How are heavy metals and pesticide residues controlled in this wintersweet oil?
Heavy metals are tested per the relevant limit standards (e.g. Pb ≤1 ppm, Cd ≤0.1 ppm, As ≤0.5 ppm per GB 2762-2022) and reported per batch; incoming flowers receive routine pesticide screening, with multi-residue scans on request against GB 2763 series / EU EC 396/2005.
