About Botanical / Plant Extract Ingredients
Botanical extracts are derived from plants and used in cosmetics for their purported soothing, antioxidant, or active properties. However, the "natural" origin of botanicals does not make them inherently safe — plant extracts contain complex mixtures of compounds, some of which are potent allergens.
Relevance for Witch Hazel: Essential oil-containing botanicals (lavender, tea tree, citrus), Asteraceae family plants (chamomile, calendula, arnica), and propolis-containing extracts are among the most common botanical allergens. The processing method affects allergenicity: cold-pressed extracts retain more proteins than highly refined versions.
