Two people are critically sick in San Francisco after drinking tea from the same Chinatown herbalist.
The city’s Department of Public Health said on Friday that the tea leaves bought at Sun Wing Wo Trading Company contained the plant-based toxin Aconite.
Each person grew weak then had life-threatening abnormal heart rhythms that required resuscitation and intensive care.
Aconite, also known as monkshood, helmet flower and wolfsbane, is used in Asian herbal medicines. But it must be processed properly to be safe.
