Plant extract
What is Houttuynia cordata extract?
Houttuynia cordata extract is a water based extract of the herb Korean labels call eoseongcho. It goes into the water phase as a botanical additive, and ingredient lists name it after either the plant or the INCI entry. An extract is a mixture rather than one defined compound, so what is actually in it depends on how the supplier made it.
