Three documented human cases of convulsions from hyssop oil at low oral doses (15 to 30 drops). A 6-year-old had a seizure after ingestion for asthma. An 18-year-old woman lost consciousness and convulsed after taking 30 drops for a cold.
The common hyssop oil chemotype (pinocamphone CT) must be regarded as a hazardous oil due to its convulsant potential, particularly orally.
