Fake or unlawfully produced medication and natural supplements are becoming an improving problem throughout the world. Internet revenue make simpler submission and transaction of these falsified medication. Here we review on a Vietnamese natural medication, which was promoted for therapy of rheumatic illness from a spiritual Vietnamese healbot.
