ADDISON COUNTY — Michael O’Neill had a run-in with a colorful but noxious weed last summer when he saw the plant and, out of curiosity, smelled and touched its tall, green stems and yellow blossoms. Unfortunately, the Shoreham man suffered an adverse reaction — itching and mildly blistering skin — but it was not bad enough for him to seek medical help for the condition.
Earlier this summer, however, O’Neill accidentally brushed his hand across one of the plants and this time suffered severe blistering.
