Heartleaf (Houttuynia Cordata)
어성초 · 魚腥草
Also known as: Houttuynia Cordata, Eodoksae
What it actually does
A traditional Korean herbal extract commonly used in cosmetic formulations intended to help calm the look of reactive, warm-feeling skin and support a more balanced-looking complexion.
How to use it
Use as a toner, essence or serum morning and night, especially when skin feels hot, itchy or reactive.
The science, in plain English
A traditional Korean herb (eodoksae) containing quercetin, studied at a cosmetic level for helping calm the visible look of redness and support the barrier.
Myth vs reality
Being gentle does not mean it works instantly — any visible change is generally associated with weeks of consistent use, not a single application.
Limitations of the evidence
Evidence is mostly limited to laboratory and small cosmetic studies of its quercetin content; it is not a substitute for medical treatment of active skin conditions.
Who may need extra caution
People with active or diagnosed skin conditions should consult a dermatologist rather than rely on this ingredient alone.
