Tea Brewed From Angel’s Trumpet Causing Hospitalizations In Kids
Toxicity reports are re-emerging in southern California this week after a dozen hospitalizations of kids using teas made from a fragrant flowering plant called Angel’s Trumpet.
A tea made from the plant is used to produce hallucinations, but they can progress to extremely unpleasant experiences. Moreover, Angel’s Trumpet can be deadly, accelerating the heart rate and causing fatal cardiac rhythmic disturbances and bronchoconstriction that can trigger asthma attacks in sensitive individuals.
Angel’s Trumpet is one of a series of plants in the Brugmansia genus that make a variety of muscarinic cholinergic antagonists such as atropine (dl-hyoscyamine, pictured to the right) and scopolamine (l-hyoscine). These compounds are also known chemically as tropane alkaloids or belladonna alkaloids, the latter derived from their classical isolation from Atropa belladonna. The belladonna name derives from the use of eye drops made from the plants that prevent constriction of the pupils (mydriasis), back when the size of a woman’s pupils was a sign of beauty and arousal.
The tropane alkaloids are ubiquitous in plants and fungi and act as classic hallucinogens when used in high doses. Their legend goes back to witches brews, which we discussed here, and beyond. A wonderfully colorful history of tropane alkaloids by Robert S. Holzman of Children’s Hospital and Harvard Medical School was offered in this free 1998 paper in the journal Anesthesiology (1998; 89:241-249).
However, the aftermath of Angel’s Trumpet use isn’t all fun and games. In cases like these, I like to turn to the Erowid site, a respected, user-supported site that offers non-judgmental information on plant-derived and synthetic psychoactive agents. The Erowid Experience Vault has several descriptions of the use of Angel’s Trumpet but this one is the most detailed and representative of the downsides of this plant. (Note that the colloquial term for Angel’s Trumpet in Australia is sometimes “Tree Datura,” although Brugmansia is a closely-related but distinct genus from Datura within the Solanaceae family.)
I also came across a poorly-documented 2003 news article cited a German teenager cutting off his penis and tongue with garden shears after using Angel’s Trumpet.
While I’m NOT a physician, emergency personnel stumbling upon this post would do well to note that physostigmine or pilocarpine are typical antidotes for anticholinergic poisonings with Angel’s Trumpet, Atropa, Datura, and other similar plants that cause dilated pupils with loss of accommodation, xerostomia (dry mouth), and tachycardia.

From eMedicine:
Remember common signs and symptoms with the mnemonic, “red as a beet, dry as a bone, blind as a bat, mad as a hatter, and hot as a hare.” The mnemonic refers to the symptoms of flushing, dry skin and mucous membranes, mydriasis with loss of accommodation, altered mental status (AMS), and fever, respectively.
If you are a kid screwing around with this stuff and have asthma, or see an asthmatic friend screwing around with this stuff, quickly use an albuterol inhaler and call 911.
NOTE: The photo shown here of Brugmansia “Feingold” is from a Wikimedia Commons gallery of Angel’s Trumpet if you’re in need of identifying the plant after treating a poisoning case.
