Yu Xing Cao鱼腥草
Houttuyniae Herba · Houttuynia · Fish Mint
Overview
Fish mint — named for the sharp fishy smell of the fresh plant — is the first herb reached for when there is heat with pus in the Lung. Acrid and slightly cold, it clears toxic heat, drains pus, and also frees hot painful urination. The part of the herb that does the work is volatile, so it goes into the pot late and is not boiled long.

Cautions
Cold in nature: not for deficiency-cold patterns, chronic watery diarrhea, or the pale sunken type of sore. Prolonged boiling destroys the aromatic fraction that carries the effect. Injectable Houttuynia preparations — which are not part of ordinary herbal practice — have caused serious allergic reactions and are restricted in China; only the decocted or fresh herb belongs in a prescription.
