beyondhom Strawberry Birthmark Query

Strawberry birthmark - on a premature baby now 8 months old - this phenomenon is apparently more likely on premmies, although it resembles a bowel protrusion, it is a birthmark, there is another one adjacent which is also growing, but which is internal.

Does anyone know of natural treatment for this? The Medical Profession offers Propanolol - for an 8 month old child!

Thanks

Jane
