About Yin Xing Cao / Fishy Smelly Herb

Houttuynia is considered an invasive weed in the United States and Australia.  I find this a bit ironic, as Houttuynia for us is a bit difficult to obtain.  

An interesting side fact, Houttuynia is one of the ingredients in the foot pads which are placed on the feet at night to remove toxins.

Houttuynia is one of the herbs which is used when Lyme disease is present. Houttuynia  is anti-inflamatory, antipyretic, antitussive, anti-viral, anti-microbial, detoxicant, diuretic, and refrigerant. Formulas for flu, particularly the Avian flu are intergrading houttuynia with traditional formulas such as Jade Screen Formula (with astragalus as a major constituent). Formulas may includes additional herbs which benefit the lungs: the anti-infection herb houttuynia, the yin nourishing glehnia, and the congestion-alleviating centipeda (an herb, not to be confused with the insect centipede).

Among the important pharmacological activities reported for Yu Xing Cao in bulk herb form includes, anti-mutagenic, anti-cancer, adjuvanticity, anti-obesity, hepatoprotective, anti-viral, anti-bacterial, anti-inflammatory, free radical scavenging, anti-microbial, anti-allergic, anti-leukemic, chronic sinusitis and nasal polyps activities. 


In Traditional Chinese Medicine Houttuynia is used to combat: sinusitis and chronic ear infections, lyme dysease and bartonella, fevers, indigestion, dysentery, stomach cramps, constipation, stomach ulcers, and dysuria.

The literal translation of Yu Xing Cao is "fishy-smelling herb". Fresh cut stems have a strong odor, but the smell disappears when dried. Houttuynia has been used in Traditional Chinese Medicine to clear heat and toxins, and to reduce swellings and abscesses.

The active components in Houttuynia myrcene, limonen, alpha-pinene, camphene, sterols, polyphenols, flavonoids, and querticin.
