Fleshy growths resembling thorns growing between the toes are called "flesh thorns" (Rouci, a type of corn or callus). This condition arises from wearing tight boots and socks, causing friction between the little toe and adjacent toes.

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).
Prescription for treating injuries from fox urine thorns with swelling and pain:
Melt Beeswax (Huangla) into liquid. Check that the temperature is appropriate, then drip onto the swollen and painful area.
Prescription for treating injuries from fox urine thorns causing day-and-night dry pain and insomnia:
Take the stems, leaves, and roots of Taraxaci Herba (Pugongcao, Dandelion). Crush and squeeze to obtain the white juice. Apply frequently for cure.
Another prescription:
Take good-quality Fermented Soybean (Douchi Xin), chew thoroughly, and apply to the affected area. Inspect the soybean after a short while; hairs should appear. If none are seen, chew more soybeans and apply again. The condition resolves once all hairs are expelled.
Another prescription:
Grind Semen Pruni Armeniacae (Xingren, Apricot Seed) finely. Boil for one or two boils. While hot, soak the stung area. Change frequently.
Prescription for treating injuries from fox urine thorns with unbearable pain:
Take Radix Trichosanthis (Gualugen, Trichosanthes Root) and Fermented Soybean (Xiangchi) in equal parts. Pound into a cake and apply to the area. Replace when dry.
