We use a few.
Insomnia or Sleep Disturbances
Bach's Rescue Remedy. This is made from the essence of flowers. It comes in a dropper bottle as well as a spray bottle. I find the spray much easier to administer. It works fast. I use it for myself too so that I remain calm. Remaining calm as a Care Giver is very important.
Hallucinations that are Frightening
Helleborus Niger 30 C. You can buy little pellets that my mom likes to refer to as "the candy." She takes them sublingual, under the tongue until they dissolve. This works to clear up confusion and helped her scary hallucinations to stop.
"I WANT TO GO HOME"
When my mom Says, "I want to go home," it usually means that she's agitated or upset about something. She isn't feeling safe and secure, something is upsetting her.
Hyoscyamus Niger 12 C. This homeopathic remedy I give to my mom when she's agitated. When she says, "I want to go home" and she's already home, it can be disturbing.
I give her an eye dropper full of a tincture in a little water; I make it by putting 5 pellets into a dropper bottle (1 oz bottle with an eye dropper cap) fill it with water and let it dissolve. Refrigerate the bottle, it makes it taste less bad.
Once my mom takes an eye dropper full of the tincture in a little bit of water, we take her out for a ride and when we get back to the house, she realizes that she's home. She is in a more pleasant state of mind where confusion is erased and peace is restored.
