BirdLady I second Hills' suggestions.
I like a little Himalayan salt in the bath for itchy skin too.
Do get some plain porridge oats. Muslin is great, but old tights can work just as well.
After a bath, Pop a handful of oats into the fabric of choice, run under hot water until it's very squidgy and oozes thick white-ish liquid out of the cloth. Dab the liquid onto the dried itchy skin. Sometimes it takes two applications, but it'll the the fire out of eczema for several hours.
Do not rinse it off, let it dry on your skin.
You can rinse any off when you need to apply more, maybe after a lot of hours or even the next day.
dementedma Rosemary is good, as is English Lavender, especially the edible ones, sage, calendula marigold, chamomile, valerian, too many to list really. Maybe buy her a little herbal to give her a bit more interest.
Here's hoping Storm Barra is a bit kinder than Arwen to us all!
