Support the nervous system's response to minor pain with Arnica liquid herb extract from Herb Pharm. We prepare our Arnica Extract from the whole flowers of Arnica montana plants which are Certified Organically Grown. To assure optimal extraction of Arnica's bioactive compounds, the plants are hand-harvested when in full flower, are carefully shade-dried to retain the full color and aroma, and are then thoroughly extracted. Do not use on broken or abraded skin. Discontinue use if irritation appears on skin or in mouth, throat or stomach. Prolonged topical use or use on broken skin may cause skin irritation.
