The hyacinth is a bulb flower that blossoms in the spring. The bulb, sap and leaves of the hyacinth contain allergenic components. When these components are touched or ingested, they can cause an allergic reaction.

Hyacinth Itch

The hyacinth bulb, sap and leaves contains an oil that contains many toxic elements. When this oil comes in contact with the skin, it can cause a condition known as “hyacinth itch.”


According to, hyacinth itch can cause a rash, violent itching, inflammation and blisters on the skin. The blisters put the body at risk for further infection.


Hyacinths are also poisonous to humans and cattle, as explained by When consumed, hyacinth bulbs will cause vomiting, diarrhea and stomach cramps.


An allergic reaction to a hyacinth bulb or flower should be treated immediately by washing the area thoroughly with warm water and mild soap. Severe allergic reactions should be referred to a physician for additional treatment.


To prevent an allergic reaction, individuals should wear thick gloves while handling a hyacinth bulb or flower. After handling, the hands should be washed thoroughly and dried with paper towels that can be disposed of.

Kill Blue Hyacinths

Dig the blue hyacinths bulbs out of the ground with a hand trowel. Place the unwanted bulbs in a garbage bag. Missed plant matter can sprout weeks after the initial removal. Use the hand trowel to dig up any new growth and dispose of the plant matter in a garbage bag. Wear chemical-resistant rubber gloves. Mix concentrated broad-leaf herbicide with the appropriate amount of water as stated on the usage instructions. Add the mixture to a garden sprayer. Alternatively, purchase a nonconcentrated herbicide. Saturate the foliage and flowers of the blue hyacinths with the herbicide. Refrain from spraying other plants as the herbicide will damage other vegetation such as grass and flowers. Wait two weeks before mowing the area again.
