Magnesium sulfate heptahydrate (MgSO4 · 7H2O), izwi kandi nka sulfure isharira, umunyu usharira, umunyu wa cathartique, umunyu wa Epsom, ni urushinge rwera cyangwa rutagira ibara cyangwa urukuta rw'inkingi ya kirisiti, impumuro nziza, ubukonje kandi busharira gato, uburemere bwa molekile: 246.47, uburemere bwihariye 1.68 , gushonga byoroshye mumazi, gushonga gato muri Ethanol na glycerol, muri 67. Igitabo cya Himiki5 ℃ cyashonga mumazi yacyo ya kirisiti.Ubushyuhe bwangirika, 70, 80 ℃ ni ugutakaza molekile enye zamazi ya kristu.Kuri 200 ℃, amazi ya kristaline yose yatakaye kugirango akore ibintu bidafite imbaraga.Mu kirere (cyumye) cyoroshye guhinduka ifu, gushyushya byavanyeho buhoro buhoro amazi ya kirisiti muri sulfate ya anhidrous magnesium sulfate, iki gicuruzwa ntabwo kirimo umwanda wuburozi.
