Why do some European medicines mention itchy skin?
EMA recognizes traditional use for itching associated with dry skin. That category rests on longstanding use and plausibility despite insufficient clinical-trial evidence; it should not be read as proof that the oil treats eczema. 1 2
The EMA assessment covers specified extracted oils, not combinations with other herbs. A multi-ingredient product therefore cannot borrow the whole assessment unchanged. 1
