Tyrolean shale oil is a black, strong-smelling oil found in the stones of Karwendel Mountains, a mountain range of the Northern Limestone Alps in Austria and Germany.

It is also known as Ichthyol. According to legend, it is the blood of the giant Thyrsus; hence, it is also called Thyrsenblut or Dirschenblut. From the "Thyrsenblut" the healing Tyrolean shale oil is extracted. Shale oil reserves are located in the oil shale at Seefeld in Bächen Valley plate and close to Achen Lake. The oil-bearing zones lie at an angle of 51 degrees.
