The condition known as "fox urine thorn" (Huniaoci) is said to occur when urine from wild foxes lands on thorny plants. Contact with these plants often injures human fingers or toes, causing swelling, pain, and heat. Sometimes the toxic qi remains localized without spreading. However, those suffering from this toxicity may not necessarily have been injured by fox urine thorns; it is likely due to malignant toxic vapors. Hence, medical texts also refer to it as "malignant thorn toxin" (Ecici Du).
