South Korean officials have just seized thousands of illegally smuggled drug capsules, filled with the powdered flesh of dead babies.

An investigative report last year revealed some Chinese hospitals who illegally sold dead fetuses and placenta to manufacturers. Korean Customs Service describe the harrowing process wherein the baby’s bodies are chopped into smaller pieces, dried on stoves, and later turned into powder.

These drugs, disguised as stamina boosters are believed to contain medicinal properties. There have been multiple smuggling attempts to South Korea since last year; officials have since seized over 17,000 capsules. Upon further inspection, these capsules of dried human flesh contained bacteria and other harmful ingredients. But so far, no official sicknesses have been reported from ingesting the capsules.

Chinese media have identified the Northeastern province of China as the main source of these drugs. One capsule sells for $35 (40,000 won) in Korea.
