    Toxic Components Of Agapanthus

    Agapanthus plants contain various toxic compounds, including glycosides, saponins, and substances known as lycorine alkaloids. These substances are primarily found in the plant’s roots, bulbs, and sap. While beautiful to look at, caution is necessary when growing Agapanthus, especially if you have young children or pets. The sap of Agapanthus plants contains natural irritants, primarily oxalate crystals, which may cause skin irritation upon contact in some individuals. Skin rashes, itching, and redness are common symptoms, but severe reactions are relatively rare [2].
