Rhassoul, or ghassoul (Moroccan Arabic: الغاسول, romanized: l-ġasul), is a cosmetic made of natural mineral clay mined from the Atlas Mountains of Morocco.
It is mixed with water, sometimes with herbs or other substances, to clean the body.
Rhassoul contains silica, iron, magnesium, potassium, sodium, lithium and other trace elements.
[citation needed] These deposits border the middle Atlas chain, in the Moulouya’s valley, 200 km from the Moroccan city of Fes.
It is applied as a facial mask, or as a poultice to the body with a glove, or kessa.
