I really haven't had a lot of experience with this.
In TX, there were a lot of home remedies that were allowed as long as they didn't interfere with hospital/LTC rules . It all got to be so common, it was just part of the deal
Moving back to IL, and working peds, I was asked to go into practicing Muslim rooms, if infants were being breastfed, and let the mom know the doc was coming (male doc) so she could cover up before he entered the room. Poor kid got a break from eating whether he/she was done or not
I found it all interesting- and some things were just plain curteous.
