Itchy skin- suggestions to ease

Hi,

 

My best friend has just been told they have lymphoma and are waiting on further tests and results. But they have awful, awful itchy dry skin. Has done for months and is all cracked on joints, and fingers etc. Theyve tried over counter moisturisers etc but nothing seems to really help. 

 

I know it isnt much given the news theyve had, but I want to do something nice and maybe make or find something that will help a little. I know home remedies can work wonders something! So just wonder if anyone has any suggestions, home remedies, tips n tricks or just a product theyve found works well!

 

Sorry I know its vague but figured asking on her might see some luck!

Wishing everyone well
