  • Poisonous to Humans:
    Poison Severity:
    High
    Poison Symptoms:
    Poisoning commonly occurs in horses having inadequate forage, or when the plant is incorporated into hay. All parts of the plant are toxic in both green and dry forms. The toxic component causes a thiamine deficiency (an essential nutrient for central nervous system function and metabolism); clinical signs develop after one to two months of chronic ingestion, and can worsen over a two to three day period. Effects include weight loss, fever, incoordination/ excessive staggering (known as "bracken staggers"), the developement of a wide stance with arched back, severe muscle tremors, inability to get up which could lead to serious injury. Death may occur within one to 2 days of onset if not treated.
    Poison Toxic Principle:
    Thiaminase inhibitor. Milk from cows that have ingested this fern may be toxic to humans.
    Causes Contact Dermatitis:
    No
