When handling and processing seeds the user should be aware that many seeds contain very toxic properties and must be dealt with according to 'Good Laboratory Practice'. The grinding of seeds should be carried out in an extraction cabinet and a face mask and gloves should be worn during this process. Fluid extracts may be poisonous and every care must be exercised when processing these fluids.
