Buy a bag of organic onions.

1. Cut up an onion and put it on her feet. Leave in contact for at least an hour, but overnight is great too. (Put in a pair of socks or in a plastic bag.
2. Simple, magic onion soup. Like a homemade, organic Gatorade, this soup is loaded with electrolytes.) Eastern European wive's cure all. Cut up 1-3 onions. Boil them in a pot of water. (Use more or less water or onions. Do it a few times and personalize it.) If you can puree the onions after being boiled, then put them back in the onion broth, it'll be easier to consume. At the end add a tablespoon organic brown sugar or molasses. When nothing tastes good, this is an awesome way to rehydrate. After a couple days of onion soup, a person in acute illness usually responds by regaining a REAL appetite.

I have a lot more suggestions but these onion related ones are easy, low hanging fruit. You want more of my gypsy first aid care ideas, I'm here all day. ♥️ Praying for you and her.
