What are avocado soybean unsaponifiables?

Grant Cooper, MD
Physical Medicine & Rehabilitation
Avocado soybean unsaponifiables (ASU) has been prescribed in France as A1S2 or piascledine since the early 1990s for managing the symptoms of arthritis. Saponification is the chemical process of making soap from oil and lye, and these unsaponifiables are the approximately 1% portion of the oil from avocados and soybeans that cannot be made into soap. It is called A1S2 because it comes from a mixture of 1 part avocado oil and 2 parts soybean oil.
