- 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).
