Freshwater Green Mud, also called Sapropel is an organic sedimentary slip formed at the bottom of still freshwater lakes. It consists mainly of the remains of aquatic organisms such as algae and plants.
It is considered to be one of the most unique therapeutic muds in the world. Supposedly it doesn’t have an equivalent substance; compared with sea mud and clay, Sapropel is ten times richer in organic matter – up to 93%, which makes it perfectly usable for medical, pharmaceutical, cosmetic, and veterinary purposes.
