Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Digoxin-like toxicity cause by the Chinese herbal medicine, chan su

    Ingestion of chan su, a Chinese topical anesthetic and purported aphrodisiac, can cause a dangerous reaction similar to digoxin toxicity.

    Several years ago, the New York City Poison Control Center reported 4 men who died from abnormal heartbeats. Each person had measurable levels of “digoxin” in their blood. However, digoxin had not been prescribed for them.

    It turns out, they were taking chan su, an aphrodisiac and sold under the name, dan chen, “Love Stone,” “Black Stone,” “Stone” and “Rock Hard.” Other aliases are listed in an earlier post.

    Details and implications about the toxic reaction to chan su are discussed in an article I wrote several years ago.
