Which topical herb could you apply for oozing sores?

• A. Ru Xiang
• B. Di Yu
• C. Mo Yao
• D. Bai Zhi

Answer: (B)

When a sore oozes, the problem is damp-heat with discharge from the skin, so the best topical approach is something that dries dampness and stops the discharge while supporting healing. Di Yu has strong astringent and cooling properties that clear heat and dry dampness in skin lesions, making it particularly effective for oozing ulcers and damp, weeping sores when applied externally. It helps seal the lesion and reduce exudate, which is exactly what you want in this scenario.

Other wound-health herbs like Ru Xiang (frankincense) and Mo Yao (myrrh) promote healing, reduce swelling, and improve blood flow, but they’re not as specifically targeted to stopping persistent discharge. Bai Zhi is more about addressing wind-heat and superficial lesions rather than controlling damp-heat with ongoing oozing. So Di Yu fits the goal of stopping the oozing while supporting healing.
