What is the primary effect of exposure to contactant allergens from toxic plants such as poison ivy?

In what way do ingestant allergens differ from contactant allergens?

Which of the following is NOT classified as a type of allergen?

Allergen Types

Inhalant Allergens: Substances that can trigger allergic reactions when inhaled, often found in pollen, mold spores, and pet dander.
Ingestant Allergens: Compounds that cause allergies through consumption, such as certain foods like nuts, seafood, or dairy products.
Injectant Allergens: Allergens introduced into the body through bites or stings, like those from insects or certain plants.
Contactant Allergens: Substances causing allergic reactions upon skin contact, including certain plants like poison ivy.

Dermatitis and Irritation

Dermatitis can occur due to direct or indirect contact with irritants, often leading to skin reactions.
Plants such as poison ivy are notable for causing contact dermatitis through their sap.

Toxic and Hallucinogenic Plants

Historical knowledge of plant toxicity has evolved through both study and experience.
Many plants produce chemical compounds harmful to humans and other organisms, leading to various reactions based on exposure (direct contact or ingestion).

This quiz explores different types of allergens, including inhalant, ingestant, injectant, and contactant allergens. It also addresses dermatitis and skin irritation caused by direct or indirect contact with plants, such as poison ivy. Test your knowledge on these important topics related to allergy and skin health.
