Scorpion venom

Scorpion venom was a poisonous substance produced by scorpions. The Tong of the Black Scorpion extracted the venom for capsules. Members were required to ingest the capsule, should their circumstances dictate it so. Ho ingested a capsule given to him by Li H'sen Chang, after he was incarcerated by police.
