Basil is non-toxic in small amounts but may cause mild vomiting or diarrhea if eaten in larger quantities. Avoid pesto, herb mixes, and packaged pastes — they typically contain garlic, cheese, salt, or oil.
Basil is an aromatic herb with tender green leaves on square stems, available in sweet, Thai, and purple varieties. Flavor ranges from clove-like to peppery.
Basil is used fresh or dried in Italian cooking, Southeast Asian dishes, and seasoning blends. It's sold in bunches, clamshells, or as potted plants, and as dried flakes or powder year-round.
Pesto is the most common basil product, typically made with basil, olive oil, garlic, and cheese. Packaged herb pastes and mixed seasonings often combine basil with alliums or salt.
