Wrightia antidysenterica, the coral swirl or tellicherry bark, is a flowering plant in the genus Wrightia. Wrightia antidysenterica is sometimes confused with the species Holarrhena pubescens due to a second, taxonomically invalid publication of the name Holarrhena pubescens. It has long been known in Indian Ayurvedic tradition. It is known in Sanskrit as kuṭaja or ambikā and in Sinhala it is called වල් ඉද්ද (wal idda). It is also known as "white angel" in the Philippines.
