Antimony can damage plants including growth retardation inhibition of photosynthesis decreases in the uptake of certain essential elements and decreases in the synthesis of certain metabolites Plants often have defence mechanisms to alleviate Sb toxicity eg a highly efficient antioxidative system and the ability to immobilise Sb in the cell wall or compartmentalise Sb in the cytosol

Agrimony is POSSIBLY SAFE for most adults when used shortterm But large amounts of agrimony are POSSIBLY UNSAFE because agrimony contains chemicals called tannins Agrimony can make
