Phytosphingosine is a sphingoid base, a fundamental building block of more complex sphingolipids. It is abundant in plants and fungi and present in animals.^[1] Phytosphingosine has also been found to have interesting T-cell related anti-inflammatory properties in models of inflammatory bowel disease.^[2]
