Houttuynia

Houttuynia (Yu Xing Cao) is a standout herb in Chinese medicine, traditionally used to clear heat, resolve toxin, disperse lung congestion, and support urinary and digestive balance. In classical Chinese herbal medicine it is used to address patterns of heat, dampness, and stagnation that impair immune function and microbial harmony.

Modern herbalism has taken a renewed interest in Houttuynia for its broad-spectrum antimicrobial activity, including its effects on gram-negative bacteria, intracellular pathogens, and biofilm-forming microbes.

Its naturally occurring flavonoids, alkaloids, and volatile oils, such as quercetin, rutin, houttuynin, and methyl-n-nonyl ketone, are studied for their ability to influence microbial balance, modulate inflammatory pathways, and support immune regulation.

Because of these actions, Houttuynia has become a key herb in integrative protocols addressing the complex microbial terrain often associated with Lyme disease and its co-infections, particularly Bartonella. We value Houttuynia for its potential to:

• Encourage clearing of infection and toxin from tissues

• Support healthy immune modulation

• Influence microbial load and balance

• Assist with biofilm-disruption strategies

• Promote lymphatic and respiratory clarity

• Support vascular integrity (traditionally relevant in Bartonella patterns)

Houttuynia is s a powerful ally for those navigating layered microbial challenges and seeking a plant-based approach to restoring internal harmony and resilience.
