Which herb is for LU abscess?

• A. Xuan Shen
• B. Sang Ye
• C. Yu Xing Cao
• D. Jie Geng

Answer: (C)

LU abscess is treated in Chinese medicine by clearing heat-toxin and promoting drainage to resolve the pus. Yu Xing Cao (Herba Houttuynia cordata) is the best match because it has a strong action to clear heat-toxin from the lungs and to dissipate phlegm that leads to abscess formation, making it a classic herb for LU abscess and purulent sputum. It’s frequently used specifically for lung and throat abscess due to its targeted ability to drain pus and reduce inflammation in the respiratory tract.

The other herbs don’t address pus drainage in the lungs as effectively. Xuan Shen clears heat and nourishes yin and can be helpful for throat and systemic heat, but it’s not the primary agent for lung abscess drainage. Sang Ye cools lung heat and moistens dryness, again not focused on resolving a pulmonary abscess. Jie Geng guides and transforms phlegm and helps deliver other herbs to the chest, but it doesn’t chiefly drain a lung abscess by itself.
