, it has long been used when redness, itching, irritation, and oozing affect the skin. It remains a trusted formula for skin patterns where heat, dampness, and irritation combine and make the skin hard to calm.

When to use it

In Traditional Chinese Medicine, practitioners choose Clear Skin Heat when heat and dampness build up in the skin and trigger itching, redness, and flare-ups. The skin may feel irritated, inflamed, or sensitive. Scratching can make it worse and may lead to oozing, swelling, or spreading irritation. Symptoms often worsen with heat, humidity, or repeated scratching.

Many choose this formula for eczema, dermatitis, urticaria, itchy skin rashes, and other skin patterns that flare up with redness, oozing and irritation. It suits those who want support when the skin feels reactive, uncomfortable, and difficult to settle.

Why it stands out

What makes Clear Skin Heat so useful is its balanced approach. It does not only target itching. It also helps calm heat, reduce dampness, and support the skin while it recovers. This makes it a strong choice for natural support when the skin feels red, itchy, irritated, and prone to flare-ups.

Research

Research on Clear Skin Heat has shown promising effects in itch relief, skin inflammation, allergy support, and skin barrier repair. Some studies have also reported changes in markers linked to allergic and inflammatory skin reactions, helping explain its traditional use in eczema, dermatitis, urticaria, and other reactive skin conditions. This gives the formula added relevance for modern skin complaints where flare-ups, irritation, and itching are hard to control.

Important to know

Avoid spicy and greasy foods, seafood, smoking, alcohol, and strong tea during use.
