Which herb is used to treat lung abscess?

• A. Shi Hu
• B. Bai He
• C. Xian He Cao
• D. Yu Xing Cao

Answer: (D)

When a lung abscess is treated in Chinese medicine, the pattern is hot-heat with pus in the lungs, so the best herb is the one that clears heat and actively drains pus from the chest. Yu Xing Cao (Houttuynia) fits this need well because it clears heat and damp-heat while promoting the drainage of pus, making it particularly effective for pulmonary abscesses where foul-smelling sputum and infection are present. It works by opening the lung passages, reducing swelling, and helping to resolve the purulent accumulation that characterizes the abscess.

The other herbs mainly focus on nourishing or moistening the lungs or addressing different conditions. Shi Hu nourishes yin and clears heat to generate fluids; Bai He moisten the lungs and stop dryness-related cough; Xian He Cao has uses for bleeding and certain damp-heat issues but is not the primary choice for promoting pus drainage from a lung abscess. So Yu Xing Cao stands out as the herb most specifically aligned with draining pus from a lung abscess.
