Health authorities in San Francisco have warned against consuming herbal tea from a Chinatown shop after two people took critically ill.
San Francisco Department of Public Health advised against consuming tea from Sun Wing Wo at 1105 Grant avenue. The alert comes after two separate instances of a man and a woman developing acute symptoms of poisoning after consuming herbal tea bought from the store were reported. Lab tests revealed the tea contained aconite, a plant-based toxin known to cause fatalities.
