Royal Blood-Fresh

Royal Blood-Fresh is a traditional Korean medicine health supplement derived from soybeans. It is manufactured in North Korea and is the most famous product sold by the North Korean company, Pugang [Pharmaceutic Company|Pugang Pharmaceutic].
It is marketed as a "blood purifier" and a preventative against deep-vein thrombosis. It is marketed to foreigners during Air Koryo flights and has been sold at Pyongyang Gwan, a North Korean restaurant in Hanoi, Vietnam. It has been dismissed outside of North Korea as a non-scientific "miracle cure".
In 2017, three Russian nationals were arrested in South Korea for selling North Korean drugs, which included Royal Blood-Fresh, Kumdang-2, and Neo-Viagra-Y.R.
