Safety & Hazards

Although no specific mention of toxicity for this species has been found, at least some members of this genus are known to contain furanocoumarins, particularly psoralen and angelicin. These compounds can be found in low concentrations in many common foods including citrus fruirs, celery, parsley and parsnips. Ingestion or skin application of these compounds in larger quantities can cause skin photosensitization followed by hyperpigmentation[ 65 Title A Colour Atlas of Poisonous Plants.
