Arning tincture
Arning's tincture , also called Arning's solution (Latin solutio Arning ), is an ethanolic-ethereal solution of anthrarobine (1,2,10-trihydroxy- anthracene ) and ichthyol for the treatment of difficult-to-heal or chronic skin inflammations ( eczema ) , fungal diseases of the skin, psoriasis, etc. Ä., named after the German-English dermatologist Eduard Arning (1855–1936), who invented it in 1901.
Due to its high diethyl ether content, Arning's solution is very flammable and also difficult to store: Together with atmospheric oxygen, easily explosive ether peroxides form when exposed to light, which is why Arning's solution (like diethyl ether itself) is always stored in dark bottles should, on the other hand, is usually only prepared by the pharmacist when a prescription for this is presented.
In 2001 Arning's solution was deleted from the New Formulation Form (NRF) for various reasons .
