Please remember that 'natural' does not always mean safe. Any natural product if abused can be unsafe.
Epsom Salt should be stored in an air tight container in a dry environment. If exposed to damp it may clump. This does not affect its use. It may be crumbled back to powder or dissolved as usual.
Please keep away from children and pets, while it is a very mild product it does have a cleansing action and in excess will cause diarrhoea.
It has an indefinite shelf life.
Please note that poor storage affects our Terms and Conditions.
