Elaeocarpus aculeatus injury (referred to as "evil thorn" or toxic prickly wound in ancient texts), occurs when the urine of a venomous snake contaminates plants. Upon contact with human skin, it feels like being pricked by a needle, followed immediately by swelling, pain, and muscle necrosis. If it affects the hands or feet, it may lead to the sloughing off of finger or toe joints.
Formula for treating Elaeocarpus aculeatus injury:
Vulpis ossis foxis cinis (Fox bone ash) (1 fen)
Mel cruda (Raw honey) (a small amount)
Allii fistulosi bulb (Hushu / Chinese onion) (a small amount)
Grind the above ingredients together. Seal with paper pasted with vinegar-flour paste for three days. The thorn will naturally emerge.
